We have found 2 software records in our database eligible for .slddrw to .dwg file format conversion.
Except for Solidworks software, which is obvious choice for this conversion (it uses .slddrw files), you can also use other CAD programs that support import of SolidWorks' formats, for example AutoCAD (Not AutoCAD LT thought).
Some programs also require plugin to enable support for formats from other software platforms, so always explore the options of the programs you have access to.
SLDDRW
Files with slddrw extension can be found as CAD drawings from SolidWorks program by Dassault Systemes.
DWG
A dwg file extension is used for standard 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. Because of this, DWGs are often exported to DXF interchange format so that they can be seamlessly used in other CAD programs.
