There is a trick for drawing a line from one side of the sectional (one
airport) to the other side (an airport on toe opposite side) whan planning
a route, but I cannot remember it and cannot find it in any of my reference
material. can anyone help me out?

If you are drawing a course at a certain magnetic heading:

Use a separate piece of paper where the course line is going to go off
the edge of the sectional. Draw a line on it, l;ay that paper with
the line over the last line of latitude on that side and mark it with
a few of the longitude tick marks near where the course line is going
to go.

Then draw the course line and continue it onto the separate sheet of
paper.

Turn over the sectional, line up the separate piece of paper with the
first latitude line on that side, matching up the tick marks. Then
using the line on the paper as a guide, continue drawing the course
line,

If you are are drawing a couse from airport to airport, use the same
trick to index the paper to the chart and mark the location of the
target airport on the paper. Then lline things up on the other side
and draw the course to the airport on that side. Then follow the first
instructions to draw the line on the other side.
