The 3DFace command creates mesh or SubD faces that can be standalone or added to an existing mesh or SubD.

A mesh face (left) and a SubD face (right)
  • When meshes or SubDs are pre-selected, the 3DFace command starts in the Append mode.

Command-line options

Output
Mesh

Creates mesh faces.

SubD

Creates SubD faces.

Interpolated (Yes/No)
Yes
No

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.

Append

Selects an existing mesh or SubD to which the new faces will be added.

  • During appending new faces, press ESC to cancel the current face creation. Press ESC one more time to cancel the command.
PolygonType (Triangle/Quad/Ngon)

Specifies to create triangle, quad, or Ngon faces.

  • When PolygonType=Ngon, picking not enough points adds a triangle or quad face.

FromEdge
Yes

Each new face is started by selecting an existing mesh or SubD boundary edge.

Chain (Yes/No)

Create faces along an edge chain. The edge chain can be from an existing mesh or the current creating mesh.

This option is only available when PolygonType= Quad

Example

  1. Click the Append option to select a mesh or SubD.

  2. Set PolygonType=Quad, FromEdge=Yes, Chain=Yes, and Mode=MultipleFaces.

  3. Select a boundary edge of the object.

  4. Pick two points to form the first face.

  5. Pick one point to form the next face and repeat.

  6. Right-click to start a new edge chain.

FromEdgeReset
Yes

Resets FromEdge to No in the next 3DFace command session.

No

Remembers the setting of FromEdge for the next 3DFace command session.

No

Each new face is created by picking points.

InPlane (Yes/No)

Set Yes to define a plane with the first three points and constrain the rest points of the current face on that plane. This option only takes effect when PolygonType=Quad/Ngon.

WeldAngle (Only for Output=Mesh)

The welding tolerance for mesh edges in degrees. Welding applies to edges around new faces. The default angle is 180 degrees that welds all edges.

Mode (SingleFace/MultipleFaces)

Specifies to create only one or more faces in a command session.

Undo

Removes the previous pick.
