I would like to be able to use the pencil tool to draw lines angled exactly 2 units to the right for every 1 unit down, at angles of about 27 degrees from vertical or horizontal.
The straight-line rule using shift-ctrl draws in increments of 15 degrees. Is there a way to change this default so shift-ctrl draws at my desired angle?
To achieve the same result, I have also drawn cartesian and near-isometric grids to shift-draw straight lines over. This requires some care and it would be nice to draw them more quickly. I would also appreciate any other suggestions for drawing these lines.
