Controls the following dimensioning requirements on the isometric drawing:
-
Dimension type, such as string/composite, support/comment, reference location and full string
-
Component dimensions to include or exclude gaskets
-
USA style dimensions, positioned on top of the dimension line
-
Additional allowances for pipe dimensions
-
Double dimensioning - imperial or metric
-
Dimensioning multi-way valves and instruments
-
Dimensioning of only pipe components, with fitting components remaining undimensioned
Switch Settings
The following settings are available for Option Switch 9:
SWITCH POSITION 1 - Various Controls
0 |
Plot ordinary string dimensions, support or message dimensions, and reference dimensions on the isometric drawing. This is the default setting. |
1 |
Plot only reference dimensions on the isometric drawing. All other dimensions are suppressed. |
2 |
Plot only support/message and reference location dimensions on the isometric drawing. |
3 |
Plot composited dimensions together with support/message dimensions and reference dimensions on the isometric drawing. |
4 |
Plot full string dimensions, support/message dimensions, and reference dimensions on the isometric drawing. All components are individually dimensioned. |
5 |
Plot ordinary string dimensions but do not dimension separately erection pipe fittings--such as bends, elbows, tees, and so forth--support/message dimensions, and reference dimensions on the isometric drawing. |
6 |
Plot composite dimensions but do not dimension separately erection pipe fittings--such as bends, elbows, tees, and so forth--support/message dimensions, and reference dimensions on the isometric drawing. |
7 |
Plot pipe dimensions, support/message dimensions and reference dimensions on the isometric drawing. Suppress dimensioning of all fittings. |
SWITCH POSITION 2 - Dimensioning of Gaskets
0 |
Exclude gaskets in component dimensions. |
1 |
Include gaskets in component dimensions. |
2 |
Dimension gaskets separately. |
SWITCH POSITION 3 - USA Style Dimensions
