This type of surface cannot be tapered with standard taper. Only planes, cylinders and cones can be tapered. For cylinders and cones, the axis needs to be parallel to the draft direction. (The face normal of the red face in the example is not parallel to the cylinder axis).
• Possible Solutions:
◦ Use a draft direction parallel to the cylinder and cone axis (in the above example, the bottom face was used).
◦ Use the Advanced Taper command that allows tapering of freeform geometry and cylinders and cones whose axis are not parallel to the draft direction.
Problem #2:
The face normal of a selected face is parallel to the draft direction. This face cannot be tapered since it would vanish by definition.
• Possible Solutions #2:
◦ Remove the problem faces from the selection list.
