Resetting Defaults in AutoCAD 2012 - You Arrived When I Wasn't Looking!

“Combined they could be extraordinary, but that doesn't [automatically] move them to the upper echelon. It puts them in the right path but not by default.”
Allen Weiner

This week I'm off at a two day seminar learning how to cover fabric surfaces on aircraft. 

In other words, if you're me, it's a major geek fest.

That's not a table cloth.  :-)

Since I'm spending the weekend in a hotel room, I'm not able to do much by way of video recording this week!

But that doesn't mean I can't offer up something!

I don't spend as much time in AutoCAD as I used to.  Most of the time, I'm working in Inventor, Vault, or Showcase.

But there are times I have to return to good old AutoCAD.  Like a trusty old friend, it's there for many tasks I still do, like editing dxf files, to minor edits on AutoCAD data from a different source.

The other day, I managed to break my AutoCAD.  And after trying to fix it the "old" way for an hour or two, I stumbled onto the new way. 

You know, the new way that does the job in about 15 seconds?

Back a few weeks ago, I was working on my laptop, and it just shut down.  Click.  Powered off with no warning.

I check that the power supply didn't come unplugged, and it hadn't.   Everything was powered the way it should be.

I check the underside of my laptop.  It's hot enough to fry an egg on.  I must have overheated it.  I'm in an air conditioned room, and I over heated my laptop?

I think it's time to check the cooling fans.

I finish the days task, grab the "Can o' Air", and blow a tribble or two out of my laptop's cooling fans.

I think I found my problem!

I fire up my laptop, and get a warning that my laptop did overheat.  Lovely.  It does some memory checks, and once again, is humming right along.

But a few days later, I go to fire up the AutoCAD 2012 that's part of AutoCAD Mechanical, and guess what.

All my toolbars have disappeared.  Every.  Single.  One.   Even the workspaces are gone.

So now what.  I know there are some settings I can erase that will prompt AutoCAD to reset it's toolbars.  So I search, and I search, and I search some more.

I searched so long, that my searcher was sore.

Then, during one of my searches, I find a "What's new" article for AutoCAD 2012.  What do I see?

There's a "Reset Defaults" button in AutoCAD!

What's this I see?  Reset Settings to Default?

I find the button, click it, and a few progress bars later, I'm back in action.

I can't say that I have a super tip for finding this.  I stumbled onto it through pure, dumb luck.

But I can share it and spread the word!  There's an easier way!

That's Not Supposed to Happen - Autodesk Vault 2012 - 1328 Error Installing Update 1

“A sudden, bold, and unexpected question doth many times surprise a man and lay him open”
Francis Bacon, Sr.

Recently, I was adding Update 1 to Autodesk Vault 2012.  I've done it plenty of times.  Should be a walk in the park, right?

If this install were a walk in the park, I wouldn't be spending the time writing this post! 

I run in the install.  And I get this error:

Eh?  What the?

Windows installer error 1328?  Error Applying Patch?  What? 

I check, I double check.  I double check the double checks.  Vault 2012 hasn't been updated.  It's still at "Update 0".  So it can't be "updated by other means"!

Does the user have Local Admin?  Check!

Virus scanners off?  Check!

UAC off?  Check!

Eh?  

I resort to the "Big Stick" in an Application Engineer's arsenal.  That's right.  The I call in the geek's equivalent of a B-52 air strike.

I Google it.  

Now, little Windows error... You will die.

I find the following blog post in, "Cracking the Vault" that tells me this isn't the first time it's come up. It's a *.dll file that's acting up.  Apparently it only affects "Vanilla" Vault.  The licensed versions (Vault Workgroup, Collaboration, & Professional), aren't affected.

But the good news is, I know that I'm not alone in the dark.  Now, how to fix it?

I try another Google search, then another.  After a few minutes, I have my solution.

In my best "Darth Vader" voice, I say: "I have you now!"

Except this time the perky rebel gets it.

