Fusion 360 as a Viewer - Another Step in the Learning Experience

If you've spent any time at all looking into Fusion 360 you'll likely hear "the data is stored in the cloud" touted as one of it's big advantages.  

And it really is an advantage!  Here's one case that I've found where Fusion has helped augment Autodesk Inventor, but that's just the beginning!

Here's the end in mind!

What's the Scenario?

I was attending a design review for a small assembly, I may not be able to bring in my laptop, IT may not be able to install Inventor or Vault in time.

In other words, I may be on my own.  Time to think of a backup plan.  

Since I started out this post discussion Fusion 360, you may safely assume that Fusion 360 is part of the solution, and indeed it was.  

I also used A360 as a key part of my solution too. And that's where this story starts.

In short, I used Fusion 360 as my viewer. It was similar  to Inventor and I was comfortable using it. On top of that, the Fusion client is much simpler to install than Inventor, and can be done much more quickly.

Here are the steps I used to "get there from here".  In the interests of full disclosure, I'm using a sample file because the original file is proprietary.  Sorry, no peeks to that!

Here we go!

The first thing was to upload my assembly into A360 Drive.  Make sure to use the Assembly option under the Upload button.

Uploading into A360

Once that was done, browse to the folder containing the top level assembly, in this case, Engine MKII.

After hitting OK, there will be a few more questions to answer, the biggest one is which file is your actual parent file.  In this case, it's going to be Engine MKII.iam.

Choosing the parent file.  It's listed among it's candidates.

With the parent assembly selected, hit the Upload button, and the upload process will begin.

Ready to go! 

Now, the process of uploading to A360 will begin.  After a few moment, you'll get the indication that the assembly has been uploaded.

Time to Call Fusion 360

Now it's time to browse to the location you saved the file.  When you find the assembly, right click on it, and choose Create Fusion Design.

Creating a Fusion Design

Now, the converting process begins.

The upload is running

Give it a little time, and the conversion is completed.

And we're done! 

Make sure to refresh your project, and the newly created Fusion Design will appear.

The design is converted!

All that's left to do now, is double click on the file and you're ready to go with your new Fusion Design!

It's now ready to go in Fusion 360!

So what I ended up with was a quick way to use my design, without a heavy client install.  If necessary, I could even use the machine that was kept in the conference room!

I could navigate and control the visibility of parts.  Everything I needed at the time.

It was a great option that relieved a lot of stress.

Did you have any challenges uploading the file into Fusion?

I sure did!  I had some challenges loading the hardware, which was a combination of Inventor Content Center and iParts.  It wouldn't upload until I put it in the same folder as the components.

I don't know exactly why this is, but I'm going to poke around a bit more and see what I can find out.

Some of you may have a few questions on why I choose this direction.  Here are some answers to some questions you might be thinking of asking. 

Why didn't you use A360 as your viewer? 

I absolutely could have.   But I wasn't familiar with A360, so I made a decision to go with what I know.  Fusion worked great, but I know I can use A360 in the future.

Why didn't you use Project Leopard? 

Just like above, I knew it was an option, but I had less that 24 hours to make my decision, and very little experience with Project Leopard.  So I chose the path I knew.  Will I consider it the future?  Absolutely!

Did you use any of the review tools in Fusion 360?  

No.  I didn't.  And it's not because the tools don't work.  In truth, I haven't had a chance to try them yet.  The scenario simply didn't suit those tools.  But these tools do have my interest, and I'm looking for the opportunity to explore them!

And that's a wrap for this post... A little bit of what I've learned, and a few things to try in the future.

Importing McMaster-Carr Models into Fusion 360

Most of us American based engineers have used, or are at least aware of, McMaster-Carr. 

If you haven't heard of them, they are a one stop shop for everything from nuts and bolts to urinals, and just about everything in between.

And not only can you get just about anything, you can get it as quickly as the same day!  

McMaster-Carr has saved the day, on the same day, more than once for me!

Now if you're a "well seasoned" engineer, such as myself, you might remember when the only way to look at McMaster-Carr's selection was a big yellow book that guaranteed about 50% odds of muscle sprain when lifting from the shelf to the desk.

Then you had to pick up a phone, which was most likely wired to the wall, and talk to a human being.
That was the state of the art of 1998.

