SHOP Flag

Isodraft divides items in the Material List into Fabrication and Erection components. It does this by looking at the SHOP flag of the component: if the SHOP flag is set to TRUE, Isodraft lists the component as a Fabrication item; if it is set to FALSE, Isodraft lists the component as an Erection item.

Although you can set the SHOP flag specifically in the Design or SPOOLER modules by using the SHOP TRUE or SHOP FALSE command, it is more usual to set a SHOP selector in the Specification so that the flag is set automatically when the component is selected. The default, if the SHOP flag is unset, is SHOP FALSE.

Consider, for example, the following Specification.

Note: The default for SHOP is shown as =, meaning that the default setting is taken from the first SPCOM which satisfies all other selectors.

It is usual for all items except those such as Bolts, Gaskets, Valves, to be designated Fabrication items; that means, to have the SHOP flag set to TRUE.

If you need to make an exception to this convention, for example, to specify a loose flange for field fitting, you can override the SHOP flag during the component selection process thus:

NEW FLAN SEL WITH SHOP FALS

If you wish to use the same component with SHOP either TRUE or FALSE, you can have two lines in the Specification (that means, two SPCOMs) with the same basic Name but with distinguishing delimiters; for example, */FL100:T and */FL100:F. Isodraft ignores the delimiter and shows the same item code for each flange in the material list, that means, /FL100.
