Which file format for drawings is the most used and recommended for the industry?

Based on our 20+ years’ experience in the Foodservice, we strongly recommend the following:

• DWG files in AutoCAD 2004 version: this will permit final users with old planning software to open files without any problem of backward compatibility in the future.
• RFA files in Revit 2016 version: this will permit final users with old planning software to open files without any problem of backward compatibility in the future.
