I would like to change the below dimension to be calculated from an equation (be based on global variables):

Expected:

- I right-click on the dimension, and there would be some way.to convert it to this:

Actual:

- I can only derive a sketch dimension from an equation by _creating_ one with such. Thus: 1. delete existing dimension, 2. create a new one using global variables, 3. retype the comments etc. that were lost in this process

Is this so (making this a feature request)?

Suggestion:

When right clicking on an equation-driven dimension, there is "Edit Equation..." menu item. I feel this could be there also for constant dimensions, showing the user that there's a possibility of dimensions to be equation driven. It's best if the context menus are relatively uniform - if the state of a drawing matters for a certain menu to exist or not, it takes some time before we users learn the logic. This seeming randomness is likely one of the biggest hurdles for newcomers to SolidWorks.
