| Summary | 0004624: Thickness fails on simple shapes (BRep_API command not done) - regression from 0.19.24267 | ||||
| Description | Thickness operations with Arc or Tangent join types fail on predominantly concave shapes. Message is BRep_API: command not done. This happens for any positive Thickness value. Changing join type to Intersection solves the issue, but does not yield the desired part. This is a potential regression from 0.19.24267 where the issue seemed to be (mostly?) fixed, see reproduction steps below. A Thickness problem in conjunction with OCC 7.5 was previously reported here by user AlStu, with forum discussions here. | ||||
| Steps To Reproduce | Part workbench: Make a simple extrusion from a sketch with concave outer shape. Apply Thickness while selecting the top face. Try different Join types. To test the potential regression from 0.19.24267, open the attached FCstd file. Press F5 to recompute the solution. 0.19.24267 -> Thickness is computed successfully except for the sharp-edged shape. 0.19.24276 -> Thickness (Arc/Tangent join type) fails for 3 out of 4 shapes. Deleting and re-applying thickness yields BRep_API: command not done | ||||
