SubD

Nine groups, left to right.

Convert and display

• To SubDTurns a mesh or surface into a SubD.
• Display ModeSwitches between the smooth and the box view.

Primitives

• Single FaceOne SubD face from four corners.
• PlaneA flat SubD plane.
• BoxA SubD box.
• SphereA SubD sphere.
• EllipsoidA SubD ellipsoid.
• CylinderA SubD cylinder.
• ConeA SubD cone.
• Truncated ConeA SubD cone with its tip cut off.
• TorusA SubD ring.

From curves

• Sweep 1Sweeps a profile along one rail as SubD.
• Sweep 2Sweeps a profile along two rails as SubD.
• MultipipeBuilds a SubD pipe network around a curve skeleton.
• OffsetOffsets a SubD, optionally solidifying it.
• ReflectAdds a mirror plane so both halves stay in sync.
• Remove SymmetryDrops the symmetry constraint, freeing both halves.
• RevolveRevolves a profile into a SubD.
• LoftLofts a SubD through profile curves.
• Extract Control PolygonDraws the control cage as a mesh.
• ExtrudeExtrudes a curve or face into a SubD.
• Extract SurfacePulls a face out as its own surface.
• RadiateRepeats geometry radially around an axis.

Add geometry

• Insert PointAdds a vertex to a face.
• Insert EdgeInserts an edge loop.
• Expand EdgesWidens an edge into a band of faces.
• AppendAdds a face onto a border edge.
• SubdivisionSplits every face, raising the density.
• InsetInsets a face inside its own border.

Edit

• BevelBevels the edges you pick.
• Remove CreaseSoftens an edge marked sharp.
• CreaseMarks an edge as sharp.
• Merge FacesMerges the faces you pick into one.
• SmoothRelaxes the shape, evening out the vertices.
• Slide EdgeSlides an edge along the surface.
• Spin EdgeRotates a shared edge to the other diagonal.
• Merge Coplanar FaceMerges faces lying in the same plane.
• Align VerticesLines up the vertices you pick.
• Soft TransformMoves a vertex and lets the neighbours follow.

Close and repair

• StitchSews two SubD borders together.
• Fill HoleCloses an open border with new faces.
• BridgeConnects two openings with a tube of faces.
• Delete FaceRemoves the faces you pick.

Remesh

• Quad MeshRebuilds the shape as an even quad grid.
• Repair MeshFixes what stops a mesh becoming a SubD.
• Pack SubD FacesPacks the faces into texture space.
• Set Per Face Color By Face PackColours each face by its pack, to read the layout.

Selection

• SubD EdgeSelects edges.
• SubD FaceSelects faces.
• SubD VertexSelects vertices.
• SubD ObjectSelects the whole SubD.
• Loop EdgeSelects the edge loop through a picked edge.
• Loop FaceSelects the face loop through a picked face.
• Edge RingSelects the ring of parallel edges.
• SubD EdgesSelects every edge of the SubD.
• Toggle Face Edge VertexCycles the selection filter.
• Select SubDSelects every SubD in the file.
• Faces To BoundaryGrows a face selection out to a border.
• BrushPaints a selection with the cursor.
• Named SelectionsSaves a selection to recall later.
• Make SubD FriendlyRebuilds a curve or surface so SubD tools accept it.

Convert out

• To NURBSConverts the SubD back to NURBS surfaces.
