The User Grids panel controls automatic activation of grid objects and settings for AutoGrid.
Determines if 3ds Max automatically makes grids active upon creation.
Turn on to automatically activate the grid you created.
AutoGrid allows you to automatically create grids on the surface of objects. The task of creating objects that are aligned to other object surfaces has been simplified. Turn on AutoGrid in the Object Type rollout of a command panel. When you turn on AutoGrid, 3ds Max uses the setting in the User Grids dialog for world or object space.
