Boundaries should be closed #13

Closed PhilReinhold closed 10 years ago

PhilReinhold commented 10 years ago

Please note http://www.rulabinsky.com/cavd/text/chapc.html section C.4

 Note that boundaries must be closed explicitly, so the first and last coordinate values must be the same

It appears to me that this was not the behavior of gdsCAD currently.

Yes, you're right, boundaries should be closed. This was the behaviour until a recently. Looks like it was lost inadvertently. The previous (now lost) scheme was to add the extra closing point only when the boundary was saved. But adding the point explicitly on creation is better. Thanks.
