WELDNUMBERS

Function:

Numbering the welds on an isometric.

Description:

The SPOOL module allows the user to set weld numbers automatically, and store these numbers in the Design database. If this feature is used it applies to an individual pipe, individual branch or to a spool drawing as defined in the SPOOL module.

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.

If the weld numbering feature 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. In addition, you can indicate that weld numbering is newly numbered for every single sheet, so on sheet 1, Weld 1, 2, 3... then on sheet 2 from same PIPE, Weld 1,2, 3... The default is that all WELD numbers are sequenced through all ISO sheets from the same PIPE.

Whether the user generates weld numbers in Model, SPOOL or in Isodraft, the size of the weld number characters can be specified using the CHARHeight setting. A table of the weld numbers can also be output onto the drawing sheet. The type of weld to be numbered can be fabrication only, erection only, or both. Weld numbering can be switched off completely, which is the default.

Additional welds can be shown on the isometric either in individual balloons or, if there are more than a specified number of them, as an arrowed message in a single ellipse (with the numbers separated by slashes).

Note:
If the SPOOL module is used 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 CHARH 2 GENERATED ACROSS

All generated weld numbers are sequenced through all ISO sheets for the same PIPE.

WELDN CHARH 2 GENERATED PER

Generated weld numbering is newly numbered for every single sheet.

WELDN FAB FROMDB

Outputs fabrication weld numbers from the Design database.

WELDN CHARH 2 FROMDB AWELDS BALLO 6

Output includes numbers for additional 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.
