By digitizing an object using a software like 123D catch, it is now possible to model the object without having to take measurements. This concept of photogrammetry measures photographs to generate 3D models.

Location – Sant Antoni
Object – Water fountain
The water fountain was one of the few peculiar objects of this station.
Process – Photos with phone camera – 123D catch to process a model – saved to OBJ – imported to Rhino
Obj/mesh was locked in one layer. The entire model was traced over it, but using proportionate rectangles and polygons to generate a model. Offset, extrude, mirror, loft, planar curves, variable fillet were amongst the main commands used.
Other commands used were rail revolve, sweep 2 rails, patch, curve network, etc.Rebuild curve was used to get more or less accurate curves. Details were worked out separately on another plane and then pasted on the main model through a reference point. Central axis was a constant. Slab and pipe commands were also used wherever required. It was difficult to model flower shaped designs.
Polar array was also used. The overall model took about 5 – 6 hours in 2 days span. It is not very clean in terms of extra curves and surfaces, but that is a lesson to learn. It was a good exercise of modeling using a live example and 123D is a good application if used correctly.