It's found on the Autodesk discussion group, here. Near the top of the page.

It's a new *.dll!  I download it, do some swapping of files, and all is suddenly good. Progress bars move and hard drives whirr musically.

So to use a buzzword out of the corporate dictionary, what's the "take away"?  The "call to action"?

1. The obvious one.  If you run into this error, here's one way to solve it!  That's why I wrote this!
2. Google is your friend.  It can help you find documented solutions, even some undocumented solutions.  Although be careful with those, sometimes they can get you in trouble!

This is also one of those things that shouldn't be needed unless you actually run into the error.  So don't start swapping *.dlls because you can.  It's a "when necessary tool".

But when you're pinned down, it can be just the ticket to get you out!

UPDATE!  New hotfix released to repair this issue!

In my travels about the web, I found this hotfix that addresses this issue.  If you get this error (or one similar).  Install the hotfix found here!

The Tips Page - A Premier

“Language is the archives of history”
Ralph Waldo Emerson

As I've walked through my travels in "the industry", I've found that many times, it's not always a fancy feature, with chrome renderings, animations, or mutli-core whizbangs that users like.

Don't get me wrong, fancy features are always cool.  I use them quite a bit myself!

But sometimes, it's the little things, like having an automatic coffee maker, that make the daily grind a little easier.

Ohh.. Coffee maker. Like a good Inventor tip.  You make the day bearable.

They're tricks that are like "secret handshakes".  You don't see them in documentation, you only hear about them from another users that learned them from:  Where else?  Another user.

So, this week, I roll out a Tips and Tricks page on my blog.  It's a collection of those little tricks that I've picked up over time.  Not because I'm somehow more savvy than anyone else, just because I've had the good fortune of learning them.

The page is in development, so it will nearly certainly evolve over time.  I'll add more "tricks of the trade".  I may even change the layout a bit as I learn.

But here it is, in it's earliest form. I'm starting with Autodesk Inventor, but will likely add more procucts as I go.  They're set up with the intention of being browsed through in a few minutes, with links to more "in depth" explanations where possible.

Take a look!  Let me know what you think!  And most of all, enjoy!

Take a look HERE! 

Lock & Load: Loading Data into Autodesk Vault with Autoloader

“It's not the load that breaks you down - its the way you carry it”
Lou Holtz

Last week, I needed to show someone how to bulk load data into Autodesk Vault.  Typically, bulk loading data is done when a Vault "goes live", and loads existing data into Vault.  The data can be anything from AutoCAD data, Inventor data, even MS Office documents.

Thus this weeks video is inspired!  This video walks through how to use Autoloader.

It would be remiss of me not to mention two approaches to loading data into Vault.

The first is what I'm describing here, bulk load with Autoloader.

The benefits?
All the data can be loaded into Vault, flip the switch, and use Vault from that point forward.  We "flip a switch."

The drawbacks?
Autoloader doesn't want you loading files with broken links into Vault, so you'll have to resolve these before putting them in.  This can be enormously time consuming if you have a lot of broken links, and may require resources that just can't be dedicated to that task.

Autoloader found some broken links!  These have to get fixed!

The second, is "as we need it".  In other words, we'll use the current system we've been using, and all new projects will be placed in Vault. 

The benefit of this method?
Data can be culled to see what's getting put into Vault, and you can resolve broken links as you encounter them.  It's a "finer toothed comb".

The drawback?
Two systems are being maintained.  Which can complicate data management.  Not to mention that if the old system is still available, that "project inertia" can set it, where users never quite make the necessary commitment to Vault.

Which is the right one?  If you're expecting me to make a bold statement of which I believe the one method, I'm afraid I must disappoint you.

I don't believe there is one.  It's a decision that has to be based on a given situation, and where resources can be best utilized.  It depends on how broken your data is, and how much time you want to devote to using it. 

