This has probably been around for awhile, but I just noticed it today: You cannot add a jog point to a dimension attached to a 2D entity. It works fine if the dimension is to a 3D model entity, but not for a drawing sketch entity.
In this case it is a regular part drawing where there is an area specified to be clean and free from surface irregularities. A sketched circle identifies the size of the area. Dimensions were a bit cluttered and it would have been more legible with a different placement with a jog to clearly see the arrow placement. But it wasn't possible with a 2D sketched entity.
I did find two work arounds. Using a note driven by the dimension, and placing a sketch for the area within the 3D model itself. Buth will allow jog dimensions, but requires extra work to complete.
I do not believe that dimensioning options should be any different between 2D and 3d entities, unless it's something that just isn't possible to dimension. (I can't think of any examples.)
