Creating a 3-D model takes time, but SketchUp makes it accessible and easy when compared to high-end modeling programs. As you create your models in SketchUp, you'll come to appreciate the following timesaving techniques.

To divide an edge into a number of shorter edges:

  1. Right-click an edge with the Select tool.

  2. Choose Divide from the context menu that pops up.

  3. Type the number of segments you'd like and press Enter.

To resize your whole model based on one known measurement:

  1. Select the Tape Measure tool.

  2. Press Ctrl (Option on a Mac) until you don't see a + next to your cursor.

  3. Measure a distance; click once to start measuring, and again to stop.

  4. Type a dimension for the distance you just measured and press Enter.

  5. Click Yes in the dialog box that pops up.

To set up your own keyboard shortcuts:

  1. Choose Window→Preferences (File→Preferences on the Mac).

  2. Click the Shortcuts panel.
