Unable to create dimcurvelength in detail view

Previous version of Rhino (5) I was able to add a dimcurvelength dimension to a detail view drawing. Rhino 7.3.21039.11201 it is unable to select the curve to dimension. The command works fine in model space.

Hi David -

Thanks for reporting that issue. I’ve written it up as item RH-63149 for a developer to take a look.
