Hello,
I needed to create some flanged pipe spool pieces for polypropylene lined pipe. These spools won't require gaskets between each other but they do require gaskets at the valve faces. So I created a new joint type using the "To Not Include Gasket as a Joint for Flanged Components in OpenPlant Modeler" Wiki help. I performed the steps for "Case 2" and managed to place both the gasket joint (with gasket and bolt) and the no-gasket joint (bolts only) just fine.
However, I find that Connectivity Checker lists them both as Invalid Joints and I can't create any isometrics of the pipe.
Do you have any suggestions what could be causing this? Could it be something to do with using SPOOL_PIECES ?
