Lost sketch edges after extrude

Post by iljam »

Hi.
I am having trouble extruding a simple sketch.

When I extrude with the "solid" option off, I get a normal result: faces of the contour.

When I choose the "solid" option, one of the edges of the cut-out gets lost.

The sketch is fully constrained and drop-dead simple.

Any ideas or workarounds?
Thanks in advance!

Hi!
This is a typical symptom of a double line in a sketch (two lines exactly on top of one another). To find them, I usually delete all constraints, and drag the sketch apart.

Or since there are not so many elements in that sketch, select them one by one in the Elements list at the bottom of the Tasks panel. Identifying the duplicate should be pretty straightforward.
