Best CAD Viewers for Windows

FreeCAD is an open-source parametric 3D modeler made primarily to design real-life objects of any size. Parametric modeling allows you to easily modify your design by going back into your model history and changing its parameters. FreeCAD allows you to sketch geometry constrained 2D shapes and use them as a base to build other objects. It contains many components to adjust dimensions or extract design details from 3D models to create high quality production ready drawings. FreeCAD is a multiplatfom (Windows, Mac and Linux), highly customizable and extensible software. It reads and writes to many open file formats such as STEP, IGES, STL, SVG, DXF, OBJ, IFC, DAE and many others, making it possible to seamlessly integrate it into your workflow. FreeCAD is designed to fit a wide range of uses including product design, mechanical engineering and architecture. Whether you are a hobbyist, a programmer, an experienced CAD user, a student or a teacher, you will feel right at home with FreeCAD.

ABViewer is universal software for PC for working with drawings. It enables you to view, edit, convert, measure and print DWG and other CAD files, as well as 3D models and raster images. You can work with a separate fragment of a drawing or, on the contrary, with a group of files. All this at an attractive price! ABViewer allows converting single files or a group of files. Batch conversion provides a wide range of export settings, for example, black-and-white mode, specifying the output file size, etc. The 3D section panel has controls for setting up visual display of 3D models and section planes. The panel is available in the 3D Viewer mode. The commands and options of the 3D Section panel enable to customize 3D model viewing. To display parts of a model, section and gizmo use the settings located at the top of the form. It is possible to create several planes at the same time.
