AttributeError when importing mesh into preprocessor

[elmeririzarry]

With regard to importing CAD or meshes into preprocessor:

I have attempted to generate LDPM model data files using an imported mesh and get the following error (user name redacted):

10:34:59 Switching to Chrono Workbench

For context, this geometry was obtained from a lidar scan, the mesh was simplified using MeshLab, and a volume entity was added using GMSH prior to importing into FreeCAD (in *.vtk format). The following images are (1) the 3D mesh in GMSH, and (2) the result that appears in FreeCAD when attempting to run the LDPM mesh generation. I am aware this same error happens when importing other geometries, not only meshes reconstructed from lidar scans.

Thank you for bringing this to our attention. The bug should now be corrected - please pull the repo and try meshing again.
