In previous versions, sketches containing multiple closed loops were visually easier to interpret. Features such as Extrude or Revolve would highlight each loop in a distinct colour. Under the Millennium colour scheme, for example, constrained geometry appeared in black, unconstrained geometry in bright green, and fully closed profiles in a khaki-green tone.
Recently, this behaviour no longer seems to function correctly. Although a loop will highlight when hovered over, the underlying sketch geometry remains unchanged in colour. As a result, users must manually hover over each potential loop to determine which profiles are valid.
