Paper Model can't export #69

Closed Batleram closed 5 years ago

Batleram commented 5 years ago

Whenever I try to export some objects, this error message appears:

Exception ignored in: <function Unfolder.del at 0x7f580507c048> Traceback (most recent call last): File "/home/atelier/.config/blender/2.80/scripts/addons/io_export_paper_model.py", line 192, in del self.mesh.delete_uvmap() AttributeError: 'Unfolder' object has no attribute 'mesh' Traceback (most recent call last): File "/home/atelier/.config/blender/2.80/scripts/addons/io_export_paper_model.py", line 1810, in execute unfolder = Unfolder(self.object) File "/home/atelier/.config/blender/2.80/scripts/addons/io_export_paper_model.py", line 186, in init self.mesh = Mesh(bm, ob.matrix_world) File "/home/atelier/.config/blender/2.80/scripts/addons/io_export_paper_model.py", line 304, in init edge.calculate_angle() File "/home/atelier/.config/blender/2.80/scripts/addons/io_export_paper_model.py", line 706, in calculate_angle self.angle = asin(normal_a.cross(normal_b).dot(self.vector.normalized())) ValueError: math domain error

It seams pretty random which objects do this. I can provide additional information if needed.

I use Blender 2.8 on ubuntu mate 64bit

I tried the new version tlecomte provided but the problem persists. I can send you the object so you can do some further testing if that is what you wish to do.

Battleram, the fix provided by tlecomte should certainly fix the error that you posted. If problems persist, please post the whole error message again.
