Dear Mr.Paul,
I feel 3d is good option . reason in 3d you can see
actaul look of plant & u can do checking for
interference, & Bill of material is 100 % accurate. I
know PDS & PDMS software...I like 2 work on PDMS
software. if you have any doubts on PDMS you can ask
me..you can extract drawing from PDMS model & give it
to AutoCAD format to client. so client can refer
AutoCad drawing.
Latest AutoPlant,CADMATIC & CADWORX is cheaper
software compare to PDS/PDMS , & thats is based on
AutoCAD
