Get/Set Methods

Return Value


Output as - Binary

ISldWorks::GetUserPreferenceToggle(swUserPreferenceToggle_e, swSTLBinaryFormat)

ISldWorks::SetUserPreferenceToggle(swUserPreferenceToggle_e, swSTLBinaryFormat, <OnFlag>)



Output as - ASCII

ISldWorks::GetUserPreferenceToggle(swUserPreferenceToggle_e, swSTLBinaryFormat)

ISldWorks::SetUserPreferenceToggle(swUserPreferenceToggle_e, swSTLBinaryFormat, <OnFlag>)



Output as - Unit


ISldWorks::SetUserPreferenceIntegerValue(swUserPreferenceIntegerValue_e.swExportStlUnits, swLengthUnit_e.<Value>)

Valid options as defined in swLengthUnit_e:

  • 0 = swMM (millimeters)   

  • 1 = swCM (centimeters)  

  • 2 = swMETER

  • 3 = swINCHES

  • 4 = swFEET


Resolution -

  • Coarse
  • Fine
  • Custom



ISldWorks::SetUserPreferenceIntegerValue(swUserPreferenceIntegerValue_e.swSTLQuality, swSTLQuality_e.<Value>)

See swSTLQuality_e for valid options

Specifies the resolution of the output for STL files

Resolution - Deviation - Tolerance


ISldWorks::SetUserPreferenceDoubleValue(swUserPreferenceDoubleValue_e.swSTLDeviation, <Value>)

Double value

Specifies deviation tolerance, which controls whole-part tessellation; lower numbers generate files with greater whole-part accuracy

Resolution - Angle - Tolerance


ISldWorks::SetUserPreferenceDoubleValue(swUserPreferenceDoubleValue_e.swSTLAngleTolerance, <Value>)

Double value

Specifies angle tolerance, which controls smaller detail tessellation; lower numbers generate files with greater small-detail accuracy, but those files take longer to generate

Resolution - Show STL info before file saving

ISldWorks::GetUserPreferenceToggle(swUserPreferenceToggle_e, swSTLShowInfoOnSave)

ISldWorks::SetUserPreferenceToggle(swUserPreferenceToggle_e, swSTLShowInfoOnSave, <OnFlag>)

Boolean value

Specifies whether to show STL information before saving the file

Resolution - Preview before saving file

ISldWorks::GetUserPreferenceToggle(swUserPreferenceToggle_e, swSTLPreview)

ISldWorks::SetUserPreferenceToggle(swUserPreferenceToggle_e, swSTLPreview, <OnFlag>)

Boolean value

Specifies whether faceted model preview is displayed in the graphics area

Do not translate STL output data to positive space

ISldWorks::GetUserPreferenceToggle(swUserPreferenceToggle_e, swSTLDontTranslateToPositive)

ISldWorks::SetUserPreferenceToggle(swUserPreferenceToggle_e, swSTLDontTranslateToPositive, <OnFlag>)

Boolean value

Specifies whether exported parts maintain original position in global space, relative to origin

Save all components of an assembly in a single file

ISldWorks::GetUserPreferenceToggle(swUserPreferenceToggle_e, swSTLComponentsIntoOneFile)

ISldWorks::SetUserPreferenceToggle(swUserPreferenceToggle_e, swSTLComponentsIntoOneFile, <OnFlag>)

Boolean value

Specifies whether to save the assembly and its components to a single file

Check for interferences

ISldWorks::GetUserPreferenceToggle(swUserPreferenceToggle_e, swSTLCheckForInterference)

ISldWorks::SetUserPreferenceToggle(swUserPreferenceToggle_e, swSTLCheckForInterference, <OnFlag>)

Boolean value

Specifies whether to check for interference prior to saving assembly document; swUserPreferenceToggle_e.swSTLComponentsIntoOneFile must be set to true
