Troubleshooting 3D navigation
The model is out of view or hard to find
Click Fit to Screen in the viewer toolbar to reset the camera to show the full model. If Plane Cut is active, it may be slicing the model out of frame, click it again to toggle it off.
Rotation feels locked or wrong
If the camera won't rotate freely, check whether Walk Controls (first-person mode) is active, click the icon again to exit it. You can also use the ViewCube (FRONT/BACK/TOP etc.) to snap to a standard orientation, or use the Roll –90 / Roll +90 buttons if the model is tilted unexpectedly.
The camera perspective looks off
Open Space Settings and check the Camera Type. Switch between Perspective and Orthographic to see which suits your model. See Change camera type.
The model looks washed out or recolored
Transparent Parts or Recolor Model may be active. Click them in the canvas context menu or viewer toolbar to toggle them off.
Mouse input isn't responding
Click inside the canvas area first to give it focus, then try again.
