I have a 3D model in SolidWorks. I want to set some dimensions so that I can put them on a design table and change the design manually via these dimensions. So, I enter a sketch, set a dimension, click the green checkmark, exit sketch... and the dimension disappears. It comes back when I reenter the sketch. How do I get it to stay put? And I checked "Show Feature Dimension", Show Reference Dimensions, Show DimXpert Anootations, and Display Annotations, so it's none of that. Help!
