When you update AutoCAD and/or Navisworks and then try to open your your drawing in Navisworks, you might run into issues. One thing to check is making sure that the version of AutoCAD that created the DWG is set correctly in Navisworks. Sometimes with alrge companies with multiple projects using multiple versions, it could be difficult but here is how you set your “DWG Loader Version”:
- Click the “Application Menu” (Big Green A) in the upper left
- Click “Options“
- Click on “DWG/DXF” in the left column
- Adjust the year (Version) next to “DWGLoader Version“
