PLANT EQUIPMENT-PIPING-P&ID SOFTWARE

Hello,

I am new to the piping industry and have a software questions. I have recently learned the basics of the Bentley Auto Plant modeling software and now realize the numerous other software that is available for plant equipment layout, piping and p&id work. I have to ask, is the Bentley Auto Plant software regarded as one of the industry standard software or is there another best choice of software to invest in?
