Creating Pipe Component Information
The coordinate information of pipe segments and other components is converted to millimeters if the corresponding assembly uses metric units. If the corresponding assembly uses imperial units, the coordinate information of pipe segments and other components is converted to inches. Use the ISOGEN switches to display the units on the isometric drawing during the isometric drawing generation. The nominal size information is extracted from the Piping component.
The ISOGEN component identifier and the information extracted is shown in the next table.
PCF Identifier
Description
BRANCH1-POINT BRANCH2-POINT
Identifies branch points on various components. For example, a typical record using millimeter (mm) coordinates and an inch bore is as follows:
BRANCH1-POINT 125.0 25.0 0.0 6 BW
* 
The data string after the identifier BRANCH1-POINT includes coordinates, a nominal size, and an end type as expected by the PCF file format.
CENTRE-POINT
Identifies the center point on various components. For example, a typical record using millimeter (mm) coordinates and an inch bore is as follows:
CENTRE-POINT 125.0 0.0 0.0
* 
The data string after the identifier CENTRE-POINT includes coordinates.
END-POINT
Identifies end points on various components. For example, a record using millimeter (mm) coordinates and an inch bore is as follows:
END-POINT 150.0 25.0 0.0 6BW
* 
The data string after the identifier END-POINT includes coordinates, a nominal size, and an endtype as expected by PCF file format.
SKEY
Valid ISOGEN SKEY (Symbol Key). For example, a record identifying SKEY is as follows:
SKEY VGBW
ITEM-CODE
Unique identifier for each component. Piping component STOCKNO (stock number) is used as ITEM-CODE. The ITEM-CODE and the description are used to populate the bill of materials. For example, a record identifying ITEM-CODE is as follows:
ITEM-CODE GATVAA050
ANGLE
Angle value if the angle is other than 90 or 180 degrees for ELBOW, BEND, OLET, TEE, and ELBOW-TEED type components. Angle values are in hundredths of degrees. For example, a record identifying an ANGLE of 60 degrees is as follows:
ANGLE 6000
SPINDLE-DIRECTION
Direction of Spindle (Operator) on VALVE. Defines primary direction only. Valid directions values are NORTH, SOUTH, EAST, WEST, UP and DOWN. For example, a record identifying SPINDLE-DIRECTION is as follows:
SPINDLE-DIRECTION NORTH
FLAT-DIRECTION
Direction of Flat side of Eccentric Reducers (ERED). Defines primary direction only. Valid directions values are NORTH, SOUTH, EAST, WEST, UP and DOWN. For example, a record identifying FLAT-DIRECTION is as follows:
FLAT-DIRECTION NORTH
DIRECTION
Used to indicate VALVE Spindle direction and Eccentric Reducer Flat direction that is in primary plane. Value in a form Up 45 deg. North will be shown as a graphical output in primary direction. For example, a record identifying DIRECTION is as follows:
Up 45 deg. North
* 
PCF identifiers BRANCH1-POINT, BRANCH2-POINT, CENTRE-POINT are specific to components and are not applicable for pipe segments.
