hello all,    I use autocad 2015 MEP and mostly draw HVAC pipe.. Was wondering if there was a command to check all connections or (snaps) of the node of a pipe to the node of a fitting or a weld?? We do as much prefab as possible in the shop and generate spool sheets for everything we make in the shop.. Pretty sure there used to be a command for 2013 that checked to make sure everything that was supposed to be connected was but i didnt know if that was only for design line wich i never use to draw...   thanks for the help..
