Abstract:

The present study is divided in two constructive ways: conversion of volumetric bodies constituted by polygonal surfaces (quads) into surfaces NURBS and conformation of patterns or other polygonal entities on such volumetric bodies. There are numerous cases where the target topology cannot be converted to a single and unique NURBS surface, a procedure that would make the task of volumetric transposition easier and which would already be solved by the use of ready made parametric modeling tools. To carry out this article's tasks, generative modeling systems and associative parametrization strategies were adopted. The knowledge for the construction of the systems used in the present research can be used in different fields that have, as a paradigm, the design creativity as one of its beacons, such as Visual Arts, Architecture and Design. The present work aims to make use of digital manufacturing through laser cutting, 3D printing or CNC milling technologies, at the same time expanding strategies.
