SubDLoft
Creates a SubD through selected curves that define the shape.
MultiPipe

SubDExpandEdges
Expands selected SubD edges into faces.
Bevel
Chamfers/fillets SubD edges with specified segments.
InsertEdge (loop)
Inserts edges beside a SubD or mesh edge loop.
InsertEdge (ring)
Inserts edges across a SubD or mesh edge ring.
InsertPoint
Adds vertices and edges to a Mesh or SubD along the picked points on edges.
Append to SubD
Adds triangle, quad, or n-gon faces to an existing SubD.
MergeCoplanarFace
Combines adjacent coplanar faces of a mesh, polysurface, or SubD into a single face.
MergeAllCoplanarFaces
Combines the faces of each planar region on a mesh, polysurface, or SubD into a single face.
Inset
Offsets the edges of selected mesh, SubD, or polysurface faces in a certain distance towards the center of each face.
Stitch
Matches the positions of a pair of mesh/SubD vertices.
Bridge
Creates faces to connect two SubD/Mesh edge chains.
SubDivide
Applies iterations of the Catmull-Clark subdivision to whole Mesh/SubD objects or selected faces.
Rotates a picked SubD edge by marching each end to the next vertex simultaneously. 
SubDSpinEdge
Slide
Moves selected vertices (or vertices of selected edges) along adjacent edges.
PackSubDFaces
Resets a SubD to the default face packing if adding creases or deleting faces breaks the rectangular quad grids.
SetPerFaceColorByFacePack
Changes colors of SubD faces based on the divisions of rectangular quad grids.
RemovePerFaceColors
Clears per-face display colors or rendering materials on polysurfaces or SubDs.
MergeFaces
Merges a connected set of SubD or mesh faces into a single face.
DeleteFaces
Remove faces from a mesh, SubD or Polysurface to create a hole.
Reflect
Makes a SubD symmetrical across a reflection plane and merges both sides into a single SubD.
RemoveSymmetry
Removes the SubD symmetry constraints set by the Reflect and Radiate commands from selected SubDs.
Radiate
Creates a radial-symmetrical SubD with specified segments.
RadiateFind
Identifies the precisely shaped radial symmetry structure in a SubD and then automatically synchronizes editing between the identical regions around the central axis.
Fill
Create SubD/mesh faces from SubD/mesh boundary edges.
ExtrudeMesh
Extrudes mesh faces and boundary edges with different direction modes.
OffsetSubD
Makes a copy of a SubD by moving its vertices towards the normal direction with the specified distance.
QuadRemesh
Uses a unique algorithm to generate manageable polygon meshes, ideal for rendering, animation, CFD, FEA, and reverse-engineering.
RepairSubD
Inspects and deletes damaged components, wire edges, and Non-manifold edges on SubDs.
ToNURBS
