Self-intersecting profiles

Adam Fain Sep 5, 2012 10:11 PM

I'm trying to do a sweep that involves a profile of a few circles tangent to one another. I get an error saying that they are self intersecting, but when I zoom in the sketch lines are close but do not intersect, Is there a minimum distance that SW uses to detect self intersection, and if so can i change it? Thanks.

Adam,
If the sketch circles are tangent then they are touching, they may "appear" to be close but not touching because the graphics may be segmenting the arcs.

I would use some reference geometry to move the circles apart; I've had good results with .0001 spacing between the circles.

Adam,

SolidWorks can't handle the zero thickness geometry problems that tangency would cause. You can either follow Harold's advice, or keep the tangency by making a multi-body part with multiple sweeps.