I've spent a month onsite fixing data before.  That's a lot of time fixing a lot of data.  For that company, the time was worth it, but can another company justify that?  Hard to say.  So I leave that question, "open ended".

What I can do, is give you a video showing you how you can use Autoloader.  It's a tool in your arsenal, and while it may not be the "ultimate weapon", it still gives you options when faced with getting data into Vault.

Modifying the Hole Table in Autodesk Inventor

“Not that easy, but just a boring hole.”
Kevin Hayashi

In the last Autodesk Inventor course, the subject of modifying the hole tables in the hole dialog box came up.

How did we add this new standard?

It's not something many of use do.

Frankly, that's because many times, it's not really required.  Most of us can lead a long, happy life using the default values and carry on about our business.

But what if you have to work with a difficult material that needs different holes to be used?  You may find it valuable to modify the chart.  For example, a machinist colleague of mine once told me that Inconel is so difficult to tap, that the standard tap chart table is thrown out, and a custom table is used.

It all comes down to the thread.xls chart that maintains Inventor's thread information.  By adding tabs, you can customize your hole charts! 

Just add the new tabs, and change the names!

So for those rare cases, here's a video on how to customize your hole chart inside Inventor.

One more note, I'm trying a new method of creating videos, it's going to take some practice, so bear with me as I try the new process!  I'm hoping that with a little practice and the riding of a learning curve, the videos will be better than ever!

Create New Tabs in Autodesk Inventor's New File Dialog Box

“Organize your life around your dreams - and watch them come true.”
Unknown

Every time I train an Autodesk Inventor class, I mention this particular tidbit.

How to create a new tab in your New File Dialog Box in Inventor.

Where did the Woodshop & KETIV tabs come from?

It comes in handy to help organize templates.  For example, you can move commonly used templates to the front.  Meanwhile, you can move lesser used, but still needed templates to the back.

It's simple, but many times it's those simple tricks that shave a few moments from an often repeated task that show the greatest value.

It's sort of when I got my first car with electric windows.  It wasn't like it was hard to reach over to crank down the window in my old car.  But it was sooo much nicer that I could just press the button instead! 

In short, you create a subfolder in your template directory, and save a file to it.  It's pretty simple.  But here's a video to go with it!

Documenting Sheet Metal Punches on Drawings

“Chicago is a city of contradictions, of private visions haphazardly overlaid and linked together.”
Pat Colander

Now I've returned from Autodesk training in Chicago.  The training was informative, and well executed.  Now to absorb all the information! I'll be sharing some of that knowledge as I apply it to my real world.

For this blog, I wanted to continue the lesson from my last blog post, where we created a sheet metal iFeatiure

In that last blog, Creating Sheet Metal Embosses, we saw how we could create a sheet metal punch.  Now, we'll see how we can reuse that punch, and place it on a drawing.  Once you place it on the drawing, you're able to annotate it, and take advantage of the information you placed on your punch.

Take a look at the video, and see!  We've also added some fancy new "Intros & Outros".  Let us know what you think!

Off to Chi-Town for Training

I don't mind sitting in the back row of an airliner.  Aircraft usually don't back into a crash.

Jonathan Landeros

This weeks technical blog is pushed off a bit due to training in Chicago this week.

It's going to like "drinking from a fire hydrant" as they say, but hopefully I'll come back with my head full of ideas.  Some of them may even be good ones!

Seeing colors in fall is a unique experience.  We only have three fall colors in Ca.  Green, Brown, & on Fire.

Creating Sheet Metal Embosses in Autodesk Inventor

You're better off being a brick layer if you're going to play guitar than a sheet metal worker.
Roger Daltrey

In a few short days, I'll be in front of a room full of people, teaching the sheet metal course for KETIV's Autodesk Manufacturing Academy.

It's fun, but it's also stressful and nerve wracking at the same time.  There's datasets to test, information to accumulate, & presentations to tweak in an all out effort to get everything down.

One of those items I was taking a look at was creating a sheet metal emboss.

