You can use Split Face on any non-family instance. The Split Face tool splits the selected face of the element; it does not change the structure of the element. After splitting the face, you can use the Paint tool to apply a different material to this section of face. See Applying a Material to the Face of an Element.
Example
A wall with a split face (around the window) before painting
A wall with a split face (around the window) after painting

- Sketch the face area to split. Note: The sketch must be in a closed loop inside the face or an open loop that ends on the boundary of the face.
Example

Tip: You can split the face of a column. However, if you plan to have multiple instances of the split-face column in your project, create the column in the Family Editor and apply the split there.
