AutoCAD (Versions: R14-2000i)
Your design must be a three-dimensional solid object to output an STL file.

1. At the command prompt type “FACETRES”
2. Set FACETRES BETWEEN 1 &10. (1 Being low resolution and 10 high resolution for STL Triangles)
3. Next, at the command prompt type “STLOUT”
4. Select Objects
5. Choose “Y” for Binary
6. Choose Filename

4. Set absolute facet deviation to 0.000395
5. Select Binary > OK

IronCAD

1. Right Click on the part
2. Part Properties > Rendering
3. Set Facet Surface Smoothing to 150
4. File > Export
5. Choose .STL

Mechanical Desktop

1. Use the AMSTLOUT command to export your STL file.
2. The following command line options affect the quality of the STL and should be adjusted to produce an acceptable file.

o      Angular Tolerance - This command limits the angle between the normals of adjacent triangles. The default setting is 15 degrees. Reducing the angle will increase the resolution of the STL file.

o      Aspect Ratio - This setting controls the Height/Width ratio of the facets. A setting of 1 would mean the height of a facet is no greater than its width. The default setting is 0, ignored.

o      Surface Tolerance - This setting controls the greatest distance between the edge of a facet and the actual geometry. A setting of 0.0000 causes this option to be ignored.

o      Vertex Spacing - This option controls the length of the edge of a facet. The default setting is 0.0000, ignored.
