Sažetak
This paper proposes an approach for computer-aided SD of exact global reflection and axisymmetry in B-rep CAD models. Our proposed SD approach is not restricted to only 5 analytical surfaces (plane, cylinder, cone, sphere, & torus) like in the prior research, but it also considers other numerical surfaces such as blend surface, B-spline surface, and surface of revolution. During validation, the proposed SD approach confirmed that it enables accurate and computationally efficient detection of the POS/AOS. The future research will be focused on the following points: (i) extending the testing to a larger number of CAD models and other types of mechanical parts (e.g., sheet metal, forged, cast, etc.), (ii) extending the number of the candidates for the POS as in some cases mechanical parts can have more than three POS, and (iii) extending the approach to cyclic and partial symmetry.
