FreeCAD

FreeCAD is a general purpose parametric 3D CAD modeler. The development is completely Open Source (LGPL License). FreeCAD is aimed directly at mechanical engineering and product design but also fits in a wider range of uses around engineering, such as architecture or other engineering specialties. FreeCAD features tools similar to Catia, SolidWorks or Solid Edge, and therefore also falls into the category of MCAD, PLM, CAx and CAE.

Features:

• 3D modelling
• Parametric Modeling
• Computer-aided manufacturing (CAM)
• DWG support
• FEM
• Procedural modeling
• Windows XP Compatibility
• 3d Drawing
• Bim
• Drawing 2D

LibreCAD

LibreCAD (originally QCad then CADuntu) is an open source 2D CAD application for Windows, Apple and Linux. It is based on Qt, which is a leading cross-platform application and UI development framework. LibreCAD can read DWG files (and others) as of the latest Nightly build. It writes DXF files, but can also export SVG, JPG, PNG, PDF and other files.

Features:

• Bim
• Construction layers
• Drawing
• Portable

DraftSight

DraftSight is a professional-grade, open 2D CAD product for users who want a better way to read, write and share DWG files. DraftSight is easy to use and is available for professional CAD users, students and educators to download and activate for free.* Based on advanced architecture, DraftSight has a small footprint, should take less than a few minutes to download, and runs on multiple operating systems, including Windows XP®, Windows Vista® and Windows® 7.

Features:

• Drawing 2D
• 3d sketching

OpenSCAD

OpenSCAD is a software for creating solid 3D CAD objects. It is free software and available for Linux/UNIX, MS Windows and MacOS. Unlike most free software for creating 3D models (such as the famous application Blender) it does not focus on the artistic aspects of 3D modelling but instead on the CAD aspects.

nanoCAD

nanoCAD is a pro-grade 2D CAD system with native DWG support and full customizability. It is totally free, for business, professional, or personal purposes. It is fast, lightweight, capable, and , unlike most free CAD programs, completely uncrippled. nanoCAD includes: 1. Classic CAD interface. Any engineer could easily master nanoCAD since everything is in their right places: menu, button icons, panels, command line, and the commands theirselves are easily recognizable.

Features:

• 3D modelling
• Convert DWG to PDF
• DWG support
• Night mode/Dark Theme
• Convert PDF to DWG

QCAD

QCAD is an application for computer aided drafting in 2D. With QCAD you can create technical drawings such as plans for buildings, interiors, mechanical parts or schemas and diagrams. QCad uses the AutoCAD DXF file format internally and to save and import files. AutoCAD DWG support is available as a commercial plugin. QCAD is available in two versions: Community edition and Professional edition. QCAD Community Edition is free and open source.
