What card do you have?[/quote]

Intel HD Graphics 3000

And turning of the hardware acceleration seems to take of most of it, but you were right, it is REALLY slow without it!

I have been working on my house model and now I'm getting errant objects (lines, icons, etc) on the screen as I try to use a tool. they are not part of the file, but I must quit to get rid of them. Is this a memory or video card problem? It didn't appear until my file got larger, so small files seems to work fine without this aberration.

Also sometimes when I open the file, everything looks normal, I can select any tool, but none of them function.

Any help is greatly appreciated. Running SketchUp 8.0.1 on Windows 7 Home Premium version 6.1

Thank you Gaieus!

That did the trick. I then drew lines to define the portion that protruded and deleted everything above.

Thanks again - you have saved me numerous hours of trial and error

Hi there - I'm new to this forum and am just learning SketchUp. I've viewed the training videos so I have the basics. I've already watched several on building a 3D model of a house and it appears there are many ways to tackle the design. However, I've run across a design feature in my house that I've not seen discussed: the house has a flat roof (slopes about 2 degrees front to back) and the walls do the same. The front wall is about 9' while the back wall is about 8' and all the side and interior walls follow this slope. Any suggestions on where this might have been discussed or does anyone have any suggestions about how to go about producing the plan when only the east-west running walls are rectangles?

Oh - I've also just installed the HouseBuilder plugin which does this nicely, but haven't yet figured out to hang drywall on all that framing!

Thanks in advance!
