Drawing Dimension at an angle

[goodlook]

I am new to this and gone thru the tutorial and other documentation and no luck.

How can I give a dimension at an angle?
Is it possible to select a reference line before the first and second point for the dimension?

Any hot keys or settings?

Thanks

The best way to do this is to dimension between an edge and a point instead of two points. If you're stuck with points, add a short construction line on the first point and constrain it to be perpendicular to your measurement direction. Then dimension from it to the other point.
