Hi,
I want to make a screw so I sweep a three sided poligon and use an helix for rail. It works fine except any further commands take a long time to execute.
That does not affect other applications that are running on the computer at the same time, only Moi3D is affected.
Why is that and what can i do to prevent it?
Thanks,
Gaston

Hi Gaston, you're probably running into the problem of projected intersection snap taking a long time to handle that case, since a projected helix is a highly self-intersecting curve.

Try turning off the projected intersection snap as described here:

Thanks Michael.
Yes that does it :o)
What is the down side if I leave that option off?

Hi Gaston,

> What is the down side if I leave that option off?

It means you won't get "apparent intersection" snaps, which you probably won't really miss - see here for an explanation for what that is:

Thanks Michael, that clears things up very well :o)
