The DWG or “Drawing” format is one of the most efficient and popular in handling computer-aided design or drafting (CAD), mostly in connection to software such as AutoCAD or IntelliCAD. If you work in architecture, construction engineering or design, this is probably the format you use most often. And though you probably appreciate DWG files because they allow you to store, edit and optimize 3D design data and metadata, you might have also encountered difficulties with handling them.
