Named Selection Sets group
These functions are primarily for copying
named selection sets (page 1–85) of sub-objects
between similar objects, and between comparable
modifiers and editable objects. For example, you
canapplyapatchselectmodifiertoasphere,
create a named selection set of edges, and then
copy the select ion to a different sphere that’s been
converted to an editable patch object. You can
even copy the selection set to a different type of
object, b ecause the selection is identified by the
entities’ ID numbers.
The standard procedure is to create a selection set,
name it, and then use Copy to duplicate it into the
copy buffer. Next, select a different object and/or
modifier,gotothesamesub-objectlevelasyou
were in when you copied the set, and click Paste.
Note: Because sub-object ID numbers vary from
object to object, the results of copying named
selection sets be tween different objects c an be
unexpected. For example, if the buffered set
contains only entities numbered higher than any
that exist in the target object, no entities will be
selected when the set is pasted.
Co py—Places a named selection into the copy
buffer.
Pas t e—Pastes a named selection from the copy
buffer.
Select Open Edges—Selectsalledgeswithonlyone
face. In most objects, this will show you where
missing patches exist. Available only at the Edge
sub-object level.

about the current selection. If 0 or more than one
sub-object is selected, the text gives the number
and ty p e selected. If one sub-object is selected, the

item.

instead of a spline shape or NURBS
curve path.
To use the PatchDeform modifier, apply it to the
object you want to deform, click the Pick Patch
button, and then select a patch object. Deform
