Background 

In OpenPlant Modeler placement of the wafer type components and valves should exhibit auto flange placement at its port. There might be several occasions where the users want to get different types of flanges to appear automatically. By default Weld Neck Flanges appear automatically. Refer to the image below where a valve has been placed. The Weld Neck Flange appears and connects automatically on both ends of the valve. 

          

The description below will assist the user to get different flange types (For Example: SLIP_ON Flange or a Lap Joint Flange) by changing the entries made in the AutoFittingRules.xml file.

Steps to Accomplish

1. Launch OpenPlant Project Administator CE.
   
   
   
   
2. Considering default Workspace and OpenPlantMetric project- Click on OpenPlant Modeler.
   Right Click on application OpenPlant Modeler and select Explore Here.
   
   
   
   
3. Clicking on Explore here… launches Modeler folder for that project itself and its content is displayed directly.
   Go to System in Modeler folder.

5. Search for flanges. See default entries below:
   
   
   
   
6. Add a similar entry in AutoFittingsRules.xml file for SLIP_ON_FLANGE along with End preparation details like shown for weld neck flange. One quicker approach is to copy existing entry and paste it above all. See below image.
   
   
   
   Note – Auto placement picks up the first entry made in above file
   
   
7. Save and Close File. 
   
   
8. Restart OpenPlant Modeler
   
   
   
   
9. Verify results by placing a valve on a pipeline.
