Design and print in 3D
Modellers for parts, buildings and rooms, from sketch-driven CAD to scripted solids.
FreeCAD
A parametric 3D modeller for real objects: design by sketching constrained 2D shapes, then change the parameters later.
OpenSCAD
A 3D modeller you write rather than draw: a script describes the object, and the program compiles it into a solid.
Blender
The free 3D creation suite: modelling, sculpting, rigging, animation, simulation, rendering, compositing and video editing.
Sweet Home 3D
Interior design software for drawing a floor plan, arranging furniture on it, and walking through the result in 3D.
