PDMS PSEUDO ATTRIBUTES

PSEUDO ATTRIBUTES

In order to get specific information directly from the database, a number of keyword or pseudo
attributes have been introduced. Pseudo attributes are not attributes as such, but they have
the ability to extract data when queried. For Example

• ELBO 1 --->>>> Go to elbo 1 of the branch

• Q PARAM --->>>> Query the parameters of the catref of the spref

• Q DTXR --->>>> Query the rtext of the detref of the spref_ can also use dtxs or dtxt

• Q MTXX --->>>> Query the xtext of the matref of the spref _ can also use mtxy or mtxz

• Q PSATTS --->>>> Query the list of pseudo attributes available for the CE.

A few useful pseudo attributes appear below:

General Queries

• Q LIST --->>>> Query what you can create below the current element

• Q OLIST --->>>>Query the type of elements which can own CE

• Q ORDER --->>>>Query the list position

• Q PROP DESC --->>>> Query the data element with the dkey equal to DESC in the component's dataset (Steelwork and Piping elements)

• Q PRLS --->>>> Query the list of properties in the component's dataset

• Q PURP XXX --->>>> Query the purpose attribute of the property XXX

Piping Attributes

• Q CHOICE --->>>> Query the answers of the selectors of the spref

• Q CHOICE STYP --->>>> Query the styp used to select the component

• Q PL BOP --->>>> Query the bottom of pipe elevation of the leave point

• Q PA INSU --->>>> Query the insulation thickness at the arrive point

• Q PGRAD 1 --->>>> Query the slope at ppoint 1

• Q ITLE --->>>> Query the length of implied tube (must navigate first by using 'IL TUBE' at a component)

• Q LBOR --->>>> Query the leave bore

• Q ABOR --->>>> Query the arrive bore

• Q APOS --->>>> Query the arrive position

• Q LPOS --->>>> Query the leave position

At Branch Level

• Q TULEN --->>>> Query the length of tube in a branch

• Q CLLEN --->>>> Query the centerline length through all components

Steelwork

• Q ODESP --->>>> Query the design params of the joint owner

• Q ADESP --->>>> Query the design params of the joint attached beam

• Q DRPS --->>>> Query the derived position of the beam start

• Q NWEI -->>>> Query the net weight (considering joint cut outs)

• Q GWEI --->>>> Query the gross weight (beam before cutting)

• Q NCOF --->>>> Query the net centre of gravity for the beam

• Q NSRF --->>>> Query the net surface area

• Q MIDP --->>>> Query the mid point

• Q POS PPLINE TOS START WRT /* --->>>> Query TOS of current element (SCTN)

• Q PPLINE TOS DIR --->>>> Query the direction of the TOS pline on a SCTN