The McMaster-Carr catalog.   Engineering resource,
workout implement, and potential zombie apocalypse weapon. 

Then, in the 1990s, we began becoming aware of this thing called the internet, and McMaster-Carr got a website.

Engineers everywhere rejoiced.  Now there was no risk of physical injury, and we could order the parts we needed while still tanning by the light of our old cathode ray tube monitors.

A screen capture from the McMaster-Carr page

Now engineers could spend money on expensive mechanical gadgets faster and more efficiently!  And many parts had models that could be downloaded and imported into your CAD models!

A page showing the download page

They've even recently come up with an app for Android and iPhone, that lets you purchase your items using your mobile device.

The McMaster-Carr Online App

It's perfect for us introvert engineers that don't feel like talking to people!

So where is this all going?

Earlier this week, I attended an Autodesk Fusion 360 event at Hollywood 3D Printing, where I got to meet, other Fusion 360 users, and see how those users are using the new technology.

And while there were many interesting things, one feature caught my eye.

A direct link to McMaster-Carr right inside of Fusion 360.

Here's how it works.  I'm using a simple example of an oil pressure relief valve that I was modeling for a little Fusion 360 practice.  I've modeled a body that would represent the engine case, as well as the poppet in red.

The oil relief valve model in Fusion 360

But I need two things, a spring, and a set screw to hold the spring in.  Instead of creating models, I'm going to insert them from McMaster-Carr.

Here we go!

First locate Insert McMaster-Carr Component Component from Fusion 360's Insert Menu.

Locating the shortcut to McMaster-Carr.

When you choose that option, Fusion 360 will open the McMaster-Carr website.  But the key is it will open inside of Fusion 360!

The McMaster-Carr catalog in Fusion 360

Now it's just a matter of finding what you want, choosing the CAD icon, and downloading the model.

Choosing a CAD model from the catalog. 

But the key is that it downloads right into Fusion 360!

Saving the model to insert into Fusion 360

Choosing the Save will insert the model directly into the Fusion 360 model without having to downloading to a location and import, like we've had to do in the past.

Inserting the set screw

Now the model can be inserted and constrained like any component.

Just add the spring, and the model is done!   By using the catalog from McMaster-Carr, the parts I can quickly import parts that I know I can order!

What's another bonus?  When you create a bill of materials, you get the part numbers, as well as the descriptions for those parts.  That means no retyping of component descriptions and reduced risk of making a mistake.

So if you're using Fusion 360, or thinking about it, take a look at this functionality.  I think it's one you'll find is well worth it.

And I'd also encourage you to take a moment to think how far technology has come.  It was less than 20 years ago that I was writing down numbers out of a catalog, calling an operator at McMaster-Carr, and reciting numbers over the phone.

This was done after I built my own 3D models in Mechanical Desktop, because McMaster-Carr didn't have any for me to download

Now, it can be inserted directly into your 3D with models from the McMaster-Carr website, where part numbers and descriptions automatically populate your bill of materials, and ordered via the website.

How far we've come in a very short time.

Learning Fusion 360 - Building a 20 Sided Die

Many, many moons ago, a friend of mine asked me to model dice for a local gaming store, Dicehouse Games.  The trickiest of these was the 20 sided die, like I have pictured here.



Feel free to check out that post here,  I'm going to focus on my Fusion 360 experience here.  I found the steps were actually very similar.

Consider it a little bit of a musing about how my previous experience in Inventor compared to creating the die in Fusion 360.

The initial steps were the same, I created three rectangle on the XY, XZ, and YZ planes with a ratio of 1:1.618.  Just like before, I referenced this Wikipedia article here.

You may hear these referred to as the "Golden Rectangle".

The very skeleton of the 20 sided die.  The golden rectangles with a ratio of 1:1.618

Next, came the "how does Fusion 360 do it?" moment.  That meant building some workplanes using the "Plane Through Three Points" tool, and creating a sketch on that workplane.

I sketched three lines, using the three points of the rectangles as shown below.

The three point workplane with a sketch created on it.  One of the "Golden Rectangles has its visibility turned off to reduce "cluttter". 

To keep my process as simple as possible, I also created a boundary patch from the triangle.  It makes it easier to use turn off the visibility of these objects when things get a little cluttered.

The same model, with the boundary  patch added. 

