This is a tip that I just saw from Lynn Allen’s blog [found here]and thought that I would share it here as well.
Imagine trying to dimension something that doesn’t have parallel or perpendicular pick points. So when you pick the 2 points for the dimension, it will normally create the dimension so that it is perpendicular to those 2 points.
With the command DIMROTATED you can now specify the angle that you want the dimension to be perpendicular to.
Here’s how:
- DIMROTATED <enter>
- Specify the angle that you want the dimension to be perpendicular to by picking 2 points
- Pick the 2 points to start the dimension
- Place the dimension
AutoCAD Tips 
this is a great new feature! I typically change my UCS to match the direction that I want and then do the linear dimension, rather than aligned. In fact, I will continue to do this where I am doing a lot of dimensions of this type, but for just one this is a nice feature.
I was pretty stoked when I saw this tip as well. It seems like such a basic need that I am amazed that this tool is only available as a command and not in a toolbar or ribbon panel…
Me too. I’d love to make a button for this command.
