Material: Compatibility with Part Design #13344

Open maxwxyz opened 4 weeks ago

maxwxyz commented 4 weeks ago

Is there an existing issue for this?

Problem description

It seems that the material is currently not fully compatible with PartDesign bodies. Test file: PD-mat.zip

Depending on the selection the body has different materials, individual features can have individual materials (is this expected or should the material be on the body?). The problem is, when selecting a face in the 3D view, the last feature of the Part Design body is selected. When trying to apply a material to the entire body by selecting the body in the tree view, the material has no effect or is not applied.

It doesn’t make sense to have different materials for functions inside a body container. The material should be a property of the body container.

Setting the material applies to the whole shape. The appearance can be set independently for each face overriding the appearance of the material. At least that's how it's supposed to work.
