    • openAccess   Are we training our novices towards quality 2D profiles for 3D models? 

      González-Lluch, Carmen; Plumed, Raquel Springer (2019)
      In the history-based, feature-based, parametric CAD approach, 2D profile sketches are the basis for 3D models. Fully-constraining profiles is mandatory to create robust profiles. At present, neither CAD applications nor ...

    • openAccess   Comparative study of technical drawing methodologies for spatial vision training

      New technologies and computer-aided design (CAD) applications have changed the teaching of technical drawing in recent years, leading its study towards new paradigms. These paradigms have allowed the emergence of different ...

    • openAccess   CSG Feature Trees from Engineering Sketches of Polyhedral Shapes 

      Plumed, Raquel; Varley, Peter Ashley Clifford; Company, Pedro Eric Galin and Michael Wand (2014)
      We investigate the problem of determining design intent from engineering sketches: what did the designer have in mind when sketching a component? Specifically, we consider the unidirectional reverse mapping from form ...
