DRAW Reference Manual
Annotate Structural Elements in DRAW : P-line Attributes : P-line Design Element
The name of the Design element to which the p-line applies is stored in the DDNM attribute of the annotation element. When a p-line is in use, the p-point attributes (NPPT or PPDI) are normally unset (value -1). The exception to this is where p-line is used for angle. Refer to P-line Angle for further information.
