This tip shows how you can leverage driven dimensions to make something symmetrical. For example, in the below sketch you may want the rectangles to be spaced equally from each other.
Add dimensions as shown below, and notice that when you add the second dimension between the rectangles, it tells you it is overconstrained (it adds a reference dimension) because of the overall dimension and the dimensions of the rectangles.
The sketch should look like the sketch below.
To make both spaces between rectangles equal, select the nondriven dimension (in this case .208), then the driven dimension (in this case .042). Both dimensions update to .125.
Now change the overall dimension to 2.5” and notice how the spacing between the rectangles updates.
