thanks much for reading and atleast willing to help. I know I am asking a lot, but your family approach seemed very cumbersome to do (not your fault, revit issue) the leaders etc , adding to the file manually etc. That is why I was thinking the API approach. Can anyone atleast point to me where I can find details on the API etc. AS I said We just recently purchased our copies and have made the commitment to switch. I just need to come up with a relatively equal ease of use on the Keynoting/CONDOCs since we use them very extensively.
