TolAnalyst

With TolAnalyst, included with SOLIDWORKS Professional and SOLIDWORKS Premium software, you’ll be able to quickly verify dimensioning and tolerancing schemes to ensure proper fit and function. TolAnalyst GD&T data is read directly from the SOLIDWORKS models.

TolAnalyst eliminates the need for hand calculations and manual entry of dimensions and tolerances.

Maximum/minimum worst-case and RSS results are calculated and a “contributors” list is output to let you know which features and tolerances have the greatest impact on the stack-up. In this way you can loosen tolerances on dimensions that are not important to the stack-up, thereby reducing manufacturing costs.

TolAnalyst Benefits

• Significantly reduces prototyping typically required to test for assembly fit and function and even reveals “worst-case” issues you would not normally find with physical prototyping
• Decreases manufacturing costs by verifying tolerance schemes – allows looser tolerances and less expensive manufacturing techniques where tight tolerances are not needed
• Eliminates the need for hand calculations which can be time consuming and error-prone – TolAnalyst contains a tolerance stack-up analysis engine
• Eliminates the need for manual data entry into a program or spreadsheet because TolAnalyst is seamlessly integrated with DimXpert and automatically extracts DimXpert dimensions and tolerances that are necessary for the stack-up calculation
• Provides graphical and text-based feedback as to which features and tolerances most greatly affect the critical dimension being evaluated – easier for the designer to figure out what tolerances and/or features needs to be modified
• Fast tolerance stack-up calculations, combined with the fact that no manual data entry is required, allows designers to quickly iterate stack-up analyses in order to optimize assembly fit and function
• Solves minimum/maximum “worst-case” tolerance stack-up with respect to position of components in the assembly, not by just merely rebuilding parts at their maximum or minimum tolerances