The Finished Emboss

It's been a while since I visited this particular item.  It seems to come up, then go away for a while.  But since this particular item has returned, I decided to "make hay while the sun shined", and create a video showing how you can go about creating a punch.

So far, this is the way I've found is easiest, at least for me.  Others may have ways that they've found.  I hope the  video below gives you some inspiration.

For me, wish me luck at AMA!  My next post won't be until after Wednesday, when the event is over!

Life Lesson - When a Part Becomes Art

“Wisdom is a blessing only to those prepared to absorb it.”
Anonymous 

Sometimes lessons come from the most unexpected places. One of those lessons was an invaluable schooling on how sheet metal parts are made.  Not out of a book, or in a video.  But from an experienced hand who's been doing it for decades.

A couple of weeks ago, while working my volunteer gig at Planes of Fame in Chino, Ca.  I found myself talking to the DC-3 restoration crew.

The DC-3 undergoing restoration

The DC-3 at Planes of Fame is on the road to flying again, but needs to have some work done to it.

Tony, an Airframe and Powerplant mechanic started out working on aircraft in the U.S.Navy.  He's been at it so long, some of the ships he's served on are museums now.

He's studying a door gusset that's come out of the DC-3's door.

The gusset's location

The gusset after removal

"This part is finished." He remarks confidently.   "See here?"  He indicates the ends of the part.  "It's been drilled too many times."  I can see three holes in the part where one should be.

There's a few extra holes that shouldn't be there!

There's an extra one here too!

But Tony's lesson is just getting started.  "We're going to have to fabricate one."  His eyes narrow as he studies the part.  "The part is made out of 2024-T6, but the bend radii on the flanges are too tight.  If we try to use T6 from the start, the part will crack.  That wouldn't be good."  He smirks.

"So what's the plan?"  One of the curious volunteers among us ask.

Tony closes one eye and holds the part up, studying it.  "2024-0 will bend to that radius, but we can't use in an aircraft structure.  It'll have to be heat treated to T6 after the fact.   We'll also have to be careful about how we cut our blank.  We want to make sure our flanges are oriented correctly with the metal grain."

"Sheet metal has grain?"  One of us asks.  (I smile inwardly.  This is an answer I knew!).

"Sure does."  Tony remarks.  "Almost like wood.  If you bend along the grain, the bend has a better chance of cracking."   

The collected few of us nod.  It's been quite a lesson he's taught us.  The wisdom of decades of experience, passed on with a casual confidence.

"Yup."  Tony smiles.  "In the English Wheel for the contours, bend the flanges, we'll leave a little extra on the flanges and trim them back."  He makes a casual wave of his hand.  "A thing of beauty."

Why relate this story?  Because in our age of computer aided calculated nonlinear numerically simulated design, it's amazing to see somebody who is a true artisan of his trade.

I consider myself to have learned a valuable lesson.  A lesson I'm going to take back to my computer aided numerically simulated world.


I'm bringing back a lesson on how parts are made in the "real world".  And just as importantly, I've relearned a valuable lesson that to be a good designer, you have to understand how those parts are made.

So what are my "treasured" lessons?

• Sure I knew sheet metal had grain, and I knew it could affect a part.  But when I was designing sheet metal, we never considered it.  Now, I know more than being able to repeat "sheet metal has grain", like a trained parrot.  I understand how that grain can affect a part.
• Heat treating was another process I "sort of" understood.  I knew that T6 materials won't make tight bends without cracking.  But because my sheet metal design work was done in mild steel.  I never applied that understanding.  If we had a tight bend, we just avoided the material that wouldn't make that bend.  I never even considered having to use annealed material, then treating it after the fact.  Now that an experienced hand has explained it to me, I feel silly not having considered this myself. 

I'll truly appreciate the lessons I've learned.  I hope there's a few more in my future!

