Editable Spline (Object) 291
• B ezi er Corner —New vertices will have bezier
corner tangency.
Cr e ate Li n e —Adds more splines to the selected
spline. These lines are separate spline sub-objects;
create them in the same way as the
line spline
(page 1–265)
. To exit line creation, right-click or
click to turn off Create Line.
Break—Splits a spline at the selec ted vertex or
vertices. Select one or more vertices and then
click Break to create the split. There are now two
superimposed non-connected vertices for every
previous one, allowing the once-joined segment
ends to be moved away from e ach other.
Attach—Lets you attach another spline in the scene
to the selected spline. Click the object you want to
attach to the currently selected spline object. The
object you’re attaching to must also b e a spline.
Unattached splines (left) and attached splines (right)
When you attach an object, the materials of the
two objects are combined i n the following way:
• If the objec t being attached does not have a
material assigned, it inherits the material of the
object it is being attached to.
• Likewise if the object you’re attaching to doesn’t
have a material, it in herits the material of the
object being attached.
• If both objects have materials, the resulting new
material is a
multi/sub-object material (page
2–1403)
that encompasses the input materials.
A dialog appears offering three methods of
combining the objects’ materials and material
IDs. For more information, see
Attach Options
Dialog (page 1–1009)
.
Attached shapes lose their ident ity as individual
shapes, with the following results:
• The attached shape loses all access to its
creation parameters. For example, once you
attach a circle to a square you cannot go back
and change the radius parameter of the circle.
• The modifier stack of the attached shape is
collapsed.
Any edits, modifiers, and animation applied
to the attached shape are frozen at the current
frame.
Reorient—When on, rotates the attached spline s o
that its creation loca l coordinate system is aligned
with the creation lo cal coordinate system of the
selected spline.
Attach M ult.—Click this button to display the
Attach Multiple dialog, which contains a list of all
other shapes in the scene. Select the shapes you
want to attach to the current editable spline, then
click OK.
Cr o s s S e cti on —Creates a spline cage out of
cross-sectional shapes. Click Cross Sec tion,
select one shape then a second shape, splines are
created joining the first shape with the second.
Continue clicking shapes to add them to the cage.
This functionality is similar to the Cross Section
modifier, but here you can determine the order
of the cross sec tions. Spline cage tangency c an be
defined by choosing Linear, Bezier, Bezier Corner
or Smooth in New Vertex Type group.
