Did anyone else's bulldozer import upside down when following the import instructions of the video? I made sure forward was 'Y Forward' and up was 'Z Up' as well as setting the clamp size to 5.
Additionally, I tried to import with up set to '-Z Up' to see if that would correct the problem and it did.
Same here: Z up it came in upside down using -Z for up is was correct. I think is may be something from 3D builder export
