Missing materials and other 3D View issues

[Jordan Stimpson]

I have been working on a project and everything has gone smoothly until today. I got on my project and the 3D view is acting up. Previous material files are gone, for example the brick texture is now just a solid pink and the nice dark flooring and door trim is a gross beige color. Trying to pivot in the 3d view is very difficult and everything disappears but a blue wireframe type view. It does not move in real time so I cannot tell if it is the angle I want until I unclick, and it is often wrong. I am using the educational version and before opening the project it had a pop up saying some aspects of Archicad were unable to be used, but I don't know how to get it back. Would I need to reinstall it?

Regarding the colours, check your View Styles. 

The blue wireframe is AC trying to simplify the view while you pan to get better performance. I think the relevant settings are under Work Environment => Advanced Redraw Options.

If this has only just happened, have you added any high poly objects recently? Are any programs running in the background using up a large amount of your computers RAM?

Sounds like you have lost OpenGL (or Hardware Acceleration I think they call it now).

Maybe it is just a case of restarting your machine.
