The following six ATexts are used in DIRECTION records in the pipeline input data file when indicating compound directions for certain components in skewed Pipelines. Also used when ISOGEN is generating ORIENTATION and CONNECTION DIRECTION messages on flat spools.

*** REFERENCE FLAT ***

Used to identify which eccentric reducer flat direction is used as a reference for a given flange rotation.

-488

*** REFERENCE SPINDLE ***

Used to identify which spindle is used as a reference for a given flange rotation.

-489

*** REFERENCE SUPPORT ***

Used to identify which support is used as a reference for a given flange rotation.

-490

*** REFERENCE BRANCH ***

Used to identify which branch is used as a reference for a given flange rotation.

-491

*** REFERENCE WINDOW ***

Used to identify which window is used as a reference for a given flange rotation.

FLAT DIRECTION

Used to point to 2D and 3D skew enclosure triangles at eccentric reducers to indicate a flat direction on flat spools.

-493

SPINDLE DIRECTION

Used to point to 2D and 3D skew enclosure triangles located at spindles on flat spools.

-494

SUPPORT DIRECTION

Used to point to 2D and 3D skew enclosure triangles located at supports on flat spools.

-495

BRANCH DIRECTION

Used to point to 2D and 3D skew enclosure triangles located at undeveloped set-on branches or single olets on flat spools.

-496

WINDOW DIRECTION

Used to point to 2D and 3D skew enclosure triangles located at sight glasses on flat spools.

-497

FLANGE ROTATION ?

Used to identify flange rotations on flat spools. (The calculated angle is edited in by the software at the position of the ? character).
