Bend Rule

This section describes the Bend Rule tables and how you can customize them.

This page discusses:

Overview

This section provides a brief overview of the Bend Rule tables.

The Bend Rule table allows you to create links between Piping & Tubing Design and Knowledge Rules. Knowledge Rules can input only one resource table. The Bend Rule table is a summary of all design rules tables plus additional attributes that may have to be checked

In Data Setup, this table should be assigned to:

  • when using file-based tables, the Bend Rule item in the resource table of Piping/Tubing Design Resources.
  • when using Engineering Specification objects, a specification in the resource table of Piping/Tubing Specification Resources.

Table Description

This section describes the customization options of the Bend Rule tables.

File-Based Table

A typical Bend Rule file-based table is shown below.
