Argon™ is a CAD and 3D precision modeling software for Mac and Windows. It offers wireframe, solid and surface history-free modeling with precision drawings, photo-realistic renderings and animation.




FreeCAD is described as 'A versatile open-source 3D CAD modeler with modular architecture, suitable for engineering applications across multiple platforms, supporting Python scripting' and is a leading CAD software in the photos & graphics category. There are more than 100 alternatives to FreeCAD for a variety of platforms, including Windows, Mac, Linux, Web-based and SaaS apps. The best FreeCAD alternative is SketchUp. It's not free, so if you're looking for a free alternative, you could try OpenSCAD or Onshape. Other great apps like FreeCAD are Autodesk AutoCAD, SOLIDWORKS, SolveSpace and FluidCAD.

Sverchok is a parametric tool for architects and designers. You can use it to program objects' shapes without knowing any programming languages.

HyperFun is a simple specialized high-level programming language. It is intended for modeling geometric objects and their internal volumetric properties (color, material density and others). A model can include objects of mixed dimensions (1D, 2D, 3D, 4D and even kD)) defined by...

CaDoodle is a local drag-and-drop CAD application for Linux (Arm,x86), WIndows (X86), and Mac (Arm,x86) and ChromeOS. Users models are stored locally, and the application runs entirely locally. CaDoodle has a drag and drop interface that is cross-trainable with TinkerCAD.



The software’s particular strength lies in the three-dimensional general arrangement and reinforcement design. With this, the building construction is carried out in advance, so that discrepancies and conflicts are already visible in the planning phase.
Graphite is an easy to use precision 2D/3D CAD software for product design and development. Formerly known as Vellum, Graphite offers extremely powerful, precision wire-frame drafting with the elegant ease-of-use that makes it productive even when only used occasionally.





Formerly Vellum Solids, Xenon™ is an associative 3D modeling software for product design and development that's easy to use. It offers history-based wireframe, solid and surface modeling with precision drawings, renderings and animation.
