This weeks tip is one of those small tips. Something that I do a little bit differently than many people.
It's neither right, nor wrong, just a preference.
It's how I create an angled workplane on a cylinder. For example. Here I have a barrel for a paintball gun. It has several vents in the barrel, and some of them are rotated in such a way that they don't align with any of the origin planes.

Most texts I've seen use the following steps:
1) Create an angled workplane on an origin axis, using an origin plane for orientation.

| Creating the angled workplane |
2) Create a second workplane, parallel to the first, and tangent to the cylinder's surface.

| Using the first plane to create the second |
But I like to create this workplane a little differently.
First, I create a sketch perpendicular to the plane I intend to place.

Next, I draw two lines. One I use for a datum, the second I use to set the angle that I want my plane to sit at. I make sure the end of the line is coincident to the cylinder I want to create the plane on.
I then finish the sketch.
Next, I start my workplane tool, and using the Normal to Axis through Point option, I pick the end point of the line, and then the length of the line.

With this done, I have a workplane that is tangent to the cylinder and at the angle I need, albeit by a different approach.
Now all I have to do is create my hole the same way as usual, and I'm off and running.

Finally, I can right click the sketch and workplanes, and uncheck Visibility to hide it!

Why do I choose this method? I just like it. I feel like it's simpler, and faster to create this type of planes this way. No other reason!
And at long last, I've had a chance to create a video to go with my blog post! Check it out below!
So take a look at this method and see if you like it! And feel free to drop a comment!
How can I do this on the surface of a SPHERE? Dimples like a Golf Ball on a 6.00" Hollow Shell"
ReplyDeleteYou can still use the sketch option, you'll have to use the origin planes as an anchor. Depending on where you want your dimples, you may have to use a combination of angle planes etc to get the dimples where you want them.
Deletewallace. I ended up with a little spare time and put together a quick example. Super accurate, it's not, but it gives you an idea of how you might approach it.

I got this far.. So Far
DeleteSorry, Cant attach a SNIP... Will use other e-Mail...
I knew I wanted a Plane on the End of a Radial Line but, I could not figure out how to set it up..
DeleteBTW What is your Background and how did you get into CAD?
I worked a few years in sheet metal tooling, as well as for a design house making enclosure hardware (handles, latches, etc). I started on AutoCAD 14 back in the day, then moved to Mechanical Desktop, designing for those companies.
DeleteEventually I got into support and training using Inventor, Vault, and Showcase, (among a few others) today.
I take an aircraft maintenance class every semester and volunteer at a local warbird museum to try to remember "how real stuff: works. :)
