Hello all, When I render (F6) this example from the BOSL2 documentation: include <BOSL2/std.scad> bezpath = [ [15, 30], [10,15], [10, 0], [20, 10], [30,12], [30,-12], [20,-10], [10, 0], [10,-15], [15,-30] ]; path = bezpath_curve(bezpath, splinesteps=32); rotate_sweep( path, closed=false, texture="diamonds", tex_size=[10,10], tex_depth=1, style="concave"); I get WARNING: Mixing 2D and 3D objects is not supported in file bezier_test.scad, line 348 WARNING: Ignoring 3D child object for 2D operation in file bezier_test.scad, line 348 I understand what this says and why I get this message, but what is the canonical way to get this code to render? I tried the obvious by doing a linear_sweep() and then rotate_extrude() on that, but that doesn't show anything at all. Thanks. Roel

That example renders for me. Have you perhaps added a 2d object to your file which I see is 348 lines long so it perhaps contains some other stuff.

OK so this one had me stumped for a bit, but it turns out that the actual problem is that I had a debug_bezier() call in between which I indeed did not post - I'm not sure what I mixed up there. Either way, here is the full code where I actually get this warning, which I tried on an otherwise empty file with only the content below: include <BOSL2-master/std.scad> bezpath = [ [15, 30], [10,15], [10, 0], [20, 10], [30,12], [30,-12], [20,-10], [10, 0], [10,-15], [15,-30] ]; path = bezpath_curve(bezpath, splinesteps=32); debug_bezier(path); rotate_sweep( path, closed=false, texture="diamonds", tex_size=[10,10], tex_depth=1, style="concave"); Notice the call to debug_bezier() in between, which I hadn't in my initial post. With this code I get WARNING: Mixing 2D and 3D objects is not supported in file bezier_test.scad, line 11 WARNING: Ignoring 3D child object for 2D operation in file bezier_test.scad, line 11 where line 11 is the rotate_sweep() line , which is why I was thrown off before. So it 'works' now in the sense that I know that debug_bezier() has 'side effects' (if it's proper to call it that?), but I still don't understand why? Thanks.

Do you actually want to render this with debug_bezier() in there? Seems like a strange thing to do. In order to do that you have to run linear_extrude on debug_bezier so that it becomes 3d instead of 2d. Or you need to make the path 3d before passing it, so debug_bezier(path3d(path)).
