Creating STL Files from CAD programs

(Please note, these are only general guidelines and may not work or produce the best possible STL file in come cases. Please consult your user's guide or the software's developers for more information or technical support.)

Alibre™

  1. File
  2. Export
  3. Save As> STL
  4. Enter File Name
  5. Save

AutoCAD™ (Versions: R14-2000i)

Your design must be a three-dimensional solid object to output an STL file.

  1. Make sure the model is in positive space
  2. At the command prompt type “FACETRES”
  3. Set FACETRES between 1 & 10 (1-low resolution and 10-high resolution for STL Triangles)
  4. Next, at the command prompt type “STLOUT”
  5. Select Objects
  6. Choose “Y” for Binary
  7. Choose Filename

CADKey™

  1. Choose Stereolithography from Export Options
  2. Enter the Filename
  3. Click OK

I-DEAS™

  1. File > Export > Rapid Prototype File > OK
  2. Select the Part to be Prototyped
  3. Select Prototype Device > SLA500.dat > OK
  4. Set absolute facet deviation to 0.000395
  5. Select Binary > OK

Inventor™

  1. Save Copy As
  2. Select STL
  3. Choose Options > Set to Medium or Low
  4. Enter Filename
  5. Save

IronCAD™

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

Mechnical Desktop™

  1. Use the AMSTLOUT command to export your STL file
  2. The following command line options affect the quality of the STL and shoud be adjusted to produce an acceptable file.
  • Angular Tolerance – This command limits the angle between the normals of adjacent triangles. The default setting is 15. Reducing the angle will increase the resolution of the STL file.
  • Aspect Ratio – This setting controls the Height/Width ration 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.
  • 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.
  • Vertex Spacing – This option controls the length of the edge of a facet. The default setting is 0.0000, ignored.

ProE™

  1. File > Export > Model (or File > Save a Copy)
  2. Set type to STL
  3. Set chord height to 0. The field will be replaced by minimum acceptable value.
  4. Set Angle Control to 1
  5. OK

ProE Wildfire™

  1. File > Save a Copy > Model
  2. Change type to STL (*.stl)
  3. Set Chord Height to 0. The field will be replaced by minimum acceptable value.
  4. Set Angle Control to 1
  5. OK
