STL Export Options DialogKeyCreator \ File \ Export \ STL-Export \ STL-Export-Options-Dialog
The following dialog appears after you have configured the settings available from the Save As dialog.
Options Specific to Solids and Sheet Bodies
Normal Angle Tolerance- Enter a value limit to control the angle normal spacing between adjacent polygons in the STL export. Default set at 15, reducing value will increase the overall resolution of the STL (which will effect the overall file size of the STL export.)
Surface Facet Tolerance- Only the corner points of polygons actually lie on the surface; the interior is allowed to separate. This tolerance options control how closely the polygons conform to the surface of the model. The default is set at 0.01, decreasing the value from 0.0 (which ignores this setting at the 0.0 value) will increase the 'smoothness' so the object will look less faceted on import. File size will increase at lower values then the 0.01 default (as more polygons are produced at lower settings.)
Verify Normals- On export will verify all normals are facing the same direction, if one or more are flipped a Reverse Body Normals dialog will appear to correct any reversed normals.
Output File Format
You can choose to output the STL in Binary or ASCII format.
The following settings also are available from the Generate STL File dialog box:
