Preferences in 3D modelling software seem to be driven by brand names more than anything today. New 3D Modelling concepts are beginning to come on board such as Onshape, who offer online 3D modelling and file sharing, along with client login and reviewing without even having to download and install 3D modelling software programs. However these such sites are largely introduced where internet speeds are high and un-immpeded, and data files size is not a concern. In return they offer a quite simply and user friendly modelling program with simply tips along the way.

AutoCAD Inventor and Solidworks appear to hold major preferences amongst most modellers today, my personal preference for piping and plant development is certainly AutoCAD Plant 3D with its seemless integration and functionality.
