It would be really cool if you could automatically segment the Dimension tool into equal parts. I remember in SketchUp that you can split a line into multiple points and it's very helpful when designing.
In Bluebeam, I have a light fixture layout on a plan that needs to be adjusted. I'd like to have 3 lights equally centered across a dimension… but to scale, draw a line and do the math to make this look good it takes a lot of time.
