Exception while exporting #34

Closed x2b closed 7 years ago

x2b commented 9 years ago

Hey there,

not sure if this is still maintained, but anyways... I am seeing the following exception while exporting a model:

Traceback (most recent call last):
  File "/home/asdasdasd/.config/blender/2.73/scripts/addons/io_export_paper_model.py", line 1837, in invoke
    self.unfolder.prepare(cage_size, create_uvmap=self.do_create_uvmap, scale=sce.unit_settings.scale_length/self.scale)

    return (vec.y / vec.length + 1) if ((vec.x, vec.y) > (0, 0)) else (-1 - vec.y / vec.length)
ZeroDivisionError: float division by zero

If you want me to provide you with the file, please tell me.

I believe the file will not be necessary this time, the last two lines tell quite everything. Please, check if I fixed the script correctly.

Well, we are one step further apparently :)

Traceback (most recent call last):
  File "/home/asdasdasd/.config/blender/2.73/scripts/addons/io_export_paper_model.py", line 1813, in execute
    self.unfolder.save(self.properties)
  File "/home/asdasdasd/.config/blender/2.73/scripts/addons/io_export_paper_model.py", line 195, in save

    sin, cos = edge.y / edge.length, edge.x / edge.length
ZeroDivisionError: float division by zero

Edit: The mesh is not even messed up, but the mirror modifier seems to do some strange things...

Sorry for the delay. This time I'm not sure what exactly is going on, but it should not matter much. I changed something. Does the export finally work?

addam commented 7 years ago

Long time no see. I believe the bug has been fixed, and therefore I close this issue.
