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.

If p-line data for an annotation element is replaced by a direct reference to a Design element or p-point, then the p-line attributes (PKEY and PKDI) are set back to the default values.
