Sweeping creates nonplanar faces #1

Closed oysteinkrog closed 9 years ago

oysteinkrog commented 9 years ago

I've been using 3D sweeps in my current project and so far it has been awesome. However I am getting warnings about nonplanar faces when rendering... I've been using the snapshots, currently I am using (Win x86-64 2014.12.04) but the problem was present in earlier snapshots as well.

I found that even the example in sweep-test.scad has this problem, additionally it seems to render/preview wrong.

If I modify the sweep-test.scad example to use rectangle_profile (instead of square) the problem appears to be fixed, but in my own project the problem appears anyway.
