Straight Lines in ArtRage 3

질문 : How do I draw straight lines?
답 : Hold down the CTRL key (or Command key in Macs) to draw a straight line.
Holding down the SHIFT key will allow you to rotate the direction you draw in, in 15 degree steps.
(holding down SHIFT alone changes the size of the tool, with the pen movement - up to increase size, down to decrease)
