The purpose is to evaluate models obtained by different 3D scanning systems, and that the geometric variations can generate implications for anthropometric measurements for custom product design. For comparison and analysis, the right leg of a subject was scanned by white light 3D scanner (Artec Eva) and the infrared scanner (Microsoft Kinect). 3D models obtained by the scanners were compared using the Geomagic Qualify software. Also, by CNC machining of visual comparisons were performed analysis, for pressure mapping and thermography. The results were satisfactory both for the use of Kinect scanner and for Artec Eve. However, there was a dimensional difference of about 7 mm between the 3D models, which shows higher accuracy measures the models obtained by Eve Artec scanner. However, does not invalidate the use of Kinect for developing custom product designs. What will determine the most suitable for each type 3D scanner product is the degree of accuracy necessary for the product to perform its function with greater comfort and efficiency.

The present study focused on the inclusion of visually impaired individuals in regular and special
need education based on the proposal of educational resources to be applied in different
disciplines. This study case involved the development of models of nanostructured systems. The
production of these models included image design and stylization, 3D virtual modeling and 3D
print. The representation techniques used in this study generated a didactic kit for the teaching of
nanostructured systems. The proposed models can be used for both sighted and visually impaired
students, whether blind or with low vision.

Este trabalho apresenta o desenvolvimento de um produto baseado nos conceitos de modelagem paramétrica e fabricação digital. Tais conceitos trazem consigo a possibilidade de otimizar os recursos investidos no processo de design, aumentando a produtividade, além de agilizar as fases de prototipagem e de ajuste do projeto. A partir de um problema proposto: diminuir as grandes perdas causadas pelo desperdício de alimentos na fase de pós-produção, o produto desenvolvido ao longo desta pesquisa é uma embalagem para o transporte de frutas. Para a geração de ideias foi utilizado o jogo Creative Sketch, desenvolvido por Cardozo (2012), e a modelagem paramétrica, realizada no software Rhinoceros 3D com o plugin Grasshopper.

This paper presents the main contributions of the research group Virtual Design (ViD) on the learning process of Descriptive Geometry (DG), in line with the principles of project-based learning. First, the paper presents the theoretical framework for the main ViD initiatives applied to the learning of DG, including design-based learning and physical and virtual modelling. The initiatives presented include a learning cycle based on concrete and virtual experiences in the design context. These initiatives, that feed the learning of DG, are the result of the academic research of the Virtual Design research group, that also involves Masters and PhD projects, with repercussions on the development of new methods, new technologies and new products and the quality of education.
