  1. Click Application menu Export Other Formats.
  2. In the Export Data dialog box, enter a file name.
  3. Under Files of type, select Lithography (*.stl). Click Save.
  4. Select one or more solid objects. All objects must be entirely within the positive XYZ octant of the world coordinate system (WCS). That is, their X, Y, and Z coordinates must be greater than zero.
