I can't make a parameter work on a 2D circle. (Constraints are not satisfied)

Hi,

I'm kinda new to Revit and I'm trying to make a symbol for a foundation pole, but I can't get the parameters to work. I tried it with refrence lines but they can't lock and the dimentions that I can get on them don't work. When I change the value of the parameter it gives me a error that says "Constraints are not satisfied". The circle does exits out of 4 parts (Filled region) that are locked together, but this is a copy of one that I made but square and that one does work.

I'll add a screenshot to this post. The parameter "Formaat" is the one that does't work and the "EQ's" are connected the same way. The two parameters on the outside are seperate.

Any idea's on how i can get this to work?

Thanks in advance.

I made this using a Filled Region made up of Quarters, I always user Reference Lines/Planes as i can lock the lines to them to be driven by the Label/Parameter.

I tried this but I can't lock them for some reason. I'll link the file if you want to check it out. Does it maby have to do with the (family) file I made it in?

Corrected my post here untill I found the edit post option. Now I can't delete this one so just ignore it.

You have No Reference Lines used for Driving the Lines/Shapes

Redraw the Filled Region Sketch

Algin the Lines to the the Vertical and Horizontal Reference Planes and then the End nodes of these Lines to the Reference LINES and LOCK

Then draw the Arc using Center-ends Arc this SHOULD automatically lock
