Hi guys, So I'm starting as an absolute beginner, have DraftSight 2018 free download. Am trying to draw two 45 degree lines of equal length from one starting point, basically like a kid would draw a house roof. My instructions say once you have Polar line showing 45 degrees type line distance and press Enter, eg. 3 Enter, every time I do this the line jumps to either vertical or horizontal. What am I doing wrong? Help!!!
