Freeform Modeling 1

[lurks]

First of all I would like to say that I am fairly new to UG and have only been using this program for approximately six months. Basically, what I am trying to do is model a pushnut or palnut depending on how you know it as. I am having problems forming the tabs. I have included a 2D drawing of what I am trying to model. The method that I was trying was using the bridge curve tool between two short revolved sheet bodies. This method has given me no success. I did not know if there was a different method of doing this. Any help would be greatly appreciated. Thanks in advance.

What version of NX are you running?

Thank you very much that is perfect. I was unaware that you could extrude a solid with zero thickness.

Yea, that's one of those little 'tricks & tips' that you pick up along the way. I generally do that instead of creating a bounded-plane as there are more powerful editing options available with the Extrude feature.

Thanks, John. That's one for my toolbox!

John,
How did you copy the the first body that you created and array it? If you could help me with this that would be great. Thanks in advance.

Actually I just used Edit -> Transform and revolved it and made 4 copies, just that this will not result in a parametric model (the 4 copies are 'dumb'). However, if I was using NX 5, I could have used the new Instance Geometry and then it would be fulling parametric. However, for you case, I suspect that you won't be editing it much so it will work fine until you can get up on NX 5.0.

I haven't looked at the part file (internet issues at work) but you might be able to use Group Feature, then array the Grouped Feature, if this design feature is used as a Boolean of most any type, prior to NX5's Instance Geometry.

Sometimes it results in weird happenings, but it should work OK for you. You might have to include some Booleans from time to time if the array of the Group fails.
