The proposed approach in the paper is dedicated to enrichment of CAD models storage in
PLM (Product Lifecycle Management) systems or archive databases. The paper considers …

Digital twin (DT) technology enables the creation of DT that are synchronized with the state
and behavior of physical entities. DT simulates physical entities, which can enable the …

Generating an up-to-date BIM that accurately reflects as-built conditions is becoming
necessary for ensuring fit between assemblies and construction sites. If an initial BIM (“proto …

In this paper, a point cloud coarse–fine registration method based on a new improved
version of the whale optimization algorithm (NIWOA) and iterative closest point (ICP) …

A model simplification technique is required to control the level of detail (LOD) of a three-
dimensional (3D) computer-aided design (CAD) model. In particular, to simplify a B-rep …

The dimensional accuracy of additively manufactured (3D printed) medical models can be
affected by various parameters. Although different methods are used to evaluate the …

In the shipbuilding industry, it is difficult to create CAD models of existing or prototype parts,
especially with many freeform surfaces. The paper presents the creation of the CAD 3D …

This paper introduces a new fitting approach to allow an efficient part-by-part reconstruction
or update of editable CAD models fitting the point cloud of a digitized mechanical parts' …

X-ray photon correlation spectroscopy (XPCS) is a powerful tool in the investigation of
dynamics covering a broad time and length scale. It has been widely used to probe …

Aiming at solving the problems of small footage, easy skid and immovability of milling during
the process of milling multistage fracturing ball seats by milling tools, and considering …
