Expressions: Broken references and Fx icon on sketcher dimensions should show with "broken reference" color (orange like with projected geometry)

Is there an existing issue for this?

• I have searched the existing issues

Problem description

When you use values from a VarSet you will see the Fx indicator in blue, so you know your dimension has a formula.

I had duplicated a Part and didnt realize my VarSet was inside the Part, and also got duplicated, and then of course deleted the extra one, and went to correct the broken references.

I noticed the now broken formulas do not have the blue indicator:

Broken dimensions in sketches maybe could use the same "broken edge" color that broken projected geometry uses, and the fX icon could also be that orange to consistently indicate that something is broken on your constraint.
