Thanks for the clarification! I don't think you are right regarding `BRepProj_Projection` - you are confusing projection type with the surface being projected onto. TBH I don't think the proposed...

> `BRepProj_Projection` is great but it doesn't solve one of the central problems with Text on a surface - so I'm looking for some advice here. The problem is that...

Thanks! Note that it should not be needed to use `BRepOffsetAPI_MakeFilling` because you already have the underlying geometry. Here is an example: ```python import OCP w1 = cq.Face.makePlane(2,2).Wires()[0] w2 =...
