I would like to know if there is a possible way to add calculation point for all the doors in my Revit project with dynamo programming. How we do control the properties of family in project environment. Thanks in Advance
You cannot add an actual calculation point with Dynamo, but you can create points that act as Room Calculation points. Check out this post: Obtain Space for Pipes
I wouldn’t say it is not possible. I imagine you can do the following,
- Get Family document from family type
- modify parameters in family document
- Reload in the project.

My bad, I assumed doors didn’t have a Room Calculation Point 
No problem. That made me do a double take because I assumed they do. 
Thank you all for the support.
