    “It's not necessary to calculate azimuth and draw a line toward the body.
    You can work directly with azimuth angle Z and omit the azimuth line.
    Begin by orienting the edge of the protractor east - west. Suppose the
    body is west of the meridian and you're in the northern hemisphere. Turn
    protractor counterclockwise by the azimuth angle. Move it to the assumed
    position, then shift it toward or away according to your calculated
    intercept. Now draw the LOP.

    This is simple with a square protractor, though it may not be possible
    with other drawing instruments.”

    Bypassing the drawing of the azimuth line is the main purpose of the T-Plotter. There are articles about it on my blog, and my YouTube channel has demo videos about its various types:
    Basic
    Blank
    Protractor
