Aha, thanks Kirk. That's why my lines are not as I intended. This
probably affects making the lines with the Shape Tool.
Yes, it seems to draw in grid north, angle_main reports in True DD. The
map is 26907, UTM 7N.
I calculated the difference between as drawn and as reported and used
that to change the input figure. It works OK, not exact as the
convergence varies with longitude, I believe.
Thanks Kirk . . . .

Hi Spingfield.
I use a little routine and the core if it is:
main_angle($geometry) which you can use in field calculator.
Note this will give you the azimuth in relation to grid north for the
coordinate system you are using. For projections, you will need to
lookup or calculate convergence to get the adjustment to true north.

Hello,
I need to put the line direction (azimuth) into a line label. Some
searching has not come up with anything.
Is there a way? Thanks very much . . . .
