Once you've finished your model, you can upload and share it with other users, thanks to the unlimited, free storage space at Google's 3D Warehouse Web site-where you can also grab other people's models (we dropped the Taj Mahal into the center of the Pentagon). Unfortunately, you can't easily push or pull curved surfaces to produce rounded objects, such as a bubble skylight. Similarly, guidelines appear when you cross the cursor over another line, so you can visualize how your object relates to the rest of the scene. SketchUp also highlights the edges and the centers of shapes when the cursor passes over them, making it painless to draw with accuracy. For example, as you draw freehand, with straight lines, or with the pencil tool, SketchUp guesses where you want endpoints to meet and snaps them shut for you. The tools do most of the heavy lifting for you. SketchUp is intuitive just drag around the mouse to draw rectangles, arcs, segments, or circles, then select the Push/Pull tool to extend shapes into the third dimension.

This compact setup leaves maximal space for drawing however, if you wish, you can display up to 12 floating task-specific toolbars, such as those for Drawing, Construction, and Camera. Google SketchUp's no-frills interface consists of a large, central canvas flanked by a single left-hand toolbar containing most of the icons needed to build models, with the rest of the features available from the Main Menu atop the screen.
