It is sometimes very difficult to work out how a model has been created when working on other people’s 3D models.
We need more aids to teach us how someone else has created the 3D model you are now working on.
One aid could be when a sketch has been projected from another sketch, you could hover over and it would indicate the original point/line/sketch/part it was projected from?
How are things sketches created, where do they come from, what references do they use, how were they drawn?
Maybe all dimensions within the actual sketch could be one colour but dimensions to other geometry such as to the origin or to other sketches/featues/workplanes could be in different colours?
Maybe there should be a way to select something in the sketch that will highlight in the feature tree (or somewhere) the workplane it was created on or the surface it was created on, etc?
