3D Crafter
3D Craftera real-time 3D modeling and animation tool that incorporates an intuitive drag-and-drop approach to 3D modeling. 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. Comments 
Blender 2.82a updated
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. Comments 
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. Comments 
Cadstd lite 3.6.7
Simple and easy to use 2D computer aided design (CAD) program. Comments: 1
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. Comments 
gCAD3D 2.46.04 updated
3D modelling tool with integrated 3D-OpenGL viewer. Supports import and export from.to Step, Iges, VRML, DXF, SVG ... Comments 
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. Comments 
LeoCAD 0.83.2
LeoCADCAD program that uses bricks similar to those found in many toys (like LEGO). Currently it has a library of more than 1000 different pieces. Comments 
LibreCad
a feature-packed and mature 2D-CAD application. Comments 
NanoCAD 5.0
a professional grade CAD tool. It has a familiar interface, powerful drafting and design tools, native DWG compatibility, and an open API. Comments 
Openscad
free to use software for creating solid 3D CAD 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. Comments: 2
QCAD 3.24
open-source 2D CAD system. The developers main goals are to build a stable, fast and easy to use CAD for everyone. Comments
