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:
-
Right-click an edge with the Select tool.
-
Choose Divide from the context menu that pops up.
-
Type the number of segments you’d like and press Enter.
To resize your whole model based on one known measurement:
-
Select the Tape Measure tool.
-
Press Ctrl (Option on a Mac) until you don’t see a + next to your cursor.
-
Measure a distance; click once to start measuring, and again to stop.
-
Type a dimension for the distance you just measured and press Enter.
-
Click Yes in the dialog box that pops up.
To set up your own keyboard shortcuts:
-
Choose Window→Preferences (File→Preferences on the Mac).
-
Click the Shortcuts panel.
