Archicad 15 curtain wall - unexplainable visible lines

[Anonymous]

Dear forum readers,

I have come across something totally new and unexplainable. I am working on a school project and all was peachy. After editing some panels and frames on the curtain wall disaster happened. These new lines appeared. I got no clue on getting rid of them. Anyone had this problem before? maybe knows how to solve this? I might be a bit over dramatic.

EDIT: oh yeah, it doenst show up in 3d, its only visible in the plans.
EDIT2: also its not all plans, only the second story.

Thanks in advance,

Alper

For clarification this is the 3d model of the curtain wall.

And while i am at it. I couldnt figure out how to make shadows colored(glass is colored). Al though i have found out that replacing the glass in artlantis for glass and changing the color in artlantis, it does project colored shadows.
