3DFace

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 n-gon 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.

  • 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.

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.
