Switch Settings

The following settings are available for Option Switch 53:

SWITCH POSITION 1 - Weld Number Text Size and Weld Type to be Numbered

0

Use no weld numbers. This is the default option.

1

Use small size weld numbers, 1.5mm high.

2

Use medium size weld numbers, 1.8mm high.

3

Use large size weld numbers, 2.1mm high.

4

Number only fabrication type welds - small size.

5

Number only fabrication type welds - medium size.

6

Number only fabrication type welds - large size.

7

Number only erection type welds - small size.

8

Number only erection type welds - medium size.

9

Number only erection type welds - large size.

  • These size values are only valid when weld numbers are being plotted in the original circular style enclosures.

  • Switch Position 1 should be set to value 0, 1, 2 or 3, if Switch Position 4 is set to value 0 or 1.

SWITCH POSITION 2 - Weld Box / Operations Box Generation

0

Set no weld / operations box. Nothing is plotted or printed. This is the default option.

1

Plot weld box summary.

2

Plot or print operations box summary.

SWITCH POSITION 3 - Weld Number Sequence Control

0

Continue the weld number sequence on each new drawing. This is the default.

1

Begin weld numbers at start of each new drawing.

2

Match spool isometric weld numbers to full isometric weld numbers when using continuous weld numbers across drawings.

3

Match spool isometric weld numbers to full isometric weld numbers when using the weld number sequence commencing on each drawing.

4

Suppress the generation of weld numbers.

SWITCH POSITION 4 - Offshore Weld Number Control

0

Generate offshore weld numbers. This is the default.

1

Number offshore welds only.

2

Do not number offshore welds.

This switch position should be set to value 2 when Position 1 is set to value 4, 5, 6, 7, 8 or 9.

SWITCH POSITION 5 - Individual Weld Numbering Sequences

0

Use a single sequence for all welds.

1

Use an individual sequence for each weld category.

SWITCH POSITION 6 - Support Weld Sequences

0

Use the same sequence as that used for standard welds.

1

Use a single sequence for all support welds.

2

Use an individual sequence for each support weld category.

SWITCH POSITION 7 - Support Weld Numbering Sequences

0

Continue the support weld sequence on each new drawing.

1

Start support weld numbers at 1 on each new drawing.

SWITCH POSITION 8 - Alphabetic Weld Identifiers Generated

0

Use numeric weld identifiers.

1

Use alphabetic weld identifiers.

SWITCH POSITION 9 - Number of Characters in the Weld Identifier

0

Exclude leading characters before output of weld identifier.

Value

Use the minimum number of characters in a weld number, and adds leading zeros to attain Value set.
