Thanks for the tips. I ended up just reinstalling the program and it seems to have sorted the problem out.

Strange that it started happening though... It was stalling and quitting even if I flipped a single box. It was sketchup 8.0.4810.

Evening all. Sorry for making my first post a question! But Im having a problem which is driving me up the bleeding wall!

Im in the early stages of a design, and I want to flip it. So I do the standard select all>right click>flip along axis. But when I do this Sketchup quits on me. Tried doing it within different windows. The same happens. Do I have to do a reinstall?

The Model is not very big at all. Im an architect student and have worked on large buildings and this hasn't happened before.

Any light on how I could stop this happening would be a massive help.

And sorry if this has already been posted about.

Tom