Now there's a lot of "rinse and repeat" type of steps.  More 3 point workplanes, more sketches, and more lines defining triangles.

More boundary patches begin to define the "skin' of the die. 

But as I added more patches, I realized I could tweak my process a little bit, and make the operation go a little more easily.

I realized, I had enough patches where instead of using the Plane Through Three Points Workplane tool, I could use the "Plane Through 2 Edges Tool".  This was because I now had adjacent patch edges I could use to help me .

Fewer picks, faster process.

Once you have a few patches created, you can make better progress! 

There was more repeating of the now modified steps.  More sketches, more patches, until at long last, I had a complete skeleton of the die made with workplanes, surfaces, and boundary patches.

The die skinned with twenty different patches. 

Now what's left to do is to to make a solid out of it, using the "Stitch" tool.   This seals the 20 surfaces into a solid.  I now have a twenty sided solid!

The now stitched die!  Note I changed my background color to make the now solid die a little more clear. 

After this, comes the long process of adding numbers.  This will take a while.  There's no real getting around that.

Sketching in text.  Fusion 360's drag and rotation tools really helped this process. 

There was a lot of sketch, extrusion, sketch extrusion, going on here.  But finally the whole die was modeled!

Now, I added a little color.  I had experimented with orange, but went for red this time.

Dragging color onto the die using the render environment. 

After quite a bit of dragging, the colors are all done!

After adding fillets to smooth the rough edges, and the die is done!

The die completed! 

So after that exercise, what did I learn, and like about this exercise?

1) Neat little workflow in sketching! 
When you start a sketching tool, and there isn't an active sketch, Fusion will start a sketch for you.  Thanks for the help with that!!

2) Drag and drop. I like it.  That is all. 
Fusion's push pull and rotation tools on the "drag and drop functionality really came in handy.  It was nice to rotate and move text by dragging with the grips.  It made that tedious task go a little faster.

3) Keep an open mind, you might need to try a model a couple of times to get it right.
I started one model, then threw it away when I realized I wasn't making it as efficiently as I could.  I get we can't all do that, but make sure to look for the lessons to improve your flow for the next time.

4) Take the lessons you learned from one program, but don't take them too seriously.
We've all heard the frustrated user say "This program doesn't do it like MYFAVORITECAD!"  Well, no. It's not MYFAVORITE CAD.  Maybe it doesn't better, maybe not.  But at least be open to the changes before you dismiss them!



So my adventures in Fusion 360 continue.  I'm enjoying them, and I'll continue looking for ways to improve my skills set.

And if you'd like to take a look at this model yourself.  Here's a link to download it.  That's right.  Yours for the taking, enjoy!

I'm considering writing some posts describing how I built the die in a little more detail.  If you're interested, feel free to throw in a comment!

A Little More with Fusion 360 and A360 - Sharing and Embedding

Just past Thursday I attended an Autodesk Fusion 360 Meetup in Novi, Michigan.

I figured it was a little bit of serendipity, that I just happened to be in in Novi for some PLM360 training.

Attending the event was a must.  A moral imperative, if you will! 

So I sat down at the event with my laptop and began watching the presentation.

A photo posted by Jonathan Landeros (@jlanderos1973) on Apr 21, 2016 at 3:48pm PDT

Watching the presentation and building models! 

I'll say straight up, I knew many of the steps, but I learned long ago to try not to "check out" of a presentation.  There's always a gem if you know where to look. 

Here's one I'm going to share with you!  Embedding a model view on a website!

The first step is to locate the file you want to embed in Fusion 360.  In my case, I'm going to share the connecting rod from my post yesterday. 

But now, instead of just pasting in a picture,like I did above,  I'm going to embed a 3D model view into the model! 

The first thing to do is to locate the file in Fusion's data panel and click on the 'i' symbol to expand the flyout under the component. 

Once you'll see the option to "Open Details in A360". 

Clicking on the information icon

Click on that link and the file will open in A360. 

Once the file opens, click on the text next to "Shared Link" I've indicated in the image below.  It will say "On" or "Off" depending on your settings

Click on the link in A360 for a pleasant surprise. 

Selecting this link will open a window that will show you the options to Copy Link, Email, and Embed.  

Since we're embedding, embed is the option we're going to choose! 

