I need to build a P&ID diagram for our process.  I am new to Solidworks coming from an AutoCAD 2D package.  Is there an easy way to build these pipe diagrams?  Our current versions does not have the pipe routing option yet.  It looks like it would be a fairly clean way to draw the piping.  In our current setup, it looks like the only way to do this is to create an assembly of pipe sections and equipment.  Am I seeing this wrong?
