Here is what I am doing: I am displaying a trihedron when the user selects a face of a shape. To select faces, I open a Local Context and set it to "selecting faces" mode. The trihedron is displayed, but I have been unable to find a way to make something of the trihedron selectable. The shape's faces are still selectable, though.
One thing that almost works is to open a new Local Context, display the trihedron and Activate() selection of faces in the shape. The problem is that face selection is completely screwed up. As long as I do not rotate the view, selection of faces and axes of the trihedron work just fine. When I rotate the view and try to select a different face of the shape, it detects another one. Selection of axes still works as expected, though.
I would like to find a way to make the trihedron's axes selectable (without opening a new Local Context if possible), while also keeping the current selection mode (working as it should).
Thanks in advance.
