PCF Generation Symbols Mapping

Overview

If you add a new piping symbol, you must include the new piping symbol in this mapping table.

In Data Setup, this mapping table should be assigned to:

The PCF Generation Symbols Mapping item in the resource table of Piping/Tubing Design Resources.

Rule Customization

Part of a typical PCF Generation Symbols Mapping table is shown below.


Piping-Symbol(AttributeName)	Iso-Symbol	Iso-Component	Comments	EndStyle
USER-DEFINED	BE	ANGLE_BEND	OK	PLAIN END
USER-DEFINED	L@	ANGLE_BEND	OK	PLAIN END
MITRE_BEND	MI	ANGLE_BEND	OK	THREADED MALE
USER-DEFINED	PB	ANGLE_BEND	OK	RAISED FACE
USER-DEFINED	PB+D	ANGLE_BEND	OK	RAISED FACE
PIPE_BEND	PBBW	ANGLE_BEND	OK	BUTT WELD
USER-DEFINED	BU	RETURN_BEND	NOT SUPPORTED	BUTT WELD
USER-DEFINED	BU+D	RETURN_BEND	NOT SUPPORTED	BUTT WELD

There are four columns in the table:


Column	Value	Description
Piping-Symbol(AttributeName)	The CATIA symbol	By default, the piping symbol is read on the V_SubPartType. If the attribute name exists, it must be valid and its value will be the piping symbol value.
Iso-Symbol	The equivalent Alias symbol	Refer to Alias documentation to determine the equivalent symbol value.
Iso-Component	The Alias component identifier	This is similar to a CATIA part type (valve, tee, etc.).
Comments	Any value	Comments
EndStyle	End style value	Attribute value from piping component.

Filtering Rules

If multiple rows with a similar Piping-Symbol exist, then the system decides a SKEY value based on filtering criteria using the Piping-Symbol and EndStyle columns.

The following tables show how the filtering works in different cases.

Case 1: If only 2 digit SKEY exist for the flange subtype and the End Style is BUTT WELD:


Part subtype	Symbol	New EndStyle	Action
FLANGE	FL		The first priority is given to 4 digit symbols (SKEY + New EndStyle). As there are no 4 digit symbols, then the second priority is given to 2 digit SKEY with a blank New EndStyle column and the first found entry is taken into account.
FLANGE	FU


Part subtype	Symbol	New EndStyle	Action
FLANGE	FL		For 2 digit SKEY, the New EndStyle column must be blank, otherwise an error occurs.
FLANGE	FU	BUTT WELD

Case 2: If only 3 or 4 digit SKEY exist for the flange subtype and the End Style is BUTT WELD:


Part subtype	Symbol	New EndStyle	Action
FLANGE	FLSO	SOCKET WELD
FLANGE	FLTO	THREADED MALE
FLANGE	FLBW	BUTT WELD	First found entry matching the part subtype and the end style is taken into account.
FLANGE	FUSO	WELD


Part subtype	Symbol	New EndStyle	Action
FLANGE	FLSO	SOCKET WELD
FLANGE	FLTO	THREADED MALE
FLANGE	FLBW		As no matching entry has been found, it takes into account the values of blank New EndStyle column.
FLANGE	FUSO	WELD


Part subtype	Symbol	Action
FLANGE	FLSO	As no end style value exists in the EndStyle column for all matching part subtypes, it applies the default behavior and takes into account the first found entry.
FLANGE	FLTO
FLANGE	FLBW
FLANGE	FUSO


Part subtype	Symbol	New EndStyle	Action
FLANGE	FLSO	SOCKET WELD	As no matching entry of part subtype and end style combination has been found, the systems searches for a blank EndStyle column value. As all the SKEYS are 4 digits SKEYS with an end style value in the column,
FLANGE	FLTO	THREADED MALE
FLANGE	FLPE	PLAIN END
FLANGE	FUSO	WELD

Case 3: If 2 or 3 (**)/4 SKEYS present for the flange subtype and the End Style is BUTT WELD:


Part subtype	Symbol	New EndStyle	Action
FLANGE	FL
FLANGE	FLTO	THREADED MALE
FLANGE	FLBW	BUTT WELD	The first priority is given to 4 digit SKEY + New EndStyle matching entry.
FLANGE	FUSO	WELD


Part subtype	Symbol	New EndStyle	Action
FLANGE	FL		The first priority is given to 4 digit SKEY + New EndStyle matching entry. As there is no 4 digit SKEY matching entry, then the second priority is given to 2 digit SKEY with a blank New EndStyle column and the first found entry is taken into account.
FLANGE	FLTO	THREADED MALE
FLANGE	FLPE	PLAIN END
FLANGE	FUSO	WELD


Part subtype	Symbol	New EndStyle	Action
FLANGE	FL	SOCKET WELD	The first proirity is given to 4 digit SKEY + New EndStyle matching entry. As there is no 4 digit SKEY matching entry, the second priority is given to 2 digit SKEY with a blank EndStyle column but no bank value in the New EndStyle column has been found and then an error occurs.
FLANGE	FLTO	THREADED MALE
FLANGE	FLPE	PLAIN END
FLANGE	FUSO	WELD


Part subtype	Symbol	New EndStyle	Action
FLANGE	FL	SOCKET WELD
FLANGE	FLTO	THREADED MALE
FLANGE	FLPE	PLAIN END
FLANGE	FUSO		The first proirity is given to 4 digit SKEY + New EndStyle matching entry. As there is no 4 digit SKEY matching entry, the second priority is given to 2 digit SKEY with a blank EndStyle column. No matching entry with 2 digit SKEY and a blank EndStyle value has been found but there is a 4 digit SKEY with blank end style value. Then this value is taken into account.


Part subtype	Symbol	New EndStyle	Action
FLANGE	FL		The first proirity is given to 4 digit SKEY + New EndStyle matching entry. As there is no 4 digit SKEY matching entry, the second priority is given to 2 digit SKEY with a blank EndStyle column. A blank End Style value has been found for a 2 digit SKEY and a 4 digit SKEY, therefore the priority is given to the 2 digit SKEY.
FLANGE	FLTO	THREADED MALE
FLANGE	FLPE	PLAIN END
FLANGE	FUSO


Part subtype	Symbol	Action
FLANGE	FL	Default behavior: the first entry is taken into account.
FLANGE	FLTO
FLANGE	FLBW
FLANGE	FUSO


Part subtype	Symbol	New EndStyle	Action
FLANGE	FL
FLANGE	FLTO	THREADED MALE
FLANGE	FLBW	BUTT WELD	The first priority is 4 digit SKEY with a matching end style. As two entries have been found, the first matching entry is taken into account.
FLANGE	FUSO	BUTT WELD
