OK, that sounds like the solution I'm looking for.
It sounds like the answer is to draw the lines in one projection and then
transform it to the other, depending upon which orientation is desired for

You are on quite a different topic here.

OK, thank you. That formula is useful.
I assume that "North" for any projection will be grid North so that a
line drawn at 0° while using a UTM projection will point to grid North
if the drawing is re-projected using an un-projected CRS (where 0° is
true North)?
I wonder if I have that corr
Good Morning,

I appreciate your help, it
The central meridian in each utm zone is oriented directly at true north
(Easting of 500,000 m). The difference in angles when you move east of
west of the meridian is referred to as convergence and the following
link provides 2 formulas for calculating the convergence angles in utm
projection
true north
instead of grid north.

Ah sorry,
I got lost in translation. You are right, I was talking about the magnetic
north, not the geodetic one.
Meanwhile, remembering that all UTM are Transverse Mercator, I don't think
there's a CRS that will solve you question.
I think you need to use some formula to convert the grid north
Alexandre,
I believe that true north is actually a constant oriented towards the North
Pole, i e 90 degrees north latitude. Also where all meridians converge in
the northern hemisphere.
The other North orientations are magnetic north and grid North and these do
vary as you suggested.
I do need t
AFAIK, true bearing differs in time and location because of magnetic
declination. So I don't think there is a such thing as a CRS with true
bearings.
Assuming you are working at regional level, find the magnetic declination
for that region and remove it from your observations. Then draw the azimut
