FreeCAD 'xhtml' 3D exported (use 'D' and 'V' for debug)

3D Model Description:

FreeCAD X3D plus KiCAD exported 3D model in xhtml thanks to Werner :)

A complete Open CASCADE Technology-based geometry kernel allowing complex 3D operations on complex shape types, with native support for concepts like Boundary Representation (brep), Non-uniform rational basis spline (nurbs) curves and surfaces, a wide range of geometric entities, boolean operations and fillets, and built-in support of STEP and IGES formats A full parametric model. All FreeCAD objects are natively parametric, meaning their shape can be based on properties or even depend on other objects. All changes are recalculated on demand, and recorded by an undo/redo stack. New object types can be added easily, and can even be fully programmed in Python.
