Hello,
I am using jsCad V2 with Three.js. I am trying to expand (negative) geom2 and get outline path to convert Three.js LineGeometry. But result is self intersected. Previously i am using same method with old version of jsCad (OpenJsCad Csg Api). The result is not self intersected.

Is there any solving of this?

Thank You.

yeah. this is the behavior of V2. it's probably a BUG when contracting 2D geometries, as 2D geometry must have non-crossing outlines by definition.

a fix can be done in the next version. when that will happen is a big question as everything is on hold waiting for the websites to be restored.

if you have time then please create a new issue at GitHub.
