When using Design and computation Manager to label the stationing in plan, I am getting an error message in the Message Center that says "Active Scale Not in Control Point Scale List" So my stationing and/or tick marks are not showing up in the drawing.
This is because the Scale list in the Design and Computation Manger Item you are using does not have the Label Scale you have entered into the Draw Plan & Profile dialog.
So to solve this either enter a scale that matches in the Label Scale section or add the desired scale to the Scale, Increment and Symbology section for the Tick Marks and Tick Mark Stationing.
