Sketching is a natural and intuitive communication tool used for expressing concepts or
ideas which are difficult to communicate through text or speech alone. Sketching is therefore …

The problem of identifying the topology implied by wireframe drawings of polyhedral objects
requires the identification of face loops, loops of edges which correspond to a face in the …

Featured Application This work examines the detection of dashed lines in engineering
sketches, a subproblem of the more ambitious challenge of automating the reconstruction of …

Numerical controlled workshop has 10 sets of CNC equipment and CAD/CAPP/CAM center,
the problem is how to implement information management. This paper applied ZNE-100TL …

This paper focuses on the identification of hidden lines and junctions from natural sketches
of drawings that exhibit an extended-trihedral geometry. Identification of hidden lines and …

In this paper, the authors present a new algorithm for constructing a solid model when the
given input is only one partial-view sketch (“natural sketch”). This algorithm is a two-step …

Humans have the ability to easily recognize 3D shape from a given sketch. On the contrary,
a computer program requires mathematical criteria to establish if a sketch is realizable, ie, if …

This paper introduces an optimization strategy for evaluating the realizability of a 2D
wireframe sketch that conveys geometric and topological information about a 3D solid …

As part of a strategy for creating 3D models of engineering objects from sketched input, we
attempt to identify design features, geometrical structures within objects with a functional …