Hold that Pose! - Extracting Camera Views in Autodesk Inventor Publisher

“There are no circumstances, however unfortunate, that clever people do not extract some advantage from.”
François de la Rochefoucauld

This week I've been spending a lot of time working on one of two things.  The Autodesk Manufacturing Academy, and Autodesk Inventor Publisher.  During that time, I've learned a few tricks that can made the job go  along smoothly.

One of the challenges I encountered was working with the storyboard.  As I was moving from step to step, creating assembly (or disassembly) steps, I encountered an issue where I wanted to move a component.  That part was easy.

The hard part was that in order to select the component I wanted, I needed to zoom into to the assembly.  But the snapshot remembers that I did that, and creates a rotation I don't want.

So how do I get back to my original view?  I could try to "eyeball" it, and try to match it up, but that would be tedious, and I would probably never be exactly right.

Fortunately, a tool called "Extract Camera" helps with that.  By using this tool, we can extract a camera view from one snapshot, and place it on the current camera.

Right click on a snapshot and choose "Extract Camera"

It's great when you need to rotate your view to see something, then match it up to another snapshot.

It wouldn't be a blog post without a video, so hears the video to go with the post!

Life Lesson: The Temp Directory is not Infinite!

Yeah, it felt a little like that!

Sometimes it pays to check the obvious!  Occasional "spring cleaning" of your CAD machine is always a good idea too!

Just today I was working with Autodesk Showcase, prepping some models for KETIV's Autodesk Manufacturing Academy.

I notice Showcase has started to slow down.  I'm not over-tasking it, I've run larger models at higher resolutions.  

But it's still seeming sluggish.  I perform the "three finger salute" (Ctrl + Alt + Delete) and check the task manager.

My machine is running fine.

I'm getting ready to try a new video driver, although I wasn't having problems a few weeks ago....  Why so slow now?

Then I think, "I wonder what my Temp directory looks like?"

I open up Windows Explorer and type "%temp%" to take a peek under the hood. 

My Temp directory looks like the aftermath of a frat party that was simultaneously hit by an hurricane. 

In other words, it's a mess!

I use "Ctrl +A" to select all the files.  I hit delete.  I don't even bother checking the size of the directory.  It's time to get serious.

And with this Temp directory, I wanted to be SURE!

Windows counts the files as it prepares to delete them.  The total size of the collected files climbs like an altimeter on a space bound rocket.

Finally, the numbers settle at nearly 5GB worth of  files!

Suddenly, I can hear Adam Savage of Mythbusters fame proclaming; "There's your problem!"

After a few minutes, the Temp directory is as clean as I can get it.  There are always some files in use, so you can never get every last one.

I open up Showcase, and try the same model.

It was night and day!  Showcase maneuvered around as smoothly as my memories recalled.

What's the lesson!  Check that temp space!  It clutters up over time, and keeping it clean can really help your performance!

Don't let it get to 5GB like I did! 

Pushing My Blog Post back

 Delay is preferable to error.
Thomas Jefferson

I'm afraid this is one of those weeks that I have to push my blog back a bit.  It was a pretty intense weekend building some Autodesk Inventor Publisher videos, so a quality post was a pipe dream.

The good news is I did get some ideas for my next tip!  Look for it soon.  I'm hoping to have something by mid week!

One Fell Swoop - Affecting Multiple Snapshots in Autodesk Inventor Publisher

“In one fell swoop they could make a pretty big dent.”
Harry Schuhmacher

This week I found myself working with Autodesk Inventor Publisher again.   As I worked with it, I realized that each storyboard snapshot had it's own camera view set.  So as you moved through to each snapshot, the camera was constantly zooming in and out.

In some cases, I liked it.  In others, it was unnecessary, unless part of my goal was to give my views motion sickness.

I also wanted to change the material on some of my snapshots, but the materials are also set per snapshot.  Hmm.  I didn't want to have to click through each snapshot and set the material.

How to I affect all my slides at once?

So, what to do?

