only if you can teach me how to use SU as well as you do

Hi Susan, Have a look at this link, http://www.thecadacademy.com/arch_solutions.asp I think it covers the information you are after. Mike PS: Thanks for the Card

Yours welcome darling

I am almost sure that this is not what the person asked you, but a standard 2D drawing exported from SU would look funny in AutoCad if one used the "hide" command. The export has no faces, so nothing happens there, but the section cut and profile edge lines are exported as wide polylines, and these lose their fill with Hide, and look meshy instead. Of course, a Regen brings all back to normal again. Anssi

Thanks Didier!

Thanks so much Todd. I will look into that. ahem, just want you more than normal, is all

Doh, I understand now. thanks so very much. Of course, it is totally obvious when someone else has thought of it. Thanks again.

This is an example of how to do it using my Grow.rb script... GrowHelix.skp

Thanks so much Bob. But it would appear that the drive is black and uncompressed so thtat doesn't seem to be the reason. Anssi, I think you are on to something. I created another user and signed on with that and when I selected a bunch of files and right clicked there was a marked difference in the hesitation time for the context menu to show up. Now I don't really want to use the new user ID because I would have to set up all the program icons all over the palce all over again. But now the question is, what is it in my user profile that is causing the slow down?

This method usually produces consistant triangulation when the countor tool is used.

Bruce, Blue is a girl. I know this because my daughter grew up watching Blue's Clues.
