Tolerance analysis allows engineers to understand how geometric tolerance stackup and dimensional variation impact design quality and manufacturability. The analysis enables design engineers to identify contributing tolerances that can be modified to achieve higher quality and manufacturability.
A design model is an idealized representation of a part design. Due to manufacturing limitations, physical parts never match the design model. If you want the components of your product to fit together correctly, you’ll want your parts and assemblies to be within certain tolerances or acceptable degrees of variation.
Creo EZ Tolerance Analysis Extension is an extension to Creo Parametric. With Creo EZ Tolerance Analysis Extension you can evaluate the impact of dimensioning on product designs before either prototyping or manufacturing.
