i'm a professional jewelsmith and 3d jewellery designer.all my digital jewellery models and renders are suitable for client presentations. they are in the 3dm (rhinoceros) file format. they can be opened, viewed, rotated, studied and measured with rhinoceros3d software. my models can be used for rapid prototyping and cnc wax milling. my digital models are also a useful visual assist for traditional wax carvers. precise, orthogonal and perspective views of 3d digital models, printed at 1:1 scale on paper and tranparencies are very helpful for layout and visualization in traditional wax carving.
