DWGFast is a lightweight software designed to help users quickly view, edit and print 2D and 3D CAD drawings. DWGFast comes with measurement tools that allow administrators to quickly measure the length and area of models in a drawing. Designers can switch between different versions of DWG files and export them to JPEG, BMP, PDF, or PNG formats. For most people, DWGFast is a good choice because it provides a very complete function without having to buy expensive AutoCAD software.
