You guys have always been able to help me in the past. I am hoping that you can this time also. I am writing a macro, and I am having a hard time with one of the subs. What I want is to get the value of 3 preselected dimension, store them in some variable, do some calculations with them, and then write the results to a specified custom property in SolidWorks. Can someone either give me some code to do this, or at least point me in the right direction. Thnx for the help.
