SubD From Object |
The ToSubD command converts supported object types into SubD objects.
Input
Mesh, Extrusion, Surface, Sub-surface
Command-line options
UseMesh
ControlPoints
Turns mesh vertices into SubD control points (left).
Location
Turns mesh vertices into SubD surface points (right).
Conceptually, this is the difference between what the Curve and InterpCrv commands do. The Curve command turns input points into the curve's control points. The InterpCrv command creates a curve to pass the input points.
MeshCreases
Specifies whether unwelded mesh edges (red) will be turned into creased edges.
MeshCorners
Specifies whether the boundary corner vertex of a quad mesh face will be creased or smoothed.
UseSurface
ControlPoints
Turns NURBS surface control points into SubD control points.
Use this option if you are doing "Class A" modeling and need to join separate SubDs into a single SubD.
Location
The output SubD has the best fit to the input NURBS surface. Extra faces might be inserted.
SurfaceCorners
Specifies whether NURBS surface corners will turn into creased or smooth SubD vertices.
DeleteInput
Deletes (Yes) or keeps (No) the input object.
- When a surface is SubD friendly (left), the SubD will match to the input surface shape.
- Trims of a surface or sub-surface will be lost in the SubD.
- Sub-surfaces of a polysurface will be converted individually.
- Non-manifold mesh edges and related faces will be removed.