Choosing the embed option

Once you have that, choose your size, and click the "Copy" button to paste the embed code into the destination.

Pasting the embed code

Once you have that, you're ready to go!  You'll have a viewable file that you can embed in a webpage just like I have below!

Oh! One other trick! If none of the sizes presented by A360 work for you, locate the "Height" and "Width" settings in the embed code.  You can tweak them to the size you want!

For my blog, I use 545 x 307, but you can always experiment with what works best! 

Feel free to edit the embed code. 

Fusion 360 - An Update on My New Experience

In my previous post I mentioned that I was going to start diving headfirst into Autodesk Fusion 360.  So taking advantage of a business trip to Detroit, that's what I've been using my evenings to do!

A nut plate I built in Fusion 360
You can find the part at this link

It's not that I've never used Fusion, but most of my work has been confined to a few hours here, followed by a months long hiatus.  Rinse... Repeat.

In other words, I only dabbled in it.

It's a transition for sure!  I've used Inventor since the year 2000.  I know that program, and I'm comfortable in that program.

Having worked with a CAD program for that long, and putting some long hours into using it, it becomes tempting to keep it obsessively close.

It's my CAD!  It's my precioussssss.....  

But I told myself that I had to have an open mind, and judge Fusion 360 on its own merits.  "Because its not Inventor!" is not reason enough to dislike Fusion.

So far, I've just been trying a little part modeling.  I just found a few samples and began building models.

I didn't start out with something complicated, like the Eiffel Tower or a Boeing 737, I just picked a few simple parts, and started getting acquainted with Fusion!

A connecting rod I "Made up".
You can find this part at this link.

So what did I do?  I just built!  I built parts, used the tools, and just got used to how Fusion 360 works!

And so far, having tried simple part modeling, I like what I've seen.  Many of the tools are similar to what I've used in Inventor, and I'm getting used to a few of the differences I've found so far.

I'll be diving deeper!

But I'm going to be looking at more than part models.  I already have a few colleagues I may be collaborating on projects with, and I see potential for doing a little 3D printing.

And I've already tried my hand at sharing files on this blog!

So stay tuned!  I'm enjoying the experience, and there will definitely be more to come!

Fusion 360, Growing Means Leaving My Comfort Zone

I know I've been bad about posting, but I really do have a good reason!

For the last four weeks, I've been taking another Aviation Maintenance class at Mount San Antonio College.  This class was "Induction and Fuel Metering Systems".

That meant studying carburetors, fuel injection, superchargers, and turbochargers, among other details. 

A photo posted by Jonathan Landeros (@jlanderos1973) on Mar 21, 2016 at 5:06pm PDT

For four weeks, this was home. 

It also meant working 6am to 4:30 PM Monday through Thursday, followed by class 5:30PM to 10:30PM, Monday through Friday. 

In other words, a schedule fueled by momentum and caffeine, lots of days being the first out of bed, and the last to sleep at night, and being grateful for a supportive family who understands that I'm nearly invisible these four weeks.  

But it's also incredibly rewarding, and dare I say fun, and as always, educational.  

Why?  Because I love the subject, and I love learning something new.  

A photo posted by Jonathan Landeros (@jlanderos1973) on Apr 1, 2016 at 6:49pm PDT

One of my projects was a 100 hour inspection of this RV-6's engine.

But classrooms are only the start.  Life is the biggest classroom of all, and it loves to change the lesson midstream.  

It's up to us to adapt to it!

So what does that have to do with InventorTales?  Winds of change, that's what!

I no longer have access to a license of Inventor at home, which is where I write my blogs.  And as much as I wish I could, I don't have the means to get myself a license of Inventor.  

I could close up shop, and turn off the lights on InventorTales.  After all, it's been a heck of a run! 

But why do that when I can use  Fusion 360.  

Like a sailboat changing course to take advantage of the wind, I'll be working with this program for my home projects.  

Of course that means I'll be stepping out of my comfort zone, the Inventor that I've used for 15 years!

Will it be easy?  Probably not.  Will I get frustrated?  Probably.  

But we don't grow if we're not willing to be a little uncomfortable, so this is what I'm going to do. 

Stay posted, and feel free to follow along as I head off in a new direction with my CAD experience!

Conversion Coating vs Alodine & Iridite - What's the Difference?

