By Plane

Used to construct a rectangular Bspline surface from defined corner points, or from averaging multiple defined points.



By Edges

(3D only) Used to construct a Bspline surface that has up to 6 elements (lines, line strings, shapes, arcs, curves, Bspline curves, complex chains, and complex shapes) as edges.



By Corners

Used to construct a Bspline surface by defining its four corner points, which may be nonplanar.



By Points

(3D only) Used to place or construct a freeform Bspline surface.



Network of Curves

(3D only) Used to construct a Bspline surface that is transformed between elements of a network.



By Image

Used to create a Bspline surface from a raster image.



Loft

(3D only) Used to construct a Bspline surface that is transformed between section elements (lines, line strings, arcs, ellipses, complex chains, complex shapes, Bspline 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, multiline, complex chain, or complex shape, edge of a surface or solid element, or Bspline 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 Bspline 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 Bspline curve) about an axis of revolution.



Helix

(3D only) Used to construct a helicalshaped Bspline surface by sweeping a section profile curve along a helix curve.



Slab

(3D only) Used to place an extruded surface with a rectangular crosssection.



Dome

(3D only) Used to place a dome shaped surface, which is a part of a sphere.



Cylinder

(3D only) Used to place a cylindrical surface.



Torus

(3D only) Used to place a torus surface (a donutshaped surface).



Cone

(3D only) Used to place a cone surface.



Elliptical Cone

(3D only) Used to place an elliptical cone surface, which is a transition surface between two ellipses.
