About Design Rule Parameters
In Piping, Design Rule parameters are line stock parameters that check selected pipelines to ensure that the pipes stay within their limitations. If there are any violations, this is considered a Line Stock violation. The system compares the characteristics of a selected pipeline with the values of the Design Rule parameters. If there are any violations, the pipeline is highlighted, which gives you the opportunity to correct the pipeline parameters.
Spec-Driven Piping uses Design Rule parameters for both the Non Spec-Driven and the Spec-Driven Piping modes.
To Define Design Rule Parameters in Spec-Driven Piping Mode
1. Click Design Rules. The Define Design Rules dialog box opens.
2. Under By Segment, click and select a pipe segment. This allows you to assign design rule parameters to a pipe segment.
or
Under By Parameters, select a linestock. This allows you to assign Design Rule parameters to an entire line stock.
3. Click Edit. The Design Rule Parameters dialog box opens.
4. Change the Design Rule parameters and press ENTER. A highlighted dot at the bottom of the dialog box confirms the entry.
5. Click to apply the Design Rule parameters and close the Design Rule Parameters dialog box.
 
* All bend radius and bend angle boxes are unavailable. Spec-Driven Piping retrieves this bend data from the Specification Database Bend Master Catalog (MCAT) file.
To Define Design Rule Parameters in Non Spec-Driven Piping Mode
1. Click Setup > Line Stock and select Create.
2. Type the name for the line stock and click . TheLineStock dialog box opens.
3. Click the DesignRule tab.
4. Change the Design Rule parameters and press ENTER.
5. Click OK to apply the Resign Rule parameters and close the LineStock dialog box.
 
* All bend radius and bend angle boxes are unavailable. Piping retrieves this bend data from the Specification Database Bend Master Catalog (MCAT) file.
