SolidWorks includes TolAnalyst™ tolerance analysis tool that automatically checks the effects of tolerances on parts and assemblies to ensure consistent fit of components and to verify tolerancing schemes before the product goes into production. The tolerance analysis can be rerun instantly if a dimensioning or tolerancing change is made, enabling you to get to an optimized tolerancing scheme more quickly.
TolAnalyst provides automated tolerance analysis studies to:
-
Assess min/max tolerances
-
Perform root-sum-squared (RSS) tolerance analysis
-
List contributing features and tolerances categorized by percent impact
Make changes to dimension and tolerancing schemes, and instantly run an updated tolerance analysis to see the impact of your changes.
