ISOTYPE

Function:

Defines whether the isometric will show 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 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 only shows fabrication information. Loose flanges will be 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, will be plotted after the pipeline reference in the title block of each drawing. For example,

• 100-A-8 SPL[1].

A separate isometric drawing will be produced for each pipe spool.

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 will be plotted.

If ISOTYPE NONE is specified, no plot will be produced. You must specify output to text files, such as a material list, to get any output at all.