With a little bit of searching, I found the solution.  If you right click on your story board, you can choose the snapshots affected by your action.

Here's the little gem!

Some of the choices I've come to like are:

• Choose Selected Snapshots - Be sure to use the Ctrl+Left Click, or Shift+Left Click to choose your slide)
• Choose All Snapshots - The "fell swoop" option
• Choose Preceding Snapshots
• Choose Following Snapshots

Give them a try!  I think you'll find they help a lot!

And of course, here's a video to go along with what I've described!

Wash, Rinse, Repeat (my work features)

“It is not worthwhile to try to keep history from repeating itself, for man's character will always make the preventing of the repetitions impossible”
 Mark Twain


While enjoying the day off for Labor Day here in the United States, I got to thinking about some of the settings I change right away on a new installation in Autodesk Inventor.

One of those settings is the "Repeat Command" option in Work Features.

The default behavior for Inventor when your placing a work plane, work axis, or work point is to place the work feature, then exit the command.

While many users like that functionality, I like to stay in the command until I exit with the escape key, or by right clicking and hitting "Done".

Fortunately, Inventor allows for this.  While in the Work Feature command, right click and check "Repeat Command".  From that point forward, the command won't exit until you tell it to.

Repeating a Work Feature Command

It's a nice little feature, and one not everyone knows about!

Tricks o' Me Trade ol' boy, Tricks o' Me Trade!

Tricks of Me Trade, Boy-O.  Tricks of Me Trade!
Jack Dalton in MacGyver (Jack of Lies)

When working in an assembly, one of the tricky things can be trying to pick a narrow edge when using the mate constraint.  Murphy's Law grabs you by the lapels, then shakes vigorously like a bartender shaking a martini. 

You can pick every edge, sketch line, and point, but never get the face you want.  If you're on your forth cup of coffee, you probably can't even hold your hand still enough to use the "Select Other" tool.

So now what?  You could zoom in to the part so closely you feel like your reenacting the "extreme closeup" scene from Wayne's World.  But that can get a little irritating.

You could hold your breath, grab your mouse hand by the wrist, and stick your tongue out the corner of your mouth until you can steady yourself enough to make the pick.  But that just looks silly.

Or you could learn this trick I picked up from somewhere in my past.  I wish I could tell you who showed it too me, but that recollection has fallen to the fog of Autodesk Universities past.

What's the trick?  Instead of using Mate, choose Flush first.  Why?  Flush sees ONLY faces.  It doesn't pick edges, points, or sketches.  Only faces.  Once you have your faces selected, switch back to Mate.



It's like it's own filter!

Using Flush to filter faces.  Try saying that 5 times fast!

Give it a try.  It's pretty quick, simple, elegant, and a lot easier than you might think.

Plus, you don't have to cut back on your coffee intake!

And here's a quick video version!

Creating Narrative Assembly Instructions - Camtasia Studio and Inventor Publisher United

Typing the quote just doesn't have the same effect.  So let's hear it from Gene Wilder himself:

For this weeks blog, I had a crazy idea, and opted to go a bit off the page. 

For years I've been using Camtasia Studio, by Techsmith, to create the videos you seen in so many of my blogs.

Then in the last few weeks, I've been working with Autodesk Inventor Publisher, and talked about exporting video files from Inventor Publisher

Then one night, it occurred to me, and I had that moment that Gene Wilder spoke of so well. 
Camtasia Studio for years.  Inventor Publisher can export a video format.  Why not combine the two?"

Using Techsmith's Camtasia Studio for editing my Autodesk Inventor Publisher video

So I did.  Here's the result.  It could definitely use some polish.  But for a first try, it's not too bad (at least I think).  I could probably add a few more bubbles, and tweak the narration a bit more.

Perhaps some of you out there in the "Cloud" can share some of your thoughts on how you might approach something similar?

In any case.  Here's my video.  Take a look, and let me know what you think!

