Free CAD Software

Free CAD Software, DOWNLOAD NOW!

Free CAD software is a general purpose feature-based, parametric 3D modeler for CAD, MCAD, CAx, CAE and PLM, aimed directly at mechanical engineering and product design but also fits a wider range of uses in engineering, such as architecture or other engineering specialties. It is extremely modular, allowing for very advanced extension and customization. Free CAD software is based on OpenCasCade, a powerful geometry kernel, features an Open Inventor-compliant 3D scene representation model provided by the Coin 3D library, and a broad Python API. The interface is built with Qt. Free CAD software runs exactly the same way on Windows, Mac OSX and Linux platforms.(License included in download)

Why us?

Open CASCADE Technology

A complete Open CASCADE Technology-based geometry kernel allowing complex 3D operations on complex shape types, with native support for concepts like brep, nurbs curves and surfaces, a wide range of geometric entities, boolean operations and fillets, and built-in support of STEP and IGES formats.

Parametric Model

All objects are natively parametric, which means their shape can be based on properties or even depend on other objects, all changes being recalculated on demand, and recorded by the undo/redo stack. New object types can be added easily, that can even be fully programmed in Python.

Modular Architecture

A modular architecture that allow plugins (modules) to add functionality to the core application. Those extensions can be as complex as whole new applications programmed in C++ or as simple as Python scripts or self-recorded macros. You have complete access from the Python built-in interpreter, macros or external scripts to almost any part of our software.

Import/Export

Import/export to standard formats such as STEP, IGES, OBJ, STL, DXF, SVG, STL, DAE, IFC or OFF, NASTRAN, VRML. An Architecture module that allows BIM-like workflow, with IFC compatibility.

Robot simulation

A Robot simulation module that allows to study robot movements. The robot module already has an extended graphical interface allowing GUI-only workflow. Rendering module that can export 3D objects for rendering with external renderers.

Drawing Sheets

A Drawing sheets module that permit to put 2D views of your 3D models on a sheet. This modules then produces ready-to-export SVG or PDF sheets. The module is still sparse but already features a powerful Python functionality.

Our Software in Action

Our Software is everything you need to create presentation-ready floorplans, models, illustrations, and more. Setup wizards, snaps and alignment aids help you quickly layout designs. Access hundreds of tools to draw, modify, dimension and annotate designs, including specific tools for architectural and mechanical design. It's free, no worry about license costs or annual fees. No language barriers. It's available in a large number of languages, with more being added continually. All the powerful features you demand from a 2D/3D CAD application.