Things are still a bit hectic for me.  I'm busy with a new job, and I'm preparing to start up a new class in Aircraft Fuel systems.

I guess I just can't sit still!

I did want to share a short post on a funny experience at work the other day.  Definitely a case of knowing more than I thought I did!

Many of the aircraft mechanics I know about refer to "Alodining" an aluminum part.  It's a common practice to prevent corrosion on components made of non-ferrous materials.

Alodined part.  From Chem Processing, Inc.

You can find some more great pictures of parts having been "Alodined" at this link from Avon Electro.

In my Aircraft Maintenance Studies at Mount San Antonio College, I haven't had much hands on experience with the Alodining process, so it's been relegated to the "I need to read about that later" file, in my mind.

In another life, my design work, I've also worked with the "Chemical Conversion coating" of Aluminum alloys.

I knew that it was a protective coating that prevented aluminum as well.  But there are many processes, and I knew what I needed to know to design parts.

Then one day, it all came together, with a bit of humor at my expense thrown in.

I had to read up on finishes for a totally separate process, and stumbled on to a document that spoke about chemical conversion coating shared by Chem Processing, Inc.

It was short, so I let my curiosity get the best of me, and read the article.

What was one of the first lines in the article?

"Chem Film, sometimes called Alodine or Iridite"

I had to laugh at myself.  All this time, I had been dealing with the same processes, but not even known it.  

Alodining, along with Iridite, are just trade names for chemical conversion!

Alodine image from Aircraft Spruce.

In one paragraph that I stumbled on to via a web search, I had connected the dots, and realized that I had known more than I had.  I was just missing one little link.

Ultimately, I found that I had known far more than I realized.

But what was the other big lesson I learned? Or perhaps, relearned?

Ask questions!  For years.  Yes, years!  I assumed that I knew enough about Alodine and chemicial conversion coating.

And in many ways, I did.  I could design fine with it, I hadn't used it "hands on" ye.

But if I had only asked one question... "What is Alodining".  I could have bridged those gaps a long time ago.

Instead of having adequate knowledge, I would have had knowledge that could have set me a part, if only in a small way.

So that's what I share with you.  Learn from my example, my mistake.

Ask questions.  It is true when it's said the only dumb question is the one you don't ask!

I'll certainly be taking this lesson to heart.

One final note.

If you want to read more about Chemical conviersion coating yourself.  Check out the article I found at Chem Processing, Inc here.

I learned a lot from it!

Showing Trimmed Edges in an Inventor Model

My father had many a humorous saying.  One I remember came from his days as an aircraft mechanic for over 40 years.

"Mark it with a micrometer, mark it with a chalk, cut it with an axe."

It was a humorous reference to the futility we all encounter in our careers, whatever it may be.

I was reminded of this saying when I was reproducing a part that had a note indicating that a piece of standard extrusion was going to be "trimmed to fit.".

Technical translation?  "Here's extra material, so you can make it fit in the field".

An example of "Trim to Fit"

But how do we represent that in the print?

In truth, there are several ways you could accomplish this.  The one I present here, is just one idea.

First, offset a work plane the desired distance from the edge to be trimmed, in this case, I chose the maximum of .093 inches.

The first step is creating the work plane.

After the work plane is created, choose the Split command, and chose the "Split Bodies" option from the dialog box.

Make sure to choose the work plane as your split tool.

Splitting the bracket

Once that is done, create your drawing as you normally would.  But you'll notice there's a bold line where the solid representing your bracket was split.

Now comes the trick!  I'm going to make the lines representing the trimmed section dashed.  This can be done by right clicking on the lines, and choosing "Properties".

Changing the lines from solid, to dashed

Once this is done, the part to be trimmed can be clearly seen!

The indicated lines are dashed! 

There's the trick, but why use it over several other methods, such as creating sketch lines in the model, or drawing or perhaps only splitting a face?

Here are my reasons, I only ask you to consider them.

1. Splitting the part doesn't create any extra files, this approach keeps everything in the part (*.ipt) file. 
2. Changing the lines is easy to do, the split creates a "natural break", which prevents having to create any sketch "trickery".
3. The split can be moved pretty easily, by changing the work plane's offset.  This let's you represent the geometry more accurately if you desire. 

So there are the reason I chose this method.  Feel free to see what you think, and use this tip should you ever need it!

