I have O-Ring grooves of different sizes. some of these grooves are in Outer diameter and some are in Inner diameter of my parts. So I plan to create a macro which has sketch for the different groove sizes and when I run the macro it has to ask for dia. size ( or select the dia) and the distance of groove from one of the edge (to make sketch fully defined). Please some one help me. I donot haveToolbox installed. Thanks in advance.
