Is there a way to create a resultant dimension in Revit? One which can have a parameter assigned to it? Digital Project allows resultant dimensions. It would be nice if Revit did...

Can you clarify what you actually trying to achieve as I'm not familiar with a "resultant dimension"... You can place a dimension on most things in Revit and add a parameter and use that parameter to control further parameters...?

Right. I've used 'resultant' dimensions as you described. This goes back to my geometry problem to which you've already replied. Digital Project allows you to place dimension strings to items and allows you to assign a parameter dimension to it. For example, if you snap too many dimensions to a sketch in revit, you receive a message which tells you something like 'locking this dimension will overconstrain the sketch.' Digital Project allows you to place a dimension, add a parameter to it, and then check a 'resultant dimension' option. I'm guessing revit has no such feature.

what the purpose of checking the 'resultant dimension' option, other than that it sounds no different than Revit.

Thing of it as geometry without formulas. You can draw two legs of a triangle and not know what the other leg is. Perhaps that third leg is driving your geometry. In the background, the computer/program is computating all of these relationships and assigning values to elements based on the input. If I have something like a line which begins at a random point within a circle and terminates at some point along that radius, there is a length for that line which is not obvious to me. I can snap a dimension onto the line and see what the actual distance is, but in order to use that same information (the length of the line) I will need to create a formula which tells me the info. In short, a resultant dimension would just tell me whatever measurement I am looking for. I can snap a dimension onto something, assign it as a resultant dimension, and use it as parametric input. It's a dimension that results from input, but is also used to create and drive additional geometry. Nonetheless, I was fairly certain Revit didn't have a feature like this and wanted to confirm it. I think that has been done.

Hello!
I´m also looking for a way to summarize determined dimensions. For example, I want to know how many meters I have in a project but the project is in autocad and I want to import it to revit and just add the dimensions and in some way make a "schedule" of the dimensions I added and sum all of them.
Can anyone help me?

Your question isn't clear but here is a shot at an answer....
Import the CAD, then trace over it with a simple wall. Don't dimension. Just schedule the wall and add up the lengths in the schedule. NOTE - Pay attention to wall location (center / inside face / outside face) because that will affect wall length.

I caný start to draw walls, the project is enormous. That´s why I want to summarize the lenght of the dimension lines I´m creating.
Like a schedule of dimension lines.

reporting parameters! Yeah.
oh wait- instance based only?!?
half-way there.
