Hi Jukka, For placement of auto flange, below are the two way you can do with flanges. A. Using AutoFlange table: - Enabling this option will place the valve without counter Flanges if there is no entry in it. However if you select and enter the size in AutoFlange table option using specification generator, it will deliver the spec grid with the selected flange to choose to pick the flange. See image below for your reference please. Below are the details you could find it from help file menu. Also see image below for quick reference. B. With No AutoFlange function: Placement of WNRF on valve by default is being done by the Autofitting Rule set in ‘AutoFittingRules.xml’ files available in the default system folder - C:\ProgramData\Bentley\OpenPlantModeler V8i\WorkSpace\OPModeler\System. You can modify the first entry on WNRF and set the LJF entry first. See image with default and with the changed settings. After modification: You need to add the End prep to LJ flange like shown for WNRF. However on loose flanges with Hub thickness, it is being calculated 2XFLG_TH_M value present in spec. I will check the possibility and update you on this. This will only affecting the graphical representation. On Collar dia is equal to Pipe OD and weld are also coming correctly by following above method. If you provide some steps to reproduce then we could be able to assist you further. Thank you for the files and your valuable input on this.Please let us know if it helps. Regards, Rahul Kumar
