CAD 3D Model classification by Graph Neural Networks: A new approach based on STEP format. (arXiv:2210.16815v1 [cs.CV])

In this paper, we introduce a new approach for retrieval and classification
of 3D models that directly performs in the Computer-Aided Design (CAD) format
without any conversion to other representations like point clouds or meshes,
thus avoiding any loss of information. Among the various CAD formats, we
consider the widely used STEP extension, which represents a standard for
product manufacturing information. This particular format represents a 3D model
as a set of primitive elements such as surfaces and vertices linked …
