Input in degrees, minutes, seconds-how do I?

yes you can they are called whole circle bearings.

type units
set angle to deg/min/sec


lisp also attached Bearing-Distance.lsp
not sure who wrote it, but I see CAB over at the swamp made some edits.

hope its of use to you.

I'm sure every funky geometry teacher has their own pet name for it, but in the surveying profession and in AutoCAD Civil 3D or any other professional software what you're referring to is an Azimuth. We use bearings in the US, but I started out using azimuths in the military back in the '70's. It was the NATO standard. Typically measured from North, but measured from South by some in the Southern hemisphere.

Jonathan are you trying to draw or annotate lines using azimuths? Rather than converting I'd use whichever one was provided to draw the lines. I've written a routine to label lines and curves using bearings. Haven't seen an azimuth in 35 years.

Not that it's any better than the advice already given here, but I just thought I would point the OP at a tutorial I wrote up a while back, showing how to enter survey data using vanilla AutoCAD and no add-ons.

In the surveying profession in England it's called the 'whole circle bearing' and what your referring to is called a 'quadrant bearing'.
No need to get your knickers in a twist.

Good to know. Do they have a 'Line by whole circle command' in Civil 3D for you guys or is it 'Line by Azimuth'? Do your drawings look like Jonathan's? It looked like one from the US and he didn't offer any more clues in his profile. A descriptive profile helps in knowing what a posters needs are. The angles we used in Europe in the '70's were azimuths measured in mils with 6400 mils in a circle.

We don't have a cadastral system over here, so rarely produce drawings like Jonathan's. Instead we use a general boundary system which means the boundary is hereish..
Ah mils, I'd never heard of them - http://en.wikipedia.org/wiki/Angular_mil
