You can create a "spreadsheet" with named cells and refer to those names in your constraints.
For example you could create a cell called "cylinderbore" and have either a static value in it, or a value computed from something else, and you could set a radius constraint to "cylinderbore/2", or "cylinderbore/2 + 0.3" or whatever you want.
(Contrary to what the video implies, you don't have to manually click on each constraint whenever you change your spreadsheet, the global recalculate button will do it.)

There's a demonstration in this 5-minute video: https://www.youtube.com/watch?v=b07qbhYHZbU
