WELDNUMBERS

Function:

Numbering the welds on an isometric.

Description:

Welds can be created in different ways depending on user preferences.

The Spool module allows the user to create pipe spools by choosing the extents of a spool from the Design model. The resulting SPLDRG elements store the spool configuration and all the welds to be used in Isodraft. SPLDRG’s are stored in a special (ISOD) database which is used by Isodraft to generate spool Iso’s.

If this feature is used it applies to an individual pipe, individual branch or to a spool drawing as defined in the Spool module.

Welds can also be created in the DESIGN database using actual weld elements inserted into the model where required. This can be done as individual welds or using the Weld Handling function in the Pipe Fabrication application.

If the weld modelling features of Model or Spool has not been used, Isodraft can produce weld numbers according to its own system defaults. However, these numbers are not maintained between revisions.

The WELDNUMBERS FROMDB command allows the user to access these numbers from the DESIGN database. When using this feature, if Isodraft finds any unnumbered welds it displays an error message and halts the drawing of the isometric.

Note: When creating a SPLDRG isometric to generate weld numbers, the user can output a weld table on the isometric to their own specifications using the POSITION command. For generated weld numbers, the table has a fixed position and content.

Examples:

WELDN CHARH 1.5 FAB

Outputs fabrication weld numbers with a character height of 1.5mm.

WELDN CHARH 1.8 EREC BOX

Outputs erection weld numbers with a character height of 1.8mm, and tabulates them in a box immediately above the title block.

WELDN CHARH 2.0 BOX

Outputs all weld numbers with a character height of 2.0mm in a table.

WELDN OFF

Suppresses the output of weld numbers.

WELDN FAB FROMDB

Outputs fabrication weld numbers from the DESIGN database.

WELDN CHARH 2 FROMDB AWELDS BALLO 6

Output includes numbers for attached fabrication welds. These will be shown in separate balloons if there are no more than 6, otherwise they will be shown together in an ellipse.
