Drafting - Dimensioning holes (diameter or radius) in parts with curved or spline driven surfaces.

mark_render

In drafting whilst adding radius or diameter dimensions to views the software cannot detect radii and diameters on parts with curved surfaces or spline driven faces using the dimension commands.  A simple example would be a hole in a cylindrical shaft.
Apologies if have have missed something obvious.

Hi Mark,
Onshape doesn't currently support dimensioning these edges. We're aware of this and I'll add you to that improvement.
As a workaround you can add a note to the edge.

DefProc

I see this is already raised as an issue, but I'd already made a representative model here: https://cad.onshape.com/documents/8d1f8d8848e44213ba8a6a98/w/415226b896e34f12be13ebfd/e/79c364ea6d30423388d24258

Hi have these issues been addressed yet?

@andy_morris adding a note would be a workaround if I knew what the radius is but Onshape can't even measure it except as a length. Please add me to the improvement request also.

Can now dimension holes/radii in shafts and other curved surfaces!
Thanks.
