During the inital desing of the pipe loop everything went together fine. i was able to route from point A to Point B and drop fitting in where ever i needed them. now i need to make some changes, and i have deleted some of my rounts to create new ones and for some reason the fittings, mainly flanges do not want to mate to each other. They will drop in the line just fine, but when i go to put to flanges together, it will not snap to it like it was doing before. What did do wrong and is there a way to fix this??
Im using Routing in version 2012
