ISOTYPE

Function:

Defines whether the isometric shows fabrication information, erection information, or both.

Description:

The ISOTYPE command specifies whether the information on the drawing is intended for:

• In-shop fabrication and on-site erection In-shop fabrication

• On-site erection

• In-shop fabrication of pipe spools

A combined fabrication-erection isometric is a fully dimensioned and annotated isometric drawing with a material list specifying all piping components, bolts etc. This is the default.

A fabrication-only isometric is similar to the combined format except that the following information is omitted:

• The coordinates of Plant locations

• Erection materials

• CONNected TO and CONTinued ON comments at pipeline ends

The erection-only isometric is similar to the combined format except that all fabrication materials, apart from loose flanges, are omitted from the materials list.

A spool isometric shows only fabrication information. Loose flanges are included on spools, with the note ‘tack weld only’, if they have a SHOP attribute set to TRUE.

Isodraft automatically allocates spool break points at flanges or flanged components, field welds and erection materials, that is, items with their SHOP flag set to FALSE.

All components, including Tube, must have their SHOP attributes set to TRUE if spool break points are to be correctly allocated. The default setting for tube is FALSE, which would cause lengths of implied tube to be omitted when Isodraft calculates spool dimensions.

A spool number, automatically allocated by Isodraft, is plotted after the pipeline reference in the title block of each drawing. For example, 100-A-8 SPL[1].

Spool (erection in MATC) produces a Spool isometric, which includes erection material in the Material Control file.

Sheets with Blank Drawing Areas. Any type of the isometric can be produced with the actual drawing area left blank. That is, only the material list is plotted.

If ISOTYPE NONE is specified, no plot is produced. The user must specify output to text files, such as a material list, to get output.
