NO curves when opening the file?

[toofuerte]

I am having a problem that started about a week ago, when I turn on the computer and open a drawing it comes up with lines and no curves so the door symbols for example are weird looking and several other curves are not showing up right. But when i close the file and reopen it the file comes up right. Has this come up anywhere or has anyone else had this happen.

I have no idea what may be causing your problem, but the PDF is certainly interesting. Is this really what you are seeing in ArchiCAD? It looks more like art than architecture. What does the correct drawing look like?

sounds like a graphics card problem to me. But that is about all i can offer in help
