Expanding bone anchor design.

grabcad

The bone anchor design is modeled after the Medshape Eclipse device; it employs reference geometry and in-context edits to create an animation. Initially, the design is compressed with an arced bottom and a Style Spline top. By editing the Style spline's vertices within the assembly, mates are created with reference objects that move away from their original positions. Subsequently, these reference objects are hidden, resulting in the illusion of a part expanding freely.