Embedding a PDF into a DWF file - I Did Not Know That!

I've been quiet on this blog the last couple of months, but life has been busy, and blogging had to take a low priority.

The last few months have felt a bit like this!  Without the fun!

But here I am, back to blogging!  This week's tip is short, but I think that it's something that might prove valuable!

During my current adventure, I saw a trick.  It's that trick that strikes so many of us.  The one that makes you say "Why didn't I try that!"

Well, at least I can share it!

Did you know that you can drag PDF documents into Autodesk Design Review and have them be accessed from the DWF file?

Here's a simple description.

Here I have a NAS (National Aerospace Standard) screw with an "offset cruciform" head.  I've exported the model from Inventor to a DWF file.

A DWF of an offset cruciform screw.

That part is well and good.  But where you hear the word "standard", there's bound to be some sort of data sheet.

The NAS standard for offset cruciform screws.

And sure enough, there is a standard available on all the sizes, part numbers, etc.  So what if you want to include this with the DWF?

Sure, you can attach both documents to an email, that will work just fine, and it's probably how most of us do it.

But what happens when the file will be downloaded, uploaded, file shared, and transported via USB?

There's always the chance that the files will become separated. 

Did you also know that you can drag and drop the PDF into the desired DWF?  All you have to do is drag it and drop the file into the browser.  The steps are simple, but there are a couple of important things to remember

1) Make sure you're on the "List View" or "Thumbnails" view in the browser.  If you don't, a new DWF file will be created from the PDF, instead of embedding the file in the current DWF.

Make sure you make the correct selections on the browser!

2) Now drag the PDF from Windows Explorer into the browser! That's it! 

Drag and drop into the browser!

3) Now you're ready!  the PDF will be converted and embedded into the DWF!

The DWF and PDF in one place!

So give it a try the next time a DWF is getting shared.  You might find it helpful!

One Last Note!

If you'd like the information on the offset cruciform screw in this blog, Coast Fabrication has a link for it here.   On the main page, you can find additional NAS standards here.

I have used this data to build a series of Inventor iParts for the fastener as well, you can find those at the GrabCAD link here. 

Enjoy!

5 Lessons Aircraft Maintenance Class Taught Me About Life

Last week, I finished up yet another class in aircraft maintenance at Mount San Antonio College.  This course was "Materials and Science", and involved learning all manner of aircraft hardware, as well as material properties, and non destructive testing.

Part of Mt.SAC's AMT lab! #aircraft #maintenance #aviation

A photo posted by Jonathan Landeros (@jlanderos1973) on Jan 4, 2016 at 4:54pm PST

Between my time of learning to identify different types of corrosion, tapping threads, and test material hardness, I had a chance to observe my fellow students, as well as reflect on how I approached and learned.  I also came to realize that my learning went beyond the syllabus of the class.

So here, in 5 bullet points, are what Aircraft Maintenance Taught Me About Life

1) Don't Forget the Details!

One of my lab exercises was making a semi rigid tube.  That meant sizing, bending, flaring, and assembling the fittings together.  The instructor made a point to say that the tubes are critical for the flares to ensuring a pressure tight seal.

Success! The key is to polish the flares until your fingerprints are gone.  Then go for another five minutes! :-) #aviation #learning #fabricating

A photo posted by Jonathan Landeros (@jlanderos1973) on Jan 13, 2016 at 9:14pm PST

I followed each of the steps carefully.  My flares were the right size, the bends were spot on.  I was feeling confident!  So with my chest puffed out in pride, I plugged it into the test rig and waited for the instructor to be impressed and proclaim me a prodigy.

The instructor pressurized it to 1000 psi, our test pressure.  He sprayed a soapy water solution to look for the dreaded bubbles that indicated a leak....  And.... bubbles....

Not a lot, but a slow and steady stream was parading out of the fitting.

The instructor pulled my tubing out of the test rig and looked into the flares.  "You need to clean those up.  I can see tool marks."  He instructed.  His experienced eye saw where the flaring tool had marked the inside of the flare.  Barely noticeable, they were causing the minor, but unacceptable leaks in my line.

So I sat the tool bench with fine grit sandpaper for 20 minutes.  I sanded until my fingers were sore, and the tips of my fingers numb.  With much less bravado, I approached the instructor and tested the tube again.

