But Sigmetrix are experts at 3D tolerance analysis – Why introduce a stand-alone 1D product?
We know not everyone needs, or believes they need, a solution as powerful as CETOL 6σ, so this new solution should be of great interest to Mechanical Designers and Engineers who are involved in CAD-modeling activities. It automates many of the common but time-consuming and often error-prone tasks required for 1D stack up analyses. It provides a more complete picture than traditionally obtained from a spreadsheet calculation and can alert the user in many situations when the tolerance stack up may not be 1D in nature.
Will it work with my CAD system?
YES! EZtol works with files from most major CAD systems, and it does not utilize the CAD license to work on the model.
Supported File Types
|CAD system||Supported Versions|
|CATIA V5||V5_6R2021 and earlier|
|NX||NX V11.0 to NX 12.0 and 1953|
|SOLIDWORKS||SOLIDWORKS 97 up to 2021|
What about Creo and Inventor?
Sigmetrix has partnered with Autodesk and PTC to provide the same powerful 1D tolerance analysis capabilities found in the stand-alone EZtol product as integrated solutions for both Autodesk’s Inventor and PTC’s Creo.

Does EZtol work with STEP or other neutral file formats?
No, EZtol currently only works with the CAD native files for CATIA, NX, and SOLIDWORKS. EZtol does not work with neutral files such as STEP.
The reason for not supporting STEP or other neutral files is that EZtol is intended to be used during the design process to guide designers and engineers in understanding the sources of variation in their models and choosing appropriate tolerances that meet their quality goals. As such it is most convenient to work with the models in their native format. Users of EZtol don’t need to worry about exporting their models to a format compatible with EZtol since the native files are already supported.
If you have received a set of models in a neutral format such as STEP and want to perform a stackup analysis with EZtol you would first need to import those files into CATIA, NX, or SOLIDWORKS and then run EZtol on the files after they have been saved in the native CAD format.
