---------------
When working in Sketcher and creating an Offset Curve, you enter a value in the "Distance" field and the "Create Dimension" toggle is off. You later go and edit the Offset Curve by double clicking the Offset constraint in the sketch but the dialog does not display the Distance field. How do you edit the distance?
Solution
The logic used in the Offset Curve dialog is that when the user creates a dimensionless offset ("Create Dimension" unchecked), the user will use some other constraint or dimension to drive the offset constraint distance. Therefor we do not allow it to be driven by an offset dimension automatically, unless the user asks for it.
You may edit the existing Offset Curve in the sketch by toggling "Create Dimension" on to display the "Distance" field again. Leaving the "Create Dimension" toggle on will create a "Thickness Dimension" on the sketch, which when edited will bring the user directly to the "Distance" field in the Offset Curve dialog.
