CGM
Files with cgm extension can be typically found as graphics files in Computer Graphics Metafile format. It is used for 2D vector graphics, raster graphics, and text, and is defined by ISO/IEC 8632. All graphical elements can be specified in a textual source file that can be compiled into a binary file or one of two text representations.
DWG
A dwg file extension is used for common CAD file format, originally used by AutoCAD. A DWG is a proprietary format and can only be created in AutoCAD. Other CAD programs can usually import it, but not create its proprietary form. It's because of this, that DWGs are often exported to DXF interchange format, so they can be seamlessly used in other CAD programs.
