The content of each isometric drawing is calculated using complex algorithms to display all of the required data in the available space. the algorithms are controlled by Standard iso options selected before plotting the drawing.
The drawings are not to scale but display to show the information in the best way. Pipes with no components attached to them, at the end of the spool drawing, may even be abbreviated with just the annotation showing the length.l
Each piping component in the Preview Isometric Drawing window is annotated and a symbol. The general format, annotations and dimensioning standard of the isometric drawing is governed by user in IsodraftI, refer to Using Isodraft for further information. The annotation data is also controlled by the selection made in the Spool module.
Piping component annotations in the Preview Isometric Drawing window are governed by ISODRAFT. An example of some can be seen below:
|
Annotation |
Key |
Remarks |
|---|---|---|
|
Dimension |
Value display in dimensioning line break, or directed to line by arrow. |
|
|
Spool Number |
Number in a double box with the spool prefix. |
Arrow points at the first component in the spool. |
|
Part Number |
Number in a rectangular box, along pipe or arrow pointing to component. |
Flanged components also show the Gasket (Gxx) and Bolt set (Bxx) numbers. |
|
Weld Number |
Number in a circle |
Key for different types of weld displays on the plot. |
|
Joint Number |
Number in a diamond, prefixed by letter showing type of joint. |
F = Flanged joint S = Screwed joint C = Compression joint |
Refer to Piping Components in Isodraft for a full description of all of the symbols used in the plots.
