computer freeze when using sweep

[Menolik]

I have a flattened helix that I would like to sweep a circle around. Whenever I try to do this; my computer freezes. When I try it by setting the helix's height to a minimum value, it says that the shape cannot be swept. What could be causing this?

[ReMark]

I've only had one cup of coffee this morning and my brain is kind of foggy so forgive me for asking. How did you expect to sweep a circle around a flattened helix? That's why AutoCAD is prompting for a minimum height value. The sweep should have been done with the helix still in 3D.

 

Your system either froze because it couldn't complete the process or perhaps it is a memory issue. How much onboard RAM do you have?

I just need to make a spring with no rise. Like a watch spring.

Oh I have 2gb ram

So you want a coil, not a helix? Did you make the cross-section profile such that it does not self-intersect?

 

Is this going to be game of 20 questions or are you going to attach what you have so far?

 

Have you gone through the tutorials in my signature?

 

Is something like Fig 38 in Tutorial 1 what you are after?

You could EXTRUDE the circle using the Path option: http://www.we-r-here.com/cad/tutorials/level_3/3-7a.htm

Nevermind I'm an idiot. I just swept it around a helix of a certain height and then used the grip to flatten it.

Sounds like extra work. You should be able to use the Helix command to create a coil path for sweep.
