Roughness PMI Recognition with SolidWorks

aPriori 2026 R1 SP1 adds support for extracting surface roughness PMI (product and manufacturing Information) from files saved with SolidWorks 2026 or later. aPriori reads Ra (arithmetic mean roughness, SolidWorks Surface Finish Field 1) and Rz (mean roughness depth, Field 6). After costing, extracted roughness values are visible in the Tolerance and Finishing Operations section.

To use this feature, ensure roughness annotations in SolidWorks are semantically defined; each annotation must be explicitly associated with at least one surface in the model. Annotations not linked to specific surfaces cannot be read. SolidWorks 2026 or later is required; earlier versions are not supported for roughness PMI extraction.
