Defines a coordinate system using three points . Returns a frame with origin as the origin, the X+ axis along the vector from origin to xloc, and the Y+ axis from origin to yloc.
Frames define coordinate systems. There is a transformation matrix associated with a frame, which transforms geometry defined in the "world" coordinate system to the local coordinate system.

| Argument | Type | Description |
|---|---|---|
| origin1 | Point | Origin of the frame |
| xloc | Point | Vector from origin1 to this point defines positive X direction |
| yloc | Point | Vector from origin1 to this point defines positive Y direction |
