Because of this you can get near-coincident surfaces where part of the surface is inside and part of the surface is outside, or zero-volume regions, resulting in a render error that the output is not manifold. The fundamental source of the issue is not a bug, but an intrinsic property of the inability to rigorously compare floating point values which might have undergone trigonometric operations (like rotations) resulting in irrational values that simply cannot be represented exactly in any manner. In some cases the final render works fine, but designs with coincident resulting faces should be considered a design with undefined behavior, as a proper render result is not guaranteed. This is typically caused by differencing objects that share one or more faces, e.g.:Ĭylinder(r = 10, h = cube_size, center = true) OpenSCAD display issue with coincident faces Restart OpenSCAD and preview should function normally.ĭisplay Preview doesn't appear to work at all with the openscad.exe file, likely a sub-directory of c:\program files or c:\program files(x86).
