Windows- Plan display trouble

[Anonymous]

Hello there,
(see pic)
got these black thick curved lines which I thought could be fixed on window or wall settings but nothing seems to work. they are ArchiCad-10 library (not Smart Parts). Sometimes curved parallel lines, other times a curved shadow-like on wall exterior.

will appreciate any pointers as to the cause/solution.

Cheers !

It looks like the linetype for either the sills or the uncut or overhead wall linetype. Could also be a fill or a background color for the window's fill. If nothing of that, it may be a bug in the library part.

thanks Thomas,
you may be right about a bug in AC-10 library part, since I've tried every possible option/setting and yet...

many thanks (tacks ?) anyway,
Cedric
