free form biomorphic structures

rapid prototyping [2.5]

Rapid Prototyping requires a model that only contains closed 'solids' that is elements with a clear 'inside and 'outside'. For example eight square surfaces can form a solid cube. when the model is imported back to Rhino from the analysis package, it consists of a number of disjointed cubes that intersect one another. For successful rapid prototyping these surfaces need re-connecting. The easier ones to correct are the planar cross-sections (rings).

1. A construction plane is created.

2. The model is aligned with the plane.

3. The model with the original UV curves is now ready to be offset.

4. The original model is lofted and the rings are color coded for easy identification.

5. Each lofted surface is then extruded and capped.

6. The wireframe is then extracted from the model.

7. The longitudinal curves are then offset.

8. The longitudinal elements have been 'normalised' to the surface of the model.

9. The final continuous 'solid elements are now ready for prototyping.
