I try to get the face selected in an opencascade viewer but i don't know how to do this. When I load a step I add the shape in the context and I activate the face selection like this :
This woks, only the face are selectable in the viewer. But finally, when I pick the face I don't kown how to get the information of this face.
The action to pick the face works because the the face is highlight in the viewer but when I check the context the selected face is empty, idem for the owner. Someone know the solution ?
