grid plane

A grid plane is an area that cannot be edited, but that you can place objects on. If you're going to create custom terrains, you need to remove the grid plane(s) in your project before you can do this. To select a grid plane, make sure you're in Selections Mode, then click on the grid. It will now have a yellow border. To remove the selected grid plane, press the Delete key.
