Door Schedule Formula Help

[kdaugherty7]

I've been trying to find some info regarding using formulas in our door schedules, but I am having trouble finding exactly what I need/want.

I would basically like to automate some things in our door schedule, one thing I am having trouble with is our "Door Details" column. We have wall types set up and I would like Revit to fill out the "Door Details" column based on the wall type the door is placed in. For example, a door in "Wall Type A" will ALWAYS have "Door Detail 1". Can I have Revit complete this task so that I don't have to manually enter this info? Is this possible with formulas? If so, can someone point me to some documentation on how to properly use/write formulas? Any help would be appreciated.

Many Thanks,

-Kyle

Add a shared parameter - text - to the project as well as to the door families that you are using. I would think that you would want it to be Instance based. Associate it to Doors in the project or Project Template. 

You may now add the required value to the door family, or to the properties of the door instances. These values will populate the schedule. Also - if you have a value added to one door instance and you click on a blank field for another door - the entered values will show up as a drop down. Less typing.

A wall hosted family is smart enough to detect the geometry but not other intelligent properties of its host.  So, if you can associate the Door detail parameter with the wall thickness via a formula.  With that said, it is hardly practical because in reality you can have different wall types with the same thickness (for instance, a 4" stud + 5/8" gwb wall can be non-rated, one hour fire partition, or one hour fire barrier).

Another approach is using Dynamo to read the host wall parameter value and write to the door's parameter.  Then use that directly or for a formula to generate the Door Detail for each door.
