I noticed that the the matrix that I get from WT_Units:
WT_Matrix original = units.application_to_dwf_transform();
have some correct values, and some other strange values like 2,89e-14. Is this normal? I could alter the values in the transformation matrix but I don't think that is the correct approach.
And i should be using units.transform_from_DWF_to_application(), not units.application_to_dwf_transform(), because I want the original DWG coordinates, but the output coordinates makes even less sense.
