Material Tags

Some of the tags in m–file are originally sent from Plant Modeller via the geometry transfer file to Piping Isometrics & Spools, and Piping Isometrics & Spools just passes them into the m–file.

The general rule is that all attributes assigned to parts are sent to Piping Isometrics & Spools.

  • .FI – The length of a straight pipe piece that is required for a part of a bent pipe, including any extra length required by manufacturing. The information is only published for bent pipes, and only in contexts where these parts are treated as independent entities such as the Object properties dialog or an eBrowser model, but not for example in material lists since there a bent pipe is treated as one entity.

  • bid – Part ID string for the pipe material from which the bend is made.

  • bnt – Specifies the bending table (dimension table) and line number in the bending table. Format is 'dimtbl'-'line'. Lines are counted from 0. Not present for free bends.

  • bra – Bending radius of bends.

  • caw – Indicates how much of the pipe needs to be cut away after the pipe has been fabricated.

  • ext – Index to extra material in the transfer file. In m–files the presence of this tag specifies that the record represents extra material.

  • exl – Increments the cut length of pipe.

  • el1 and el2 – Extra lengths at ends of pipe managed via attributes. Pipe parts can have extra length assigned to the start and end. These values are stored via internal attributes '.Extra Length At Start' and '.Extra Length At End'. Tags that are used in isometric transfer files and in m–files are 'el1' and 'el2'.

    Start and end are as seen in pipe routing order. During pipe cuts and joins Plant Modeller tries to keep track of which extra length belongs to which end.

  • FBO – Flange bolt orientation. This contains the information necessary for computing rotation angles.

  • fii – Bending angle of a curved component (bend or flexible elbow).

  • len – The length of the pipe. Includes 'exl' , 'el1' and 'el2'.

  • mth – Manufacturing method, such as $B or $T.

  • pli – Name of pipeline. This tag is generated for each part if the isometric contains parts from more than one pipeline.

  • spn – Spool name.

Weld Label Tags

In automatic annotation, Piping Isometrics & Spools creates weld point labels if "Weld/joint labels" is enabled in the settings, as described in Other labels. The weld symbol is a chamfered rectangle or a circle (WeldLabel.asy). The default weld IDs are 1, 2, 3, … The user can manage weld labels via Label > Insert Special > Weld Point Labels. Weld point data is stored in the file Isoname.0.wld. When saving the picture, the program writes weld entries also to the m–file.

The format of the Isoname.0.wld file is as follows:

nam Isoname;nop NumberOfPoints;now NumberOfWelds;nnw NextNewWeldId;;

wld WeldId;typ WeldType;bra IfBranch;fpp 1.PartPnt;fob 1.ObjectId;

fpi 1.PartId;spp 2.PartPnt;sob 2.ObjectId;spi 2.PartId;;

  • wID – Weld id (1...).
  • wTY – Type (0,1 where 1 = field weld).
  • wBR – Is branch (0/1 where 1 = first part (wFP) is a branch part and second part (wSP) is the main run).

First part:

  • wFP – Part id (pid).
  • wFC – Connection code.
  • wFD – Dimensional description.
  • wFN – Nominal size.
  • wFW – Wall thickness.
  • wFM – Material.

Second part:

  • wSP – Part id (pid).
  • wSC – Connection code.
  • wSD – Dimensional description.
  • wSN – Nominal size.
  • wSW – Wall thickness.
  • wSM – Material.

Stub-in Branch Tags

When saving pictures, the program adds (PiMfile.mac) information about stub-in branches to the m–file.

Example row in m–file:

pid 20_95_DNV2_-5;mth $T;qty 1;pli 8512;rPI 20_95_DNV2_-7;

rDE SEAMLESS PIPE;rMC St.;rDD 139.7x4.5;rpl 8512;rNS 125;

rba 90.00;rbe 0;;

  • pid – Part ID of the branch.
  • mth – Method of the branch ($T).
  • qty – Quantity (always 1).
  • pli – Pipeline ID of the branch.
  • rPI – Part ID of the main run.
  • rDE – Description of the main run.
  • rMC – Material of the main run.
  • rDD – Dimensional description of the main run.
  • rpl – Pipeline ID of the main run.
  • rNS – Nominal size of the main run.
  • rba – Angle (in degrees) between the main run and the branch pipe.
  • rbe – Eccentricity (in millimeters) of the branch from the main run.
