I am trying to integrate the use of BRepOffsetAPI_MakeOffsetShape , but it fails most of the times even in simple shapes. The attached example is a box sliced with a plane (not parallel to the coordinate planes) and I want to offset with 1mm. I tried all the combinations, but with no luck. What is wrong in this case? Why it fails. If I have an answer at least for the reason. Can someone thicken this inside with any value?
If someone can help me, I will appreciate a lot.
