<<It's my pleasure to announce the launch of Google SketchUp 7. If you've been putting off getting familiar with Google Earth's 3D modeling "other half", now's the time to do something about it. After all, nothing makes a nicer holiday gift for your spouse than a 3D model of your dwelling or dream dwelling. Well, almost nothing.

[...]
Edges now split other edges where they cross, automatically. Modeling in SketchUp is more intuitive now.
The inferencing system (SketchUp's colored points and guide lines that help you draw in 3D) is clearer and more consistent than ever.
When you need help using a tool, click the "?" icon at the bottom of your modeling window; the Instructor panel pops up to give you more information.>>

Being kind of repetitive, but no Linux support. Just posted about it in the Sketchup forum

Is this a way to force Linux users to install Wine? Wine is founded by Google

"Part-funded", not "founded".
