CAD-Neutral Tolerance Stack-Up Analysis Wizard

ToleranceCalc is a powerful software wizard that enables any user of any popular CAD application to verify effects of 1D/2D tolerance stack-up on critical part or assembly features with unprecedented ease, speed, and accuracy.

ToleranceCalc works directly with CAD geometry without the need of "mathematically re-describing" the problem - it eliminates tedious and error-prone manual entries of nominal values. ToleranceCalc concurrently performs min/max, worst-case, and Monte Carlo statistical and sorted "percent contribution" sensitivity analysis.

With ToleranceCalc 1D/2D tolerance stack-up analysis at any stage of the design process is as easy as 1, 2, and 3:

  1. Sketch the tolerance vector chain in CAD using model or drawing geometry as overlay and save it in DXF file format.
  2. Load the DXF file in ToleranceCalc, enter tolerances, and click a button
  3. See results in seconds!

Bridge between engineering and manufacturing

Best of all, ToleranceCalc does not require any specialized knowledge of dimensional engineering or statistical tolerance analysis. Which means all members of the development team can participate in achieving overall product quality goals. ToleranceCalc acts as a bridge between design, quality, and manufacturing requirements.
