P1x1y1z1

P1x1y1z1 is a compact alphanumeric label used in spatial labeling systems to denote a specific coordinate triple associated with a base point designated as P1. It is not a standard across disciplines but appears in instructional material, datasets, and draft specifications to illustrate how coordinates can be encoded in a single identifier.

Notation and interpretation: The string combines a base reference P1 with axis components x1, y1, and z1. In practice, P1x1y1z1 is read as the coordinate triple (x1, y1, z1) measured in a given unit and expressed in the frame anchored at P1. The pattern can be extended to other bases such as P2x3y0z5 to indicate coordinates in a different reference frame.

Applications: In CAD, robotics, and geographic information systems, similar compact labels are used to tag points in diagrams and datasets to aid human readability and indexing. As an example, a design document might refer to P1x2y4z7 as the point where a component should be placed relative to base point P1.

Limitations and status: This notation is a descriptive device used for illustration in nonstandard contexts. It is not part of a formal, widely adopted naming convention, and its exact meaning depends on the surrounding documentation.
