Alternative Texts - Isogen - Reference

Where applicable, each AText description includes its respective default value. If a default value is not specified, the AText is normally left blank.

For each AText, three options are available:

• <Default> uses the default AText value.

• <Suppress> suppresses the AText value.

• <Edit value> modifies the AText value with the user-specified entry.

Nominal Size

Denotes the pipe nominal size. By setting the AText to blank, the nominal size message is suppressed. Using the question mark (?) character determines the format used for outputting the nominal size message. The default value is ? NS.

Equipment Connection

Denotes CONNected TO where a pipeline branch end is connected to an equipment nozzle. The default value is CONN. TO.

Pipeline Connection

Denotes CONTinued ON at the point where a pipeline/branch end is continued onto another drawing. Used in conjunction with END-CONNECTION type record. Also used with AText -255 (Drawing Label) to create a CONT. ON DRG 2 type message when a pipeline is split across multiple drawings (isometric drawing area and material list overflow).For more information, see Alternative Texts in Drawing Area.Text. The default value is CONT. ON.

Continued From

Denotes CONTinued FROM. This message is plotted when a pipeline is split onto two or more drawings, such as CONT. FROM DRG 1.

The text DRG comes from AText -255 (Drawing Label).

Continuation Jacket

Denotes continuation of core pipe used on a jacket pipeline. The default value is CONT JACKET.

Continuation Core

Denotes continuation of jacket pipe on a core pipeline. The default value is CONT CORE.

Vent Callout

Plots an indicator that points to a vent position at any open-ended pipe. It is used in conjunction with an END-POSITION-VENT type record. The default value is VENT.

Pipe Spec Label

Plots an identification message that points to any place in the pipe where the piping specification changes. The name of the new specification is automatically indicted. The default value is SPEC.

Start Point Message

Plots a user-specified start point message on the isometric drawing. Use the special characters listed below to output information items as part of the message:

• ? - Output the system/pipeline reference (IDF record -25 or -6)

• ?? - Output the spool.

Drain Callout

Plots a message that points to a drain position on any open-ended pipe. Used in conjunction with an END-POSITION-DRAIN type record. The default value is DRAIN.

Open Callout

Produces a message at any open-ended pipe. Used in conjunction with an END-POSITION-OPEN type record.

Closed Callout

Produces a message at any open-ended pipe. Used in conjunction with an END-POSITION-OPEN type record. The default setting for this AText value is blank.

Null Callout

Produces a message at any miscellaneous pipe end. Used in conjunctions with an END-POSITION-NULL type record. The default setting for this AText value is blank.

Pipe Spec Change Label

Indicates a piping material specification change. The content of the PIPING-SPEC type record in the pipeline input data file is appended AText to form a composite message.

Insulation Spec Change Label

Indicates an insulation specification change. The content of the INSULATION-SPEC type record in the pipeline input data file is appended to the AText to form a composite message. The default value is INSUL.

Tracing Spec Change Label

Indicates a tracing specification change. The content of the TRACING-SPEC type record in the pipeline input data file is appended to the AText to form a composite message. The default value is TRACE.

Painting Spec Change Label

Indicates a PAINTING specification change. The content of the PAINTING-SPEC type record in the pipeline input data file is appended to the AText to form a composite message. The default value is PAINT.

Misc Spec 1 Change Label

Reserved for user-specified AText. The content of a MISC-SPEC1 type record in the pipeline input data file is appended to the AText to form a composite message.

Misc Spec 2 Change Label

Reserved for user-specified AText. The content of a MISC-SPEC2 type record in the pipeline input data file is appended to the AText to form a composite message.

Misc Spec 3 Change Label

Reserved for user-specified AText. The content of a MISC-SPEC3 type record in the pipeline input data file is appended to the AText to form a composite message.

Misc Spec 4 Change Label

Reserved for user-specified AText. The content of a MISC-SPEC4 type record in the pipeline input data file is appended to the AText to form a composite message.

Misc Spec 5 Change Label

Reserved for user-specified AText. The content of a MISC-SPEC5 type record in the pipeline input data file is appended to the AText to form a composite message.

Personnel Protection Label

Indicates personal protection type insulation. Indication symbols having the symbol key NPP. The default value is PP.

Reducing Elbow Label

Indicates a reducing elbow with symbol key ER** on fittings. The default value is REDUCING ELBOW.

Pipe Summary Ft

Indicates unit type feet in pipe centerline length region. The default value is FT.

Pipe Summary Ft-In

Indicates unit type feet-inches in pipe centerline length region. The default value is FT-INS.

Pipe Summary Insulation Heading

Controls the output of insulation length. The default value is blank.

Pipe Summary Tracing Heading

Controls the output trace length. The default value is blank.

ATexts -400 through -411 are used in the line summary area along the bottom of the isometric drawing and can have their values changed or made blank. If the AText value is changed, then its associated symbol is drawn. If set to blank, then the symbol is not drawn. In these ATexts, the inclusion of the dollar sign character ( $ ) creates a forced line feed that results in the text being plotted over two lines.

Traced Symbol Header

Plots text with the symbol for traced pipe in the Line Summary area. The default value is TRACED$PIPE.

Insulated Symbol Header

Plots text with the symbol for insulated pipe in the Line Summary area. The default value is LAGGED$PIPE.

Support Symbol Header

Plots text with the symbol for supports in the Line Summary area. The default value is PIPE$SUPPORT.

Compression Symbol Header

Plots text with the symbol for compression joints in the Line Summary area. The default value is COMPN$JOINT.

Screwed Symbol Header

Plots text with the symbol for screwed joints in the Line Summary area. The default value is SCREWED$JOINT.

Socket Symbol Header

Plots text with the symbol for socket welded joints in the Line Summary area. The default value is SOCKET$WELD.

Field Weld Symbol Header

Plots text with the symbol for field welds in the Line Summary area. The default value is FIELD$WELD.

Shop Weld Symbol Header

Plots text with the symbol for Fabrication or Shop welds in the Line Summary area. The default value is SHOP$WELD.

User Note 1

Represents any user-specified general information on the drawing frame. A typical example is PULLED BEND RADIUS IS 3X NOMINAL PIPE BORE. No default text.

User Note 2

Represents any user-specified general information on the drawing frame. A typical example is PULLED BEND RADIUS IS 3X NOMINAL PIPE BORE. No default text.

Spool Numbers Note

Signifies how spool numbers and material list part numbers are shown on the isometric drawing.

A preview of the default output is shown below:

Site Connection Symbol Header

Plots the text with the symbol for site connection in the Line Summary area of the isometric drawing.
