Real Properties of P-points, P-Lines and Geomsets

Pointset and Geomset attributes can be defined in terms of a Dataset pseudo-attribute RPROP (Real Property). For example, the PBORE of a P-point can be defined by the expression:

PBORE ( PARAM[1] + 20 )

If the dataset associated with the component contains a DATA element with the Datakey DBOR, and DBOR has its PPRO attribute set to the expression ( PARAM[1] + 20 ), PBORE can be defined as:

PBORE ( RPROP DBOR )

Pointset and Geomsets with attributes defined in terms of RPROPs will have their RFLG flag set to 1. Only elements with RFLG set to 1 need to be pre-evaluated when the item is added to a model.

DATA elements have an attribute RUSE. If this attribute is set, the PROP attribute (or default Property DPRO, see Controlling the Detailed Checking Procedure) cannot be set to a text expression or to an expression containing the OF notation. RUSE is set (=1) and unset (=0) using the commands:

SETRuse

UNSETRuse

DATA elements with PROP attributes property which can be used as RPROPs should have their RUSE flags set. Only elements with RUSE set to 1 need to be pre-evaluated.
