What is ProII mainly used for? Is there a difference from Pro E?

PROII is used for the calculation of chemical process flows and operational units, while PRO/E is used for equipment calculations; the two are not at all the same thing

Reply to 2# wss20011: Oh, then what can Pro/E calculate for devices? Are they some parameters of the main equipment?

Reply to 2# wss20011: Which one is better, ProII or Aspen?

PROII is a process simulation software, while PRO/E is used for equipment calculation; the two are not at all the same thing

　 Pro/E (Pro/Engineer, a computer-aided design software) is a key product of Parametric Technology Corporation (PTC). It holds an important position in the current field of 3D modeling software, and has been recognized and promoted by the industry as the new standard in the field of mechanical CAD/CAE/CAM worldwide; it is one of the most successful CAD/CAM software solutions available today. 　　Pro/E was the first to introduce the concept of parametric design, and it used a single database to address issues related to variability. Additionally, it adopts a modular approach, allowing users to choose based on their own needs without having to install all modules. Pro/E’s feature-based approach enables the integration of the entire process from design to production, facilitating parallel engineering. It can be applied not only to workstations but also to stand-alone machines. 　　Pro/E uses a modular approach, allowing for separate tasks such as sketching, part creation, assembly design, sheet metal design, and machining, so that users can choose to use the functions that suit their needs.

Reply to 6# srici: So that means Pro E is mainly a software used for mechanical tasks

Pro E is a 3D mechanical design software; it’s similar to CAD, as both are drawing software.
