Hi
I'm using Archicad 17, and i'm having a problem with my guide lines. The Instant Guide Lines During Input just disappeared, i'm tired of reading forums and posts but I just can't find the solution. I start drawing a line, and to make it parallel to X, I have to press Shift, the instant guide line don't appear. I think I checked every options but them refuse to appear. I'm a student, in the last year of Architecture and I need this madly.
