I have a vacuum tube assembly I am putting together and I am at my wits end, as all the mates are either concentric, distance between 2 faces or coincident at to faces and planes, be it parallel between parts or planes of identical parts or angles between planes. I get so far and all of a sudden every mate errors out and get a yellow mark or red, and I can't seem to find a single reason for it. has any experienced this and is there a work around as I am spending more time chasing mate errors than making my assembly.
I have 5 types of parts straight pipe, a Y-fitting, a 45 degree elbow, a 90 degree elbow, and a clamp all are modeled on a plane and all have a 2" min straight section, so again how can I keep getting errors. I'd post a picture but my assembly is in the lock up mode now and want to give it a chance to recover.
