Meters
Specifies meters as the units of measurement for the part being imported.
Millimeters
Specifies millimeters as the units of measurement for the part being imported.
Inches

Make Base Feature
Specifies that you want to make the imported facet body the design body for the Solid Edge model.
If you clear this option, all facets contained in the STL (.stl) file you are importing are placed in PathFinder as a part copy rather than a body feature. Inserting bodies as a part copy requires you to select or create a base feature.
