Editable Spline 289
Parameters rollout
Lengt h—Controls the height of the vertical web
of the wide flange.
Width—Controls the w idth of the horizontal
flanges crossing the wide flange.
Thick ness—Controls the thickness of the web and
flanges.
Co rner Ra dius —Controls the radius of the four
interior corners between the vertical web and
horizontal flanges.
Note: Take care when adjusting these settings.
There are no constraining relationships between
them. Therefore, it’s possible to set a r adius
(Corner Radius) that is g reater than the leng t h of
the web or width of the flanges.

Editable Spline provides controls for manipulating
an object as a spline object and at three sub-object
levels: vertex, segment, and spline.
The functions in Editable Spline are the same as
those in the Edit Spline modifier (page 1–680).The
exceptionisthatwhenyouconvertanexisting
spline shape to an editable spline, the creation
parameters are no longer accessible or animatable.
However, the spline’s interpolation settings (step
settings) remain available in the editable spline.
When a spline-editing operation (typically,
moving a segment or vertex) causes end vertices
to overlap, you can use the Weld command to
weld the overlapping vertices together or the Fuse
command if you want the two overlap ping vertices
tooccupythesamepointinspacebutremain
separate vertices.
Note: Welding coincident vertices is controlled by
the End Point Auto-Welding feature.
