Place Room Automatically using Revit API

I want to use Place Room Automatically using revit api but currently not able to see any example for it

Look for the Document.NewRoom() method. (This is the Document Creation object, not the regular Document object). You have options for:

• NewRoom(Phase) - create an unplaced room in a particular phase.
• NewRoom(Level, UV) - create a room on a particular level at an X,Y point
• NewRoom(Room, PlanCircuit) - create a new room or place an unplaced room into a "PlanCircuit", which is an identified space that can contain a room within the geometry.

Rooms exist within a single phase, make sure you're aware of what phase it is created in.
