ShapeMerge creates a
compound object consisting of a mesh object and one or more shapes.
The shapes are either embedded in the mesh, altering the edge and
face patterns, or subtracted from the mesh.
the lettering, a text shape, with the mesh that models the tire.
To create a ShapeMerge object:
- Create a mesh object and one or more
- Align the shapes in the viewport so they
can be projected toward the surface of the mesh object.
- Select the mesh object,
then click the ShapeMerge button.
- Click Pick Shape, and then click the
The geometry of the surface
of the mesh object is altered to embed a pattern matching that of
the selected shape.
Pick Operand rollout
- Pick Shape
Click this button, and then
click the shape you want to embed in the mesh object. The shape
is projected onto the mesh object in the direction of the shape's
local negative Z axis. For example, if you create a box, and then
create a shape in the Top viewport, the shape is projected onto
the top of the box. You can repeat this process to add shapes, and
the shapes can be projected in different directions. Simply click
Pick Shape again, and then pick another shape.
Lets you specify how
the shape is transferred to the compound object. It can be transferred
either as a
a copy, an
or moved, in which case the original shape is not left behind.
- Operands list
Lists all operands in
the compound object. The first operand is the mesh object, and any
number of shape-based operands can follow.
- Delete Shape
Remove selected shapes from
the compound object.
- Extract Operand
Extracts a copy or an instance
of the selected operand. Choose an operand in the list window to
enable this button.

Merges the shape with the

When Invert is off, the shape is a hole in the mesh object. When Invert
is on, the shape is solid and the mesh is missing. When you're using
Merge, Invert reverses the sub-object mesh selection. As an example,
if you merge a circle shape and apply a Face Extrude, the circular
area is extruded when Invert is off, and all but the circular area
is extruded when Invert is on.
Output Sub-Mesh Selection
Provides options that
let you specify what selection level is passed up the Stack. The
ShapeMerge object stores all selection levels; that is, it stores
the vertices, faces, and edges of the merged shape with the object.
(If you apply a Mesh Select modifier and go to the various sub-object
levels, you'll see that the merged shape is selected.) Thus, if
you follow the ShapeMerge with a modifier that acts on a specific
level, such as Face Extrude, that modifier will work properly.
If you apply a modifier
that can work on any selection level, such as Volume Select or XForm,
the options will specify which selection level is passed to that
modifier. Although you can use a
Select modifier to specify a selection
level, the Mesh Select modifier considers the selection only at
frame 0. If you've animated the shape operand, that animation will
be passed up the Stack for all frames only by using the Output Sub-Mesh
