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

* When meshes or SubDs are pre-selected, the 3DFace command starts in the [Append](https://docs.mcneel.com/rhino/8/help/en-us/commands/3dface.htm#Append) mode.

### Command-line options

#### **Output**

* **Mesh:** Creates mesh faces.

* **SubD:** Creates SubD faces.

**Interpolated (Yes/No)**

Conceptually, this is the difference between what the [Curve](https://docs.mcneel.com/rhino/8/help/en-us/commands/curve.htm) and [InterpCrv](https://docs.mcneel.com/rhino/8/help/en-us/commands/interpcrv.htm) 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.
