Patch Select Modifier 753
Edge—Selects an edge beneath the cursor;
region selection selects multiple edges within the
region.
Patch—Selects a patch beneath the cursor;
region selection selects multiple patches within
the region.
El ement—Selects all contiguous faces in an
object; region selection selects the same.
Select By Vertex—Selects any sub-objects at the
current level that use a vertex you click. Applies
to all sub-object levels except Vertex. Also work s
with Region Select.
Ignore Backfaces—Selects only those edges,
patches, or elements whose nor mals make them
visible in the viewport. When turned off (the
default), select ion includes all sub-objects,
regardless of the direction of their normals.
Note: ThestateoftheBackfaceCullsettinginthe
Display panel doesn’t affect sub-object selection.
Thus, if Ignore Backfacing is tur ned off, you can
select sub-objects even if you can’t see them.
Note: The state of the Ignore Backfaces check bo x
also affects edge selection at the Edge sub-object
select ion level.

Named S election Sets group
Thesefunctionsareprimarilyforcopying
named selection sets (page 1–83) of sub-objects
between sim ilar objects, and between comp arable
modifiers and editable objects. For example, you
canapplyapatchselectmodifiertoasphere,
create a named selection set of edges, and then
copy the selection to a different sphere that’s been
conv erted to an editable patch object. You can
even copy the selection set to a different type of
object, because 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 I D numbers vary from
object to object, the results of copying named
selection sets between different objects can 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 w hen the set is pasted.
