Selection Rollout (Polymesh) 1025
Note:
You can convert sub-object selections in
three different ways with the use of the
Ctrl and
Shi f t keys:
•Toconvertthecurrentselectiontoadifferent
sub-object level, clicking a sub-object button
on the Selection rollout with
Ct rl held down.
This selects all sub-objects at the new level that
touch the previous selection. For example,
if you select a vertex, and then
Ct rl +click
the Polygon button, all polygons that use that
vertex are selected.
To convert the selection to only sub-objects
all of whose source components are originally
selected, hold down both
Ct rl and Shif t
as you change the level. For example, if you
convert a vertex selection to a polygon selection
with
Ctrl+S hi ft +click, the resultant selection
includes only those polygons all of whose
vertices were orig inally selected.
To convert the selection to only sub-objects
that border the selection, hold down
Shif t as
you change the level. The selection conversion
is inclusive, meaning:
When you convert faces, the resulting
selection of edges or vertices all belong to
selected faces that bordered unselected faces.
Only the edges or vertices that bordered
unselected faces are selected.

When y ou convert vertices to faces, the
resulting selection of faces had al l of their
vertices selected and bordered unselected
faces. When you convert vertices to edges,
the resulting selection contains only edges
all of whose vertices were previously sele cted
andonlyedgesoffacesthatdidnothaveall
vertices selected; that is, of faces around the
border of the vertex selection.

When you convert edges to faces, the
resulting selection of faces had some but
not all of their edges selected, and were
next to faces w ith no edges selected. When
you convert edges to vert ices, the resulting
ver tices are on previously selected edges,

were selected.

Conversion commands are also available from the
quad menu.
