When you open or save a CAD model using Pro/ENGINEER or SolidWorks, you may notice that the CAD software is able to open and save the model into many different formats. It is important for a CAD user and a designer to know these file formats, where they come from, and their use in solid modelling and product design. In this question, you are asked to create a list of only 3 file formats that are supported by Pro/ENGINEER and SolidWorks and report the following:

• File suffix and the name of the file format.
• Source of the file format. For neutral format, please report the nature of the format, its use in data exchange, and pros and cons.
