Os processos de projetação e construção de arquiteturas curvilíneas são ainda desafiadores. O uso de múltiplos aplicativos baseados em paradigmas distintos provavelmente não irá desaparecer. A interoperabilidade utilizada aqui foi não apenas a convencional. Foi também ‘ao vivo’, em tempo real, com os aplicativos abertos e rodando simultaneamente. Um fluxo de projeto baseado no uso aplicativos orientados para a criação da forma conectados via programação paramétrica e BIM foi proposto. O principal objetivo foi facilitar a projetação e construção de arquiteturas curvilíneas e suas estruturas de suporte utilizando simultaneamente dois diferentes paradigmas de projeto. As ferramentas ou operações necessárias nesta pesquisa foram essencialmente as seguintes: NURBS Lofting para a criação da superfície, contouring para o fatiamento modular da superfície e definição dos eixos geradores da estrutura em grelha, varredura ao longo de eixo para a criação de vigas perfil I curvas e panelização para a subdivisão das superfícies curvas em frações planares para viabilizar a fabricação e construção. No melhor do nosso conhecimento, a principal contribuição desta pesquisa reside na definição e desenvolvimento de um fluxo de trabalho e no desenvolvimento de novos algoritmos para facilitar a projetação de superfícies NURBS e suas estruturas de suporte correspondentes por meio de interoperabilidade em tempo real entre diferentes aplicativos.

description	The process of designing and building curvilinear architectures is still challenging. The use of multiple applications with distinctive design paradigms are unlikely to disappear. The interoperability used here was not only the conventional one. It was also ‘live’, in ‘real time’, with two of the applications involved opened and running simultaneously. A design workflow based on the use of form-forming applications connected via parametric programming to building information modeling, BIM, was proposed. The main objective was to facilitate designing and building curvilinear architectures and their supporting structures using simultaneously two different design paradigms. The tools needed in our research can be summarized as follows: NURBS Lofting for surface creation, contouring for modular slicing and structural axis grid definition, sweeping along axes for surface creation of the curved beams of I profile and paneling for the subdivision of curved surfaces into planar fractions. Parametric programming was used to automate sweeping along axes to generating curved I-beams and paneling to subdivide the NURBS surfaces into planar fractions. To the best of our knowledge, our major contribution resides in defining a workflow and developing new algorithms for facilitating designing NURBS surfaces and corresponding supporting structures through ‘live’ interoperability among different applications.
