i am having trouble with guidelines. when i did the tutorials for the program i would draw a wall and a guidelines for the wall would come up automatically based on the actual wall. now however, the guidelines are based on the origin of the drawing. in other words, if i want to draw a orthogonal wall i have to hold down the shift key because the guideline always points to the origin(0,0,0) of the drawing. i am sure this is a simple setting i have to turn off, but for the life of me i can't find it. can anyone tell me where this is located?
