Set OS 75 = 201 to display round-ended enclosures for erection welds (A) and diamond-ended enclosures for fabrication welds (B).
The following illustration shows the resulting output on the isometric drawing:
-
Fabrication and erection welds use their own weld numbering sequence.
-
Weld number prefixes are not shown.
Set OS 75 = 1211 to display round-ended enclosures for erection welds and diamond-ended enclosures for fabrication welds, all with weld number prefixes. The relationship between the switch settings and the isometric output are as follows:
-
A - Display erection weld prefix.
-
B - Output round-ended enclosures for erection welds.
-
C - Display fabrication weld prefix.
-
D - Output diamond-ended enclosures for fabrication welds.
The following illustration shows the resulting output on the isometric drawing (SH refers to fabrication welds, while ER refers to erection welds):
-
OS 75 controls only the weld number prefix option; it does not define the prefix character(s).
-
In the Isogen and Spoolgen systems, the prefix characters are defined using the -130, -131, -132, and -133 records.
-
In the IDFGEN system, the prefix characters are defined using the following pipe header attributes:
-
WELD-PREFIX-GENERAL
-
WELD-PREFIX-ERECTION
-
WELD-PREFIX-FABRICATION
-
WELD-PREFIX-OFFSHORE
-
