When working with Lumion, and in particular, when organizing our 3D world, and arranging and adjusting the 3D models, we might find the possibility of locking the 3D model's position to be useful. This helps us to avoid selecting and unintentionally moving other, already placed 3D models.

Select the Lock position... option.
Click on the On option to lock, or the Off option to unlock, as you can see in the following screenshot:
