How to scale viewport 3D models fast?

To scale viewport 3D models fast, use your software’s dedicated scaling shortcut (like “S” in Blender or the Scale tool in Maya) and drag the viewport’s scaling gizmo (on-screen handles/arrows) to adjust size quickly. Uniform scaling—hold Shift while dragging—to keep proportions intact, which maintains model accuracy when framing scenes or fitting elements together. Memorize your software’s scaling shortcut: skip menu navigation, just press the key and drag to get the right size instantly.
