SLDDWG
An slddwg file extension is related to the SolidWorks, a 3D mechanical CAD modeling tool. An slddwg file contains 2D vector graphics data.
DWG
Files with dwg extension are used for the original CAD format originally introduced in Autodesk AutoCAD. The latest version of DWG format is usuaually proprietary and can only be created in AutoCAD. Other CAD programs can usually import it but not create its proprietary form. Because of this, DWGs are often exported to DXF interchange format so that they can be seamlessly used in other CAD programs.
