Sigmetrix Enhances EZtol to Read Product Manufacturing Information (PMI)

Sigmetrix releases a new version of EZtol for Siemens NX and Dassault Systemes CATIA

MCKINNEY, Texas – April 14, 2021 – Sigmetrix, experts in mechanical variation management, announced their release of EZtol 2.0 for NX and CATIA. The new version will offer updated UI and enhanced features to determine the impact of part and assembly variation on the fit and performance of products.

EZtol v2.0 is a significant upgrade to the capabilities of Sigmetrix’s 1D tolerance analysis tool. “We’re excited about EZtol 2.0’s ability to read PMI data – tolerance information defined with the CAD part files,” said Stephen Werst, Director of Customer Success & Product Strategy at Sigmetrix. “This enhancement makes an already fast workflow for analyzing all of your 1D stackups even faster.”

In addition to the new ability for EZtol to read PMI, this release also has a much smaller download and installed application size as well as a new, simpler interface.
