Can anyone point me in the right direction for drawing pipes (straight only) and tubes (with bends) in Solidworks Standard version (no routing add-in)?  One suggestion I received was to use Weldments.  I worked through the tutorial but I am lost when trying to use it in an actual assembly.  I displayed the weldment toolbar but the Weldment icon is greyed out.  I am hoping I don't have to make sketches for each pipe or tubing I make.  I thought about making a part for a pipe and placing one in the drawing for each pipe.  Each pipe length would have to be defined by the mating constraints in the assembly.  Is this possible?

At this point I am doing conceptual work so I don't need to see every thread, fitting, etc; mainly just a pipe going from component A to component B.  Most are butt or socket weld anyway.  Perhaps I am jaded by my Sketchup days where I had a pipe after 3-4 mouse clicks with out much forethought.

Any help would be appreciated.  The assembly is included for reference.

Thanks,

Marty
