These are modules of PDMS:
design ,draft,specon,paragon,and admin.
Global is way to share projects over multiple locations in the world (hence teh name global)
Bolting is the way piping is connected. So not a module.
at first you must learn design module (to creating 3d model) so learn draft to create draft from model after to be enough expert learn other module
I disagree, if you are a structural designer then learn the structural module, if piping designer learn piping module, if mechanical designer learn equipment module and so on. All designers are recommended to learn Draft, leave specon, procon to the administrators. Remember pdms is to be used by designers not modellers! otherwise how do you know what you are designing??
