ToleranceCalc FAQ


What is ToleranceCalc?

ToleranceCalc is a software wizard that makes 1D/2D tolerance stack up analysis of CAD parts and assemblies at any stage of the product development process as easy as "spell checking".

What are the benefits of ToleranceCalc?

ToleranceCalc assures strategic success that results from including tolerance considerations as an integral and early part of the overall design process. With ToleranceCalc you will avoid costly redesigns caused by arbitrary allocation of tolerances.

Specifically, ToleranceCalc will help you from concept to production to:

  • Perform Min/Max, Worst Case, and Monte Carlo Statistical analysis of 1D and 2D tolerances.
  • Perform percentage sorted Sensitivity Analysis of 1D and 2D tolerance contributors.
  • Obtain quality and reject rate analysis for any combination of linear and angular tolerances.

Who should use ToleranceCalc?

ToleranceCalc does not require any specialized knowledge of dimensional engineering. Which means all engineers and designers using CAD can quickly benefit from ToleranceCalc to participate in quality-driven product development.

What is "reverse" tolerance analysis?

ToleranceCalc is a unique tool for upfront mediation between design tolerances and manufacturing capabilities. In ToleranceCalc you can enter your manufacturing process tolerances and then perform Monte Carlo statistical analysis using uniform distribution. In the results pane you can enter the specified design tolerance and receive reject rate and sigma value. Conversely in the results pane you can specify the desired Sigma quality value and receive the design tolerance for the chosen manufacturing process.

I use spreadsheets for tolerance analysis. How is ToleranceCalc different?

Spreadsheet based solutions first require you to convert geometry data into numerical information that you enter manually in the spreadsheets - a tedious process subject to errors. Then you must define and setup complex formulae to analyze the tolerances, a process, which requires specialized knowledge of statistical analysis.

ToleranceCalc works directly with geometry saved in CAD. Manual entry of nominal values is not required. Plus, all analysis calculations are already built in. You simply enter the tolerances for each contributor as applicable and click a button. ToleranceCalc does the tedious work for you to automatically deliver high value answers in seconds.

How long does it take to learn ToleranceCalc?

Less than 15 minutes.

What are the system requirements to run ToleranceCalc?

ToleranceCalc can be used in conjunction with any DXF compliant CAD application on any computer running Vista, XP, Windows 7, Windows 8, or Windows 10. Disk requirement < 2MB.

How is ToleranceCalc licensed?

Permanent activation code is issued for perpetual use of the software by 1 named user on 2 computers (work and home) tied to the MEC ID. In case the computing environment changes, courtesy new activation code is sent to the same named user for no additional cost.