This time it passed, successfully holding 1000 psi with out a single leak!

Lesson?  Pay attention to the small, sometimes unseen details.  They can save the day when the pressure is on.

2) Don't Confuse Speed with Purpose.

There were definitely two camps in class.  There were the "fast movers", and the "slow movers".  The fast movers jumped into the projects, got their hands dirty, and got to work.

The slow movers, were a bit more cautions.  They read manuals, had discussions among themselves, and then picked up their tools.

Naturally, the "fast movers" had their projects submitted first.  But then, something interesting happened.

The "fast movers" ran into issues.  Hose fittings were over-torqued, dimensions were out of tolerance. Their progress was halted by the snapping sound of a tap breaking.

The fast movers began the process of reworking.

The "slow movers" on the other hand, while not perfect, ran into fewer mistakes, and were reworking their projects less.   Eventually, just like in the fable of the tortoise and the hare, the slower group had passed the faster group.  Their diligence meant they made steady, consistent progress.

Tapping 8-32 threads! #building.

Lesson?  Don't confuse activity with progress.

3) Good Students Memorize. Great Students Comprehend.

Our written tests were multiple choice, and the questions, which are defined by the FAA, are pretty standardized.  That translated into a lot of going over questions, making sure you knew all the answers.

This was another place that the class divided into two camps.

One camp would drill on the questions, they could ask a question, and another student could answer with "B", and repeat the answer word for word from the test guide.

The other camp, would study at home individually, then just before the test, review the questions, talk about the answer, and then talk about why a given answer was the correct one.

Come test time, the second group consistently scored higher.

Why?

The instructor, knowing the answers are standardized, change the wording of the question.  In turn, that could change the answer.  That drilled in and memorized answer, "B", suddenly became "A".

One more test, one step closer on a long journey. #aviation #maintenance #learning

Many of the students that didn't understand the concepts and memorized the answer missed these questions.

The students who comprehended the concepts, could read the question, understand what was being asked, and could reason the correct answer based on the question that had been asked.

Lesson?  Make sure you understand the fundamental concepts behind what you're doing.

4) Not Only Have a Plan, Have a Flexible Plan.

Our class had access to two mills for machining parts, and three drill presses.  The mills, being more precise, were coveted machines.

Naturally, students who needed them would jump on them right away, stake their claim and work on their projects for as long as they could.

That left other students out in the cold.

Clever students quickly learned that the mills would often open up near the end of class, when "there wasn't any time to complete a project".

But the clever students would start their projects during that time, and use the mill to size their project, or center drill holes that would later be drilled and tapped.

This meant when they walked into class the next day, if the mill wasn't available, they would use the drill presses to complete their work, using the previous nights precision work as guide.

Been a long time since I touched a mill! #machining #learning

As a result, they were still able to make steady progress through their project, while other students were still waiting impatiently for the mill.

Lesson? Have a plan, but be willing to adjust the plan to keep your goals on track.

5)  Lessons Come from Many Places.

My instructor was fantastic.  He had over twenty years of experience, he could relate his real, practical experiences to our class, making the lessons more meaningful.  But he wasn't the only one who was teaching.

My fellow students came from all walks of life.  I was one of two with engineering degrees.  There were recent high school graduates, a machinist making a career change, and a retiree learning skills to maintain his own plane.

We were wonderfully eclectic!

Those with passion showed through.  We learned from each other.

Students who had previous experience with machining helped those who had never tapped a hole.  I learned how to hand form chromoly steel from a fellow student who'd done it before working on previous projects.

When the instructor wasn't available, the clever students found another way.  Usually by learning from each other.

Lesson?  Great Mentors are all Around You.  Find Them

To end this post, I had a great time in class.  I learned a lot about aircraft grade fasteners, fittings, materials, corrosion, and testing.

But it was also an amazing lesson in life.  Making friends, working with them, and learning them, and having an opportunity to share a few lessons myself.

Most of all, I saw what my fellow students did to be successful, and I was reminded that success is not one great act, but a series of small acts repeated every day.  It's trying, it's failing, and it's dusting yourself off and having the courage to try again.

Now if you excuse me, I have a few lessons to commit to heart, and maybe think of what my next class will be.

3 for 3 :) 100% on my aircraft maintenance test! #aviation #learning
