<p>Hello Everyone,<br>
<br>
Thanks very much for the suggestions. The main_angle option seem
to do the trick.<br>
<br>
I didn't try the Python code. Not familiar with that side of
things although it is probably simple enough. Could not find the
recipe for adding it to the plug-in list, which I presume is where
it is supposed to go.<br>
<br>
Thanks again, very helpful…<br>

<p>Hi Springfield:</p>

<p>Sure it would , I have attached my little convergence tool.
Just create a point in the area where you want to know the
convergence at let her rip. The vary last column is the
convergence in minutes. So, depending on what side of the
central meridian of your coordinate system you are, it will
either be negative or positive. SO, I just used it yesterday for
and area that is east of the meridian, UTM easting > 500,000,
therefore the resulting convergence was 22 minutes, which need
to be subtracted from the grid north value to obtain true
north. It is not a sophisticated workflow, but I only require
it intermittently.</p>
<p>I usually use NRCAN magnetic declination calculator (online) to
verify the magnetic declination for the day. But it seems to be
offline. I convert everything to magnetic for field work and
then there are no mistakes due to declination calculations and
settings.</p>
<p>Have fun</p>

<p>Aha, thanks Kirk. That's why my lines are not as I
intended. This probably affects making the lines with the
Shape Tool.</p>
<p>Yes, it seems to draw in grid north, angle_main reports in
True DD. The map is 26907, UTM 7N.</p>
<p>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.</p>
<p>Thanks Kirk . . . .<br>

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