Create unlocked "measurement" dimensions on a Sketch
Some users may want to measure geometry on their Sketch by placing dimensions that aren't constraints.
The Sketch SmartDimension command by default creates locked constraint dimensions.
If you want unlocked dimensions, start the SmartDimension command.
Then uncheck the "Locked" toggle in the Property Browser.
After that you can place unlocked "measurement" dimensions.
You will have to uncheck "Locked" once per IronCAD session.
