Export Rapid Prototype Control

File Format: The format of the output file, STL or ZPR (Windows only).
Format: The format of the output STL file (ASCII or Binary). The default setting is Binary.
Stitch Tolerance: Controls how accurately surfaces are tessellated.
Max Edge Length: Specifies the maximum length of any triangle edge (in current linear units).
Flip Normals: Flips the mesh normal and the mesh display orientation
Create Wall Thickness: Makes the mesh solid by thickening the walls according the the Wall Thickness setting.
Wall Thickness: Specifies the thickness of the mesh walls.
Display Color: For ZPR format, displays stitch color assignments on the mesh in flat shaded mode.
