Using Maya 6: :headbang: I would like to create a simple mitred cornice on the top of a wardrobe. Cornices in rooms work beautifully - I just let the extruded sections run into each other at the corner and forget about any overlength at the back of the scene. Cornices on furniture meet with the sharp edge visible ( the opposite of the cornice on a ceiling). Is there any way of trimming off the excess at the meeting point? Thanks for any suggestions.
