SketchUp for Web is optimized to be used with a 3-button mouse by default. If you're using a device with a multitouch trackpad, you can switch the input device to 'Trackpad' in App Settings. With trackpad navigation you can use multitouch gestures like pinch-to-zoom or orbit/pan with a two-finger swipe. To switch to trackpad navigation follow these steps:
- Open the Menu () and click App Settings ().
- Click Navigation.
- Under Choose Device select Trackpad next to Device.
- Assign Orbit, Pan, or Zoom as your two-finger swipe gesture.
You can also fine tune the performance of the Zoom, Orbit, and Pan actions using Invert Direction and Device Sensitivity. These settings only adjust navigation operations and do not impact the Zoom, Orbit, or Pan tools.
