Blender Version
Broken:
2.8 release
2.8.2 alpha (23e1fb365b65)

Short description of error
VRML2 (.wrl) import fails with ZeroDivisionError
It divides by zero inside import_x3d.py (for me in line 2047), because a bit earlier x_min and x_max are the same.

ZeroDivisionError: float division by zero

Exact steps for others to reproduce the error

Import the file into blender. (from kicad-packages3D ).

@mont29, you are one of the maintainers of this addon.
Do you mind taking a look?

Reconfirmed, still an issue, setting back to normal priority since we support X3D by default.
(still need to check internals, might be invalid geometry or Addon not supporting totally flat objects?)
