# 3DFace
## 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](https://docs.mcneel.com/rhino/8/help/en-us/commands/3dface.htm#Append) mode.
### Command-line options
#### **Output**
* **Mesh:** Creates mesh faces.
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.
