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

Pointset and Geomset attributes can be defined in terms of a Dataset pseudo-attribute Real Property (RPROP). For example, the Pointset Bore (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 Real Property Flag (RUSE) attribute. If this attribute is set, the PROP attribute (or Default Property (DPRO), refer to 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.
