sketch dimensions

In Solidworks you can use dimensions to drive other dimensions. The process is you use "=" then click on the dimension you want to reference, you can add a formula if you want as well. Eg: = "D1@Sketch1"*2" (this makes this dimensions 2 times bigger than D1) How do you do this in OnShape (this is a feature we use regularly…

Is any option to add tolerances (or notes) to the sketch dimension?

Is there any way to create sketch constraints that reflect "greater than / less than" or "is a multiple of"? Two scenarios: * I have two holes that need to be at least 1" apart. They can be farther apart, but they can't be closer. * A spacer can be any multiple of 0.5", but making a 1.3172" spacer is prohibitive Right now…
