1D/2D Tolerance Stackup Analysis Wizard
Get precise answers in minutes.


ToleranceCalc is a 1D/2D tolerance stack up analysis wizard that enables users to analyze in minutes the effects of the accumulation of part and assembly level dimensional variations in any CAD model or drawing at any stage of the product development process.

Plus, ToleranceCalc allows users to perform "reverse" tolerance analysis for quick and easy mediation between design tolerances and manufacturing process capabilities much earlier in the product development process.

Best of all, ToleranceCalc does not require any specialized knowledge of dimensional engineering. Which means all members of product development team can use ToleranceCalc to participate in achieving total product quality goals.

ToleranceCalc can be used in conjunction with any DXF compliant CAD application on any computer running Windows (any version).

"ToleranceCalc Works. It is easy to learn and easier to use".
