Organic Modeling Techniques
The previous chapter introduced a variety of solid-modeling techniques that use polylines, extrusions, and predefined primitives in 123D Design. These basic modeling methods allow 3D-print designers to input precise measurements for developing well-engineered 3D models, providing the assurance that the parts being created work exactly as expected. But 3D printing isn’t strictly intended for engineered parts. For many artists, the freedom of creation enabled by 3D printing offers the opportunity to manifest visually compelling sculptures, abstract shapes, and free-flowing forms. Using solid-modeling techniques to construct such highly organic forms presents a challenge. When using solid-modeling methods to create complex, flowing, and organic designs (such as an abstract sculpture), every curve has to be strategically placed, point-by-point, and the adherence to such precision can be extremely time-consuming. For many designers and artists, 3D printing offers an opportunity for visual experimentation and the constant use of exact measurements and precisely placed curves are not always necessary.
