07:00 <gbruno> [github] renestraub opened issue #5923 (OpenScad unresponsive after start on Apple Silicon M4) https://github.com/openscad/openscad/issues/5923

08:40 <pca006132> just found that some openscad tests failed with manifold 3.1.0

08:48 <pca006132> for the minkowski that requires exact convex decomposition, I am actually wondering if there is a way to do it quickly with a simple implementation which doesn't involve CGAL...

08:48 <pca006132> we probably don't need the algorithm to be optimal in terms of complexity or the output parts, even if it generates slightly more parts it should still be fine

11:51 <Guest55> Hi there. Where is the best place to get some support for openscad? I have drawn a bow line in 1.quadrant (x>0,y>0,z=0), using rotate_extrude to create sphere shaped object in that area (x>0,y>0,z>0). When i try to add another copy of this object in area of 2. quadrant (x<0,y>0,z>0) i get message " WARNING: No top level geometry to render" or

11:51 <Guest55> "ERROR: The given mesh is not closed! Unable to convert to CGAL_Nef_Polyhedron." and i can't get around this.

12:04 <teepee> if you can put the code into some pastebin someone could have a look

12:04 <teepee> paste?

12:04 <othx> paste is https://bpa.st for .scad files and other text like long error reports, https://pasteboard.co/ or https://imgur.com/ for images
