CAD tools:

3D Crafter

a real-time 3D modeling and animation tool that incorporates an intuitive drag-and-drop approach to create 3D models. Complex models can be constructed from simple 3D primitives, or created using 3D Crafter's Shape Building Tools. Modeling tools are provided to deform, sculpt, and paint 3D shapes. review

Blender 3.5

free and open source 3D creation suite. It supports the entirety of the 3D pipeline-modeling, rigging, animation, simulation, rendering, compositing and motion tracking, even video editing and game creation. review

BRL-Cad

a powerful open source cross-platform solid modeling system that includes interactive geometry editing, high-performance ray-tracing for rendering and geometric analysis, a system performance analysis benchmark suite, geometry libraries for application developers, and more than 30 years of active development. review

Cadstd lite 3.6.7

Simple and easy to use 2D computer aided design (CAD) program. 1 review

FreeCAD

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. review

gCAD3D 2.50.00

3D modelling tool with integrated 3D-OpenGL viewer. Supports import and export from.to Step, Iges, VRML, DXF, SVG ... review

K3D

3D modeling and animation software. It combines flexible plugins with a visualization pipeline architecture, making K-3D a versatile and powerful tool for artists. review

LeoCAD 0.83.2

CAD program that uses bricks similar to those found in many toys (like LEGO). Currently it has a library of more than 1000 different pieces. review

LibreCad

a feature-packed and mature 2D-CAD application. review

NanoCAD 5.0

a professional grade CAD design tool. It has a familiar interface, powerful drafting and design tools, native DWG compatibility, and an open API. review

Openscad 2021.01

free to use software for creating solid 3D models. Not an interactive modeller. Instead it is something like a 3D-compiler that reads in a script file that describes the object and renders the 3D model from this script file. 2 reviews

QCAD 3.28

open-source 2D CAD system. The developers main goals are to build a stable, fast and easy to use CAD for everyone. review

Solvespace 3.1

opensource parametric 2D/3D CAD software for sketching, solid modeling, mechanical parts prototyping and assembly creating. review
