Sketchy FFD (Free-Form Deformation) is a Ruby script plugin developed by C. B. Atkinson (often credited to the SketchUp community user "TIG"). It allows users to create a 3D grid of control points (a lattice) around a group or component, then move those points to smoothly deform the geometry inside.
Unlike native SketchUp tools (Move, Rotate, Scale), which work on rigid transformations, FFD works like a virtual cage. Pull one handle, and the geometry stretches organically toward it. sketchy ffd sketchup plugin
The primary advantage of SketchyFFD is its preservation of the "SketchUp feel." Unlike importing external scripts or switching to software like Blender or Rhino, SketchyFFD allows the designer to stay within the SketchUp interface. It democratizes organic modeling, allowing users who are not experts in NURBS (Non-Uniform Rational B-Splines) to create complex curvilinear forms.
