Material group
You can apply different material IDs to spline
segments (see Material ID (page 3–969)). You
canthenassignamulti/sub-object material (page
2–1594) to such splines, wh ich appears when the
spline is renderable, or when used for lathing or
extrusion. Be sure to turn on Generate Material
IDs and Use Shape IDs when lofting, lathing or
extruding.
Set ID—L ets you a ssi gn a particular material
ID number to selected segments for use with
multi/sub-object materials and other applications.

Select ID—Selects the segments or splines

Select By Name—This drop-dow n list shows
the names of sub-materials if an object has a
M ulti/Sub-object material assigned to it. Click
the drop arrow and select a material from the list.
The segments or splines that are assigned that
material are selected. If a shape does not have a
M ulti/Sub-Object material assigned to it, the name
list will be unavailable. Likewise, if multiple shapes

While at the Editable Spline (Spline) level, you can
select single and multiple splines within a single
spline object and move, rotate, and scale them
using standard metho ds.
Procedure
To change spline proper ties:
• You change the properties of a spline from Line
to Curve by right-clicking and choosing Line or
Curve from the Tools 1 (upper-left) quadrant
of the quad menu.
Changingthesplinepropertyalsochangesthe
property of all vertices in the spline:
• Choosing Line converts vertices to Corners.
• Choosing Curve converts vertices to Beziers.
