Latest EZtol Software Streamlines 1-D Tolerance Stackups

Sigmetrix, experts in mechanical variation management, has announced the release of EZtol v2.3. The new version offers numerous enhancements that make it even easier to create 1-D tolerance stackup analyses for NX, CATIA, and SOLIDWORKS models.

New Simple Fit Check analysis type – A new streamlined workflow allows users to check the fit between two features of size (pin/hole, slab/slot, pin/slot) with a few simple clicks.

New Show Stackup tool – A new command called Show Stackup will temporarily reposition components to the locations defined by their mating features. This is useful for verifying the stackup is defined as expected.

Allow use of current section view as annotation plane – When defining a new stackup, if the model has an active section view that is parallel to the stackup direction, it now possible to place the stackup dimensions on the section view plane.

Improved visibility management of supplemental geometry – Hiding and showing of supplemental geometry items (planes, axes, curves, points, coordinate systems) is more intuitive.

Improved performance while working with larger models – Actions such as creating stackups and showing or hiding of model items are faster.

EZtol is a 1-Dimensional tolerance stackup analysis program designed to assist with understanding the impact on assembly-level requirements of the accumulation of part-level dimensional variation and part-to-part assembly variation.

Many engineers use spreadsheets to analyze tolerance stackups for their designs. EZtol was created to provide a better way to do stackups by operating directly on the CAD models while utilizing the PMI in those models. “We’re focused on making EZtol fast and easy to use,” said Raphael Nascimento, Product Manager for EZtol. “With EZtol v2.3, we’ve added several enhancements that demonstrate this commitment. Two examples are the new Show Stackup tool, which helps users visually confirm that the stackup is set up correctly, and the new Simple Fit Check, which allows users to check the fit between two features of size with only a few clicks.”
