'08/20/05 Edited the macro for the new engine. Brian
'Rev1  2/3/05 ID and OD have been tested and seem to be working  fine... The Right to left should be working as well.. we will know more when Steve gets done with me ;)   
'Rev1.1 2/7/05 There was a bug that would make a bad cut if a large angle was called Fixed with "sometrig"
