Wrapper object, select the Wrapper object in the
list window, open the Modifier stack, and select

Update group
The items in this group determine when the
projection for the compound object is recalculated.
Because complex compound objects can slow
performance, you can use these options to avoid
constant calculation.
•
Always—The object is updated constantly.
•
When R ender ing—The object is recalculated
only when the scene is rendered.
•
Manually—Activates the Update button for
manual recalculation.
Update—Recalculates the projection.
Hide Wra p-To Object—When on, hides the Wrap-To
object.
Display group
Determines whether the shape operands are
displayed.
• Result—Displays the result of the operat ion.
•
Oper ands —Displays the operands.

The Connect compound object lets you connect
two or more objects between "holes" in their
surfaces. To do this, you delete faces in each object
to create one or more holes in their surfaces,
position them so that the holes face one another,
and then apply Connect.
Left: Before connect
Right: After connect
Note: Connect is not suited to NURBS objects,
because they convert into many separate meshes
instead of one big mesh. The workaround is
simple: apply a Weld modifier to the NURBS
object(thusconvertingittoameshandzippingup
its seams) before using it as part of a connect.
Connect generates the b est mapping coordinates it
can for the bridges between the various holes in the
meshes. While some ideal cases, such as a cylinder
above another cylinder, can generate good UVW
map interpolations, most cases cannot. You’ll need
to apply mapping to the bridge faces with a UVW
Map modifier (page 1–922).
