296 Chapter 5: Creating Geometry
When this option is chosen, new vertices that
overlap are automatically welded.
•
Bezier—New vertices will have bezier tangency .
•
B ezier Cor ner—New vertices will have bezier
corner tangency.
Cr e ate L i ne—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
1–270). To exit line creation, right-click or click
to turn off Create Line.
Break—Splits a spline at the selected vertex or
vertices. S elect one or more vertices and then
click Break to create the split. There are now two
superimposed non-connected vertices for ever y
previous one, allowing the once-joined segment
ends to be moved away from each 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 a n object, the materials of the
two objects are combined in the following way:
• If the object 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 inherits the material of the
object being attached.
• If b oth objects have m aterials, the resulting new
material is a multi/sub-object material (page
2–1594) that encompasses the input materials.
A dialog appears offering three methods of
combining the objects’ materials and material
IDs. For more informa tion, see Attach Options
Dialog (page 1–1018).
Attached shapes lose their identity 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 e dits, modifiers, and animation applied
to the attached shape are frozen at the current
frame.
Reorient—When on, rotates the attached spline so
that its creation loca l coordinate system is aligned
with the creation local coordinate system of the
selected spline.
Attach Mul t.—Click this button to display the
Attach Multiple dialog, which contains a list of all
other shapes in t he scene. Select the shape s you
want to attach to the current editable spline, then
click OK.
Cr o s s Se ctio n —Creates a spline cage out of
cross-sectional shapes. Click C ross 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 S ection
modifier, but here you can determine the order
of the cross sections. Spline c age tangency can b e
defined by choosing Linear, Bezier, Bezier Corner
or Smooth in New Vertex Type group.
