OK so I just finished my first Revit project. Sort of - we pretty much used it just for drafting purposes. Something that drove me nuts - for the life of me I couldnt get two pipes to connect to each other. I tried editing the system and adding pipes to the system. I know they were at the same elevation and aligned. I tried drawing from the end of one pipe to the end of another pipe and they usually wouldnt connect. is there a trick to this? I ended up with probably 60 different systems in a building that had about 10 systems because it kept putting my pipes on different systems and not allowing me to connect them together. Thanks
