Hi, I am following the steps in Mirroring the Mounting Bosses. In Step.2, it asks us to point to the orange point shown in the illustration. Then, in Step 2, it asks us to select the Front plane and check. I cannot find the orange point shown in the illustration. Where is it? If I just click somewhere near where it is supposed to be, SW gives me "Current combinations of references and constraints are not valid", "Rebuild Errors Plane is not allowed with general surface. I guess the reason is that I chose a surface rather than the orange point.
