Detach—
Copies selected splines to a new spline
object, and deletes them from the currently
selected spline if Copy is clear.
•
Reorient—The spline being detached is moved
and rotated so that its creation local coordinate
system is aligned w ith the creation local
coordinate system of the selected spline.
•
Co py—When selected, copies rather than moves
thesplineasitisdetached.
Explode—Breaks up any selected splines by
converting each segment to a separate spline
orobject. Thisisatime-savingequivalentof
using Detach on each segment in the spline in
succession.
You can choose to explode to splines or objects. If
you choose Object, you’re prompted for a name;
each successive new spline object uses that name
appended with an incremented two-digit number.

Material group
You c an apply different material IDs (see
material ID (page 3–969)) to splines in shapes
containing multiple splines. You can then assign
a multi/sub-object material (page 2–1594) to
such shapes, which appears when the spline is
renderable, or when used for lathing or extrusion.
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
corresponding to the Material ID specified in

specify an ID, then click the Select ID button.
Select By Name—This drop-down list shows
the names of sub-materials if an object has a
M ulti/Sub-object material assigned to it. Click
the drop a rrow and select a material from the list.
The seg ments or splines that are assig ned that
material are selected. If a shape does not have a
M ulti/Sub-Object material assigned to it, the name

Clear S election—When turned on, selecting a new
ID or material name, forces a deselection of any
previously selected segments or splines. If turned
off, selections are cumulative s o new ID or material
name selections add to a previous selection set of
segments or splines. Default=on.
