About Orientation Data Table

This section describes the Pipe Spool orientation data tables.

If the spool contains joints (welds and glued connections), the orientation data table is generated in the drawing.

For example, an orientation data table is as shown below:

Orientation Table



PTS The point/node number in the spool.


JOIN The position number of the element to be oriented.


TO The position number of the 2nd element the connection.


ROLL The clockwise rotation angle to be applied to the element in the JOIN column after aligning it with the element in the WITH column. Looking from the element in the JOIN column in direction of the element in the WITH column.


WITH The reference element for the rotation angle. If the WITH column is blank, it means no reference element is available or the element to join has no significant standard orientation.

The spool corresponding to the above figure is as shown below:



Look from JOIN to WITH.


First align the parts (standardized orientation vectors).


Roll (rotate clockwise).


Look from JOIN to TO.

TO itself is a reference. (No third reference element needed.)
