I have a large piping system modeled. When I click the Start Run button, error checking shows two instances of Error 44E - Intersection Coordinate Mismatch exceeds the allowable. The nodes in question are connected. I even used the close loop function to see if that would solve the problem. I checked for duplicate node numbers throughout the model and could not find any.

This started when I modified a working model to reflect changes in the piping. I deleted and remodeled a large section of the piping that included the nodes giving me this error, but this did not help.

Has anyone else had this problem? Any suggestions on what to try next?
