Georeferenced coordinates issue?

[vinnividivicci]

Hi,

Thanks for this great library, I see a lot of potential!

Right now, I'm trying to use the voxelization to show diffs (added/removed) of geometry between 2 IFC files.

So far, the following is working up until "removed":

file1 = parse("older_file.ifc")
file2 = parse("newer_file.ifc")
all_surfaces_file_1 = create_geometry(file1)
all_surfaces_file_2 = create_geometry(file2)
file1_voxels = voxelize(all_surfaces_file_1)
file2_voxels = voxelize(all_surfaces_file_2)
added = subtract(file2_voxels,file1_voxels)
removed = subtract(file1_voxels,file2_voxels)
export_ifc(file2, added, all_surfaces_file_2, "added.ifc")
export_ifc(file1, removed, all_surfaces_file_1, "removed.ifc")

Although the IFC does export (also tried OBJ and it exports) it ends up in the wrong spot vs the original IFC (both rotation and position are wrong).

Am I missing an option in the script, or does it simply not currently support georeferenced models?

My IFCs are exports from Revit. In my latest tests exported to "Internal Origin".

Thanks for your time,

Vincent
