We’re sure you’ve noticed that SketchUp will snap to specific inferences as you draw with certain tools. The Arc tool snaps to a half-circle proportion. The Rectangle tool snaps to square proportions as well as the Golden Section (Golden Ratio). A dotted line with a Golden Section tool tip will appear when you’re in a position to create a Golden Section. Try this for yourself by clicking once to start drawing a rectangle – hover slowly – and look for SketchUp to snap to those proportions.
