Seriously, I can't figure out how ArcGIS Pro decides which direction to draw a line. When I draw a parallel (or perpendicular) line, I press "P" (or "E"), then "D" for distance enter in a value, then ArcGIS Pro always draws the line in the opposite direction I want. Watch the video. I put in positive 1000 varas twice, but each time it draws the line in a different direction. Why? I always end up having to do this two or three times for each polygon because I have no idea where the line is going to go.