Delaying this Weeks Post a Bit

Life is too short for traffic.
Dan Bellack

I've got to put this weeks post off a day or so.  I was fortunate enough to drive to Las Vegas for a good friends wedding, but not so lucky as to get back at a reasonable time.

Why?  A see of taillights.

Why me?

The normally 4 hour drive ended up taking more like 7 hours.

So after getting home at midnight, I thought it best to save the post, and get to bed.

Tomorrow is a work day!

I'll post as soon as I can.  I've had some interesting ideas combining Techsmith's Camtasia Studio editing capabilities, with an *.avi generated by Autodesk Inventor Publisher.

Exporting Your Inventor Publisher Data - The Final Step

“He who distributes the milk of human kindness cannot help but spill a little on himself”
James Matthew Barrie

At long last, my next  (and final, at least for now) video in my Autodesk Inventor Publisher series of videos!  We're going to publish your Inventor Publisher data into "publicly" consumable format.

Those formats can be one of several.  Microsoft Word documents, Adobe PDFs, Adobe Flash, Autodesk DWF formats, and even files for the Autodesk Inventor Publisher formats for iPhones, iPads, and Android mobile devices.

Example of an image Exported from Inventor Publisher

So the first thing we'll have to decide is what format is the best for the end user we want to supply.  That will ultimately a decision based on the best format to send to the end user.

So far, we've seen how we can create the formats, adjust the timing of our instructions, as well as add annotations to the instructions.

In this video, we'll talk about exporting the instructions and finally get them distributed to the users who will be using them!

Busy Weekends, Avengers, and Learning from the Past

“The truth should never die. It is our mission to keep the true history of 'our' side alive for our descendants.”
Grady Howell

Another busy weekend has prevented me from putting together my next planned Inventor Publisher video.  I promise to get one out as soon as I can.

I can at least see the light of day with my current projects, and I'm pretty sure it's not an oncoming train!

But on a "tangent blog", I thought I'd share an anecdote picked up from my volunteer work at Planes of Fame in Chino, Ca.

I recently began learning out to recover control surfaces in fabric.  That's right.  The old school cloth and fabric rudders, ailerons, and elevators. 

My first assignment?  Not a trip to the shop to get dirty.  Start reading the manual.  Get familiar with the process, so you know what we're doing, and why we do it.

After that, I finally after a couple of weeks, I got to start working on a real project.  The rudder of a TBM Avenger.

The rudder of the Avenger looking from the bottom up.

The first thing I'm told before we start looking at it?  "This is more art than science."

We begin working.  Actually, they're doing more working, I'm doing more watching.  But I'm learning the art of tugging, stretching, and; cutting the fabric to fit around the curved surfaces of the rudder.

As the project progresses, the team stands up and studies a compound curve.  They discuss whether or not the material will shrink around a given bend when heated.  If it should be cut instead, and if so, where it has to be cut, and how many cuts are required.

And if we cut the fabric, here, that's going to have an effect two steps down the line, so that has to be considered too.  

It's an exercise in patience and planning.

So why would I put this in a blog?  This is about CAD software, not about seventy year old warbirds.

I put it in here because the planning of the project is as important as the process, maybe even more important.  Even the veterans of doing this have to check the manuals, stop and talk over a step in the process, and even step a way for a few minutes to pace around the hangar until inspiration comes.  (These are referred to as "coffee breaks").

Starts sounding a bit like an implementation, or maybe an installation or software upgrade, doesn't it?

So that's where my observations are this week.  A reaffirmation of all those times that I've wanted to charge ahead, get 'er done.  All those times I've wanted to "make it happen" so we can get to happy hour and high five for a job well done.

The same rudder, a little bit closer now.

What did I learn from those guys stretching the fabric on a 70 year old Avenger's rudder?  The experts know what they know, and they also know what they don't know.   

Don't neglect your planning.  And when you think the planning is done, self check yourself as you go forward.  You never know when you may learn a better way to do things.
