Splines—Are a combination of one or more
connected segments.
Named Selections group
Co py—Places a n amed selection into the copy
buffer.
Pas te—Pastes a named selection from the copy
buffer.
Lock H a ndl es —Normally you can transform t he
tangent handles of only one vertex at a time, even
when multiple vertices are selected. Use the Lock
HandlescontrolstotransformmultipleBezierand
Bezier Corner handles simultaneously.
Alik e—As you drag the handle of an incoming
vector , all incoming vectors of the selected vertices
move simultaneously. Likewise, mov ing the
outgoing tangent handle on one vertex moves the
outgoing tangent handle for all selected vertices.
All—Anyhandleyoumoveaffectsallhandlesin
the selection, regardless of whether they’re broken.
This option is a lso useful w hen working w ith a
single Bezier Corner ver tex when you want to
move both handles.
Shi f t +click a handle to "break" the t angent
and move each hand le independently. T he Alike
option must be chosen to break the tangent.
Area S election—Lets you select automatically all
vertices within a specific radius of the vertex you
click. At the Vertex sub-object level, turn on Area
Selection, and then set the radius with the spinner
to the right of the Area Selection check box. This
is useful when moving vertices that have been
created using Connect Copy or Cross Sec tion
button.
Segment End—Select a vertex by clicking a
segment.InVertexsub-object,turnonandselecta
segment close to the vertex that you want selected.
Use this when there are a number of coincident
vertices and you want to select a vertex on a
specific segment. The cursor changes to a cross
when it is over a segment. By holding down the
Ctrl key you can add to the selection.
Select By—Selectsverticesontheselectedspline
or segment. First s elect a spline or segment in
sub-object spline or seg ment, then tur n on vertex
sub-object and click Selec t By and cho ose Spline
or Segment. All the vertices on the selected spline
or segm ent are selected. You can then edit the
vertices.
Display group
Show V er tex Number s—When on, the program
displays vertex numbers next to the selected
spline’s vertices at any sub-object level.
Selected Only—When on, the vertex number or
numbers appear only next to selected vertices.
Soft Selection
For information on the Soft Selection rollout
settings, see Soft Selection Rollout (page 1–963).
Selection Info
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 selected.
At the Vertex and Segment sub-object levels,
if one sub-object is selected, the text gives the
identification numbers of the current spline (with
respect to t he current object) and of the current
selected sub-object. Each spline object conta ins
a spline number 1; if it contains m ore than one
spline, the subsequent splines are numbered
consecutively higher.
When a single spline is selected at the Spline
sub-object level, the first line displays the
identification number of the selected spline and
whetherit’sopenorclosed,andthesecondline
