This integration is built as a SolidWorks Add-In for SolidWorks 2014 and 2015.
Using both SolidWorks and PTC Mathcad Prime's API, this AddIn lets users quickly drive PTC Mathcad Prime input variables from SolidWorks' CAD model parameters. Users can also map PTC Mathcad Prime output results back to the SolidWorks CAD model. This creates the bi-directional nature of the integration.
Note: PTC Mathcad/SolidWorks Integration is not officially supported by PTC.
