AutoGrid lets you automatically
create, merge, or import objects on the surface of other objects
by generating and activating a temporary construction plane based
on normals of the face that you click. This serves as a more efficient
way of stacking objects as you create them, rather than building
objects and then aligning them as a separate step.
AutoGrid used to position
the second block on top of the first
You can use objects within
an XRef scene as reference when AutoGrid is on.
NoteIf the Smooth check
box is turned on in the Parameters rollout of a parametric object,
the construction plane is placed tangent to the face of the surface
implied by any smoothing present on the surface, not the actual
face of the surface.
Example: To create a box aligned to another
object using a temporary construction grid:
- Create or load a scene containing an
object to which you want to align a new box.
- On the Create
panel with (Geometry) active Standard Primitives Object Type rollout,
- Turn on AutoGrid.
- Merge the object you want aligned.
- Move your cursor over the object to which
you want to orient the box you are about to create.
The cursor includes an X,Y,Z tripod to help
you orient the position of the new object. As you move over the
object, the cursor aligns the Z axis to the surface normal.
- When the orientation is as you want it,
click and use the standard drag-release-move-click method to create
the box. The box will be created on the designated surface.
When you click, a temporary, automatic grid
is created, and the newly created object is aligned to that grid.
Object Type rollout
AutoGrid is available only
after you select an object button (such as Box). When you turn AutoGrid
on, the cursor includes an axis tripod to help you orient the grid.
Before clicking and as you position the cursor over a visible mesh
object, the cursor jumps to the nearest point on that surface. The tripod's
X and Y axes form a plane tangent to the object surface (forming
an implied construction grid), and the Z axis is perpendicular to
After creating the object, 3ds Max places
it on the temporary construction grid. When creating an object,
if the cursor isn't over another object, 3ds Max places the object
on the current active grid.
When you create an
object that requires multiple clicks, AutoGrid applies only to the
first click. So, for instance, if you want to create a
that snaps to the faces of a sphere,
then open the
And Snap Settings dialog
and turn on Face.
NoteTo make the grid
permanent, hold down the Alt key before
you click. The grid becomes active and 3ds Max turns AutoGrid
