When an ACIS (.sat) file is exported from SolidWorks 2019 with the "Split periodic faces" option OFF, the CAD geometry is incorrect and results in TracePro raytrace errors.
When a CAD program creates a circular surface, the first step is to define an edge. If the edge is revolved twice, once +180 deg, and once -180 deg, the resulting geometry is two semi-circular surfaces. The is applicable to more than circular faces, and the general idea is that geometry that is expected to have a single surface results in that surface being split.
When an ACIS (.sat) file with Split periodic faces is imported into TracePro, the rays can be traced without issue. The problem occurs after the raytrace, when viewing any Analysis Tool what was expected to be a single circular surface. The Irradiance Map can only be viewed for one semi-circle or the other, not both. It is tedious to post-process the data to get the true results for the single surface.
