Dimension won't pick control points from Intersect Crv

I made a clipping plane intersect an object with a record history on to use in a detail view in layout. The polyline created is working well, and I can even select it from the detail view, but when I try to use dimension, I wasn’t able to pick the control points from the polyline. Someone know why?

Hi Marcelo - I see that here on Rhino 6 but this appears to have been fixed for Rhino 7.
