SolidWorks 2013 Service Pack 5
KeyShot 5.1.66
When importing SolidWorks models and selecting the update geometry option the imported parts/layers are duplicated.
Notes:
- Uninstalled and reinstalled KeyShot 5.1.66 but error still occurs.
- The update feature does work with Rhino 5.
KeyShot support solved the problem >
"When you import solidworks files into KeyShot you have two options under the Geometry section in the KeyShot Import window: New Importer (Beta) enabled and New Importer (Beta) disabled. The reason you are seeing duplicate geometry is because your first import used our old importer (New Importer (Beta) disabled). I would try to keep the New Importer enabled at all times (specially during the first import). That should take care of this issue."
