This might not be a API specific question, but can I have a table on a drawing that is linked to values in a part so if I update the table it will update the part's dimensions?

Also with that regard, I have some extrude cuts that 90% of the time have no problems cutting through a part. Some of the times though it leaves small "ears" or little chunks of material hanging in space. Now my extrude keeps all the bodies and messes up a later defined process to make the part into a sheet metal part. What is the code in API to always select body 1 on an extrude cut?

Thanks,

Adam
