Ligno3D Designer is a simple CAD program that is fast, easy to learn and fun to use.  Initially aimed at wood- workers, but now used by many others, it specialises in the design of faceted 3D objects with few right angles — e.g., polyhedra, geodesic domes, compound roofs, weird houses, crystal models, gems, unusual furniture, sculptures and decorations.  It also does spiral stairs, tents, balloons, speaker enclosures, stealth aircraft, tanks, boats & coffins — almost any faceted object imaginable (see Gallery).  Download for Free to try it, then Buy an Activation File to use it in earnest.

Ligno3D Designer helps you build projects that would otherwise be far too difficult.  It solves the geometry problems associated with complex polyhedral objects, especially the solid angles needed to cut the edges of the faces.  The help system includes instructions for making such objects from panel material, using biscuit joints and PVA glue.  You can even do dovetail joints and frameworks.  Take a peek into the Workshop.

Ligno3D Designer is 'inverse CAD' without the steep learning curve.  You work directly in a 3D perspective environment with solid objects that are rapidly panned, rotated and zoomed.  Create, move, clone, subdivide and delete vertices and faces with consummate ease and absolute precision.  Boost your creative talents by deploying an arsenal of tools and symmetry elements.  See Screenshots, Features & Online Manual for more.

Having designed your project in 3D, click a button to view or print 'unwrapped' 2D plans of all faces.  The 2D plans show exact edge and diagonal dimensions, inter-edge and dihedral angles, and the IDs of all vertices and adjacent faces.  You can also exchange DXF, STL and BMP files with other programs.
