Radius in layout

I am trying to determine and dimension a 2-point arc curve in Layout.

I usually have a reference point in SketchUp, but not this time…

This is what I see. There is an inference to the center.

I didn’t realize that it was so easy.

Are you usually using length dimension for the radius? I thought I might do that and change the start and end points.

Thank you.
