By Corners
-
Used to construct a B-spline surface by defining its four corner points, which may be non-planar.
|
|
-
By Points
-
(3D only) Used to place or construct a free-form B-spline surface.

-
Network of Curves
-
(3D only) Used to construct a B-spline surface that is transformed between elements of a network.
|
|
-
By Image
-
Used to create a B-spline surface from a raster image.
|
|
-
Loft
-
(3D only) Used to construct a B-spline surface that is transformed between section elements (lines, line strings, arcs, ellipses, complex chains, complex shapes, B-spline curves, or the edges of a surface).
|
|
-
Loft by Vertices
-
Used to construct a surface between the vertices of two profiles (or groups of profiles).

|
-
Loft Transition
-
Used to create a Smart Surface transition from a rectangular to a circular section.
|
|
-
Extrude
-
(3D only) Used to create a surface generated by linearly extruding a profile element (line, line string, arc, ellipse, text, multi-line, complex chain, or complex shape, edge of a surface or solid element, or B-spline curve) a defined distance.
|
|
- a tubular surface extrusion along a path.
- a surface by extruding a profile element (line, line string, arc, ellipse, complex chain, complex shape, or B-spline curve) along a path.
|
|
-
Sweep
-
(3D only) Used to create a Smart Surface by sweeping one or two section profile curves along one or two trace curves.
|
|
-
Revolve
-
Used to create a surface of revolution — a complex 3D element that is generated by rotating a profile element (line, line string, arc, ellipse, shape, complex chain, complex shape, or B-spline curve) about an axis of revolution.
