HideandBindgroup
Hide—Hides selected vertices and any connected
segments. Select one or more vertices, and then
click Hide.
Unhide All —Displays any hidden sub-objects.
Bind—Lets you c reate bound vertices (page
3–1013)
. Click Bind, and then drag from any end
vertex in the current selection to any segment in
thecurrentselectionexcepttheoneconnectedto
the vertex. Before dragging, when the cursor is
over an eligible vertex, it changes to a + cursor.
While drag ging, a dashed line connects the vertex
and the current mouse position, and when the
mouse cursor is over an eligible segment, it
changes to a "connect" symbol. When you release
over an eligible segment, the vertex jumps to the
center of the segment and is bound to it.
Bind is useful for connecting splines when building
a spline network for u se with the
Surface modifier
(page 1–833)
.
Unbind—Lets you disconnect bound vertices
(page 3–1013)
from the segments to w hich they’re
attached. Select one or more bound vertices, and
the click the Unbind button.
Delete—Deletes the selected vertex or vertices,
along with one attached segment per deleted
vertex.
Display group
Show selected segs—When on, any selected
segments are high lighted in red at the Vertex
sub-object level. When off (the default), selected
segments are highlighted only at the Segment
sub-object level.

A segment is the portion of a spline curve between
two of its vertices. While at the Editable Spline
(Segment) level, you can select single and multiple
segments and move, rotate, scale or clone them
using st a ndard methods.
Procedure
To change s egment pr oper t ies:
1.
Select an editable spline segment, and then
right-click.
2. On the Tools 1 (upper-left) quadrant of the
quad menu, choose Line or Curve.
The effect of changing segment properties
varies according to the type of vertices at the
segment end.
• Cornerverticesalwaysresultinline
segments regardless of the segment property.
• Smooth vertices can support both line or
cur ve segment properties.
• Bezier and Bezier Corner vertices apply their
tangent handles only to curve segments.
Tangent handles are ignored by line
segments.
