How to use RIR Add Aligned Dimension?

Hi All,

Can anyone guide me how to use RIR add aligned dimension??

I understand the input V and L, which is the view and line on how much to stretch.

I am stuck at R, which is labelled as References.

In my case i wish to snap to control point (annotation) made as a family

I have tried Element Geometry which only return a sphere in Grasshopper

@jia.yeap you can check the following link in this regard. In case of families it’s recommended to use predefined planes and use them as references for dimensions.

Can you share this family file ?

@jia.yeap In your case something like this will work

Thanks for your help!
I tried and still were not able to add the dimension. I also tried to simplify and still no success:

@afshin_shafa you need list of references to create a dimesnion.

I tried but I just don’t know how to find a line from a circle:

can you share the revit file you are using

test.gh (21.7 KB)

I’m creating the rectangle and circle with GH
