4 FreeCAD – Alternative software for Autocad

FreeCAD 10 useful Free alternative to AutoCAD

FreeCAD is a common purpose parametric 3D modeler for CAD, MCAD, CAx, CAE, and PLM.

It mainly uses for mechanical engineering and product design but also fits a broader range of uses in engineering, similar to architecture or other engineering works.

It is 100% Open Source and intensely modular, giving a very advanced extension and customization.

FreeCAD relies on OpenCasCade, a robust geometry kernel that highlights an Open Inventor compliant 3D scene representation model proposed by the Coin 3D library and a broad Python API.

The interface develops with Qt Framework. FreeCAD runs the same method on Windows, Mac OS, and Linux platforms. – FreeCAD

5 LibreCAD – Free Autocad alternative

LibreCAD is a 2D CAD software written in C++11 using the Qt framework. It might probably read DXF and DWG files and can write DXF, PDF, and SVG files.

The user interface is extremely customizable and has dozens of translations.

LibreCAD is a community version of QCAD that uses the cross platform framework Qt, which means it works with most operating systems. – LibreCAD

6 Openscad – 3D alternative for AutoCAD

Openscad 10 useful Free alternative to AutoCAD

OpenSCAD is a free CAD software for creating solid 3D CAD models. Unlike most free software for creating 3D models, it doesn’t focus on the creative parts of 3D modeling but instead on the CAD aspects.

The software is not an interactive modeler. Instead, it is something like a 3D Compiler that uses a script file to build the object and renders the 3D model from that script file.

That gives you full control over the modeling process and lets you allow to change any step within the modeling process or make designs which might be defined by configurable parameters.

There are two different modeling methods offer by OpenSCAD. First, there may be constructive solid geometry, and second, there is an extrusion of 2D outlines.

You can use Autocad DXF files as a data exchange format for 2D Outlines. Along with 2D paths for extrusion, which have the potential to read design parameters from DXF files.

Apart from DXF files, OpenSCAD can also read and create 3D models within the STL and OFF file formats.
