3DCS GeoFactor

GeoFactor, built into 3DCS Variation Analyst, provides a clear understanding of how parts relate to one another and multiply tolerance changes because of assembly and part geometry.

Which Tolerances Are Most Sensitive to Variation?

3DCS software provides GeoFactor analysis as one of its analysis methods to determine the sensitivity of tolerances. This geometric relationship is displayed as a factor, called a GeoFactor, which is a multiplier to the tolerance based on its influence in the overall assembly.

Tolerance Relationships are Not Always 1 to 1

Determine Whether Your Geometry Amplifies or Mitigates Your Tolerances

GeoFactor Analyzer adds to your analysis results by determining the GeoFactor value for each tolerance.  

Key Benefits

  • How does changing a tolerance affect overall variation - If you tighten or loosen a tolerance, how much will actually affect your assembly?
  • How does the geometry of your product affect the influence of your specific tolerances - How does the assembly process and build affect the influence of your tolerances?
  • Included in all versions of 3DCS - NX, CATIA, CREO, SOLIDWORKS, INVENTOR, 3DEXPERIENCE, Multi-CAD

Geometric Relationship Between Parts

Determine how your components relate 

View the geometric effect of your tolerances. Based off of the geometry, determine how much the geometry amplifies or mitigates your tolerances. 


  • GeoFactor greater than one amplifies a tolerance
  • GeoFactor less than one mitigates a tolerance
  • One part of the HLM Sensitivity results
