Editable Mesh Surface 987
Ignore V isible Edges—
This is enabled when the
Polygon face selection method is chosen. When
Ignore Visible Edges is off ( the default), and you
click a face, the selection will not go beyond the
visible edges no matter what the setting of the
Planar Thresh spinner. When this is on, face
selection ignores the visible edges, using the Planar
Thresh setting as a guide.
Generally,ifyouwanttoselecta"facet"(acoplanar
collection of faces), you set the Planar Threshold
to 1.0. On the other hand, if you’re trying to select
acurvedsurface,increasethevaluedependingon
the amount of curvature.
Planar Thresh—(Planar Threshold) Specifies the
threshold va lue that determines which faces are
coplanar for Polygon face selection.
Show Normals—When on, the program displays
normals (page 3–1074) in the viewports. Normals
are displayed as blue lines.
ShownormalsisnotavailableinEdgemode.
Scale—Specifies the size of the normals display ed
in the view port when Show is on.
Delete Isolated Ver tices—When on, 3ds Max
eliminates any isolated vertices when you delete
a contiguous selection of sub-objects. When
off, deleting a select ion leaves all vertices intact.
Not Available at the Ver tex sub-object level.
Default=on.
An isolated vertex is one that has no associated face
geometry. For example, if Delete Isolated Vertices
is off and you delete a rectangular sele ction of four
polygons, a ll clustered about a single central point,
the point remains, suspended in space.
Hide—Hides any selected sub-objects. Edges and
entire objects cannot b e hidden.
Tip: The Select Invert command on the 3ds Max
Edit menu is useful for selecting faces to hide.
Select the faces you want to focus on, choose Edit
> Select Invert, then click the Hide button.
Unhide A ll—Restores any hidden objects to
visibility. Hidden vertices can be unhidden only
when in Vertex sub-object level.
Named S e lections
Co py—Places a named selection into the copy
buffer.
Pas t e—Pastes a named selection from the copy
buffer.

Selec tion Information
At the bottom of the Selection rollout is a text
display giving information about the current
selection. If 0 or more than one sub-object is
selected, the text gives the number and type
selected. If one sub-object is selected, the text gives
the identification number and type of the selected
item.
Note: When the current sub-object level is Polygon
or Element, selection information is given in faces.
Soft Se lection rollout
Soft Selection controls affect the action of
sub-object Move, Rotate, and Scale functions.
When these are on, 3ds Max applies a spline curve
deformation to unselected vertices surrounding
the transformed selected sub-object. This provides
a magnet-like effect with a sphere of influence
around the transformation.

its sub-objects. For specific information, click any
