Other than color, how can I tell that a sketch is fully defined?

Sometimes in a large sketch, there is a small entity that is not constrained.  It can be a rogue point, or two endpoints that don't quite coincide.  Without going over every sketch element zoomed in close, I can't tell if there is a small bit of blue amidst the black.

In SolidWorks, there is a "Fully Constrained" message so I know I did everything right and don't have to check for unconstrained elements.  Is there some similar diagnostic in Onshape?

There is not. However, it is good practice to keep sketches as simple as possible - this makes your models more robust and resilient to change and makes your sketches easier to troubleshoot should something go wrong.

Hi folks.

In the past we've asked for the sketch name in the feature tree to be blue for "unconstrained" sketches, black for "fully constrained" and red for "in-error".  That would fix this problem once and for all

Should you care to add your vote the IR is here:-
