Hi I am doing some 3D modeling and getting pressure class error.If I create a tank in equipment block it is giving block 300lb flanges.I am using CS150 spec which has 150lb flanges in it's spec.If I try and route pipe I am getting error:Cannot find flange in CS150 spec Pressure Class 300Flanged connection failed due to properties mismatchIf I try and modify equipment it will not allow me change 300lb to 150lbfor flanges on equipment block.Anybody know a fix for this?
