I prefer working as per below structure of execution:
1. Clients interested only for single Component/Part/Equipment Modeling : SOLIDWORKS+AUTOCAD (Both design files will be shared by default with no extra charges. Although,Clients can decide any one of these or complete service)
2. a) Clients interested for complete Process manufacturing Line and design of each equipment : DWSIM & COCO (Process Simulations) + (SOLIDWORKS** + AUTOCAD**) (** Clients can decide any one of these or complete service) To be charges extra.
Bid charges are per hour basis.
