Examples

name of zone like ^/STRU

returns ZONE names beginning "/STRU"

site

returns all SITES

zone

returns all ZONEs

bore of pipe gt 100

returns PIPEs with bore > 100mm

bore gt 100 of pipe

returns PIPEs with bore > 100mm

bore gt 4" of pipe

returns PIPEs with bore > 4 inches

bore gt 100 and :pdmsarea like 15A of pipe

returns PIPEs with bore > 100mm

and :PDMSAREA contains 15A

bore gt 100 and :pdmsarea = 15A of pipe and name of site like ^/STRU

returns PIPEs with bore > 100mm

and :PDMSAREA equals 15A which are under a SITE whose name begins "/STRU"

name of pipe like 'PIPE'

syntax error if 'PIPE' is not quoted (would otherwise be an unexpected GTYPE)

name of pipe like /PIPE

/PIPE does not need to be quoted, it will not be confused with a GTYPE

name of pipe not like 'PIPE'

returns all pipes whose name does not contain 'PIPE'

!PIPE

removes from the resulting list, any name containing the text 'PIPE'

Note:
Name of pipe not like 'PIPE' and !PIPE are very different, the former ADDs to the resulting List, the latter only removes items from the List.

name of bblock like .* and name of blevel like ACC

returns all blevels whose names contain "ACC" below all bblocks

Note:
For default Group Level element types (ZONE, PIPE, HVAC, BRAN, EQUI, SUBE, SUBS, FRMW, SBFR, SCTN, REST, HANG), the expression can use this type alone. Other types require sub-expressions which reference each prior level in order to locate the element. In the above example an expression such as "name of blevel like ACC" alone would not provide enough information and would generate an "Incomplete expression" error message.

Note: Any GTYPE used in an expression, unless it is one of the default Group Level element types, should be added to the GTYPE list on the Gtype/Tracking form (refer to Gtype/Tracking). Examples that would need to be added would include BBLOCK and BBLEVEL.

Note:
When using UDETs, do not add the actual type to the Gtype/Tracking form. Instead add the base type and use the base type in the expression. The actual type may be used as a sub-expression if required, for example, name of equi like '15A' and acttype like :pump.
