1) Solid Edge Viewer

Solid Edge is one of the most popular CAD software solutions on the market today thanks in large part due to its robust feature set which includes support for numerous file formats including AutoCAD's native .DWG and .DXF. With Solid Edge Viewer, users can interactively view 3D solid models as well as 2D drafting files from within a user-friendly interface that rivals traditional CAD applications.

Key Features:

Autodesk's own free viewer offers an impressive array of features including:

- Full support for AutoCAD (.DWG/.DXF), Inventor IPT and SolidWorks files

- Real-time 3D viewing & manipulation
