Creating surfaces from linear objects and by
conversion
In
Chapter 4
,
Creating Solids and Surfaces from 2D
we already introduced several
commands for creating procedural surfaces. Let's summarize them:
•
EXTRUDE
(alias
EXT
): This command creates surfaces by applying an ex-
trusion height to open linear objects or closed linear objects if the
MOde
option is set to
SUrface
.
•
REVOLVE
(alias
REV
): This command creates surfaces by rotating open
linear objects, or closed linear objects if the
MOde
option is set to
SUr-
face
, around an axis.
•
SWEEP
: This command creates a surface by extruding an open section,
or closed section if the
MOde
option is set to
SUrface
, along a path.
•
LOFT
: This command creates surfaces from the selection of two or more
open linear cross sections or closed linear cross sections if the
MOde
op-
tion is set to
SUrface
.
