TLDR
A two-step similarity comparison method for B-rep files is proposed and overall appearances are compared first, and then detailed features are compared so that existing parts with similar feature set in addition to similar overall shape can be identified from the part library.Abstract:
In actual practice, many new mechanical parts are designed by modifying existing ones In this way, time and effort can be saved by not having to design parts from scratch Design time would be further reduced if there were an efficient way to search for existing similar designs Furthermore, a new part design can be very efficiently generated by modifying the dimensions on the features of the existing part if a part with a similar feature set and the corresponding modeling history can be easily searched from the existing part library In this paper, a two-step similarity comparison method for B-rep files is proposed Overall appearances are compared first, and then detailed features are compared In this way, existing parts with similar feature set in addition to similar overall shape can be identified from the part library Once the similar part is identified, its modeling history can also be used for parametric modeling if the existing part was designed by a feature-based modelerread more

Reverse innovative design - an integrated product design methodology
TL;DR: This paper proposes a reverse engineering innovative design methodology called Reverse Innovative Design (RID), and introduces three RE modelling strategies: an autosurfacing strategy for organic shapes; a solid modelling strategy with feature recognition and surface fitting for analytical models; and a curve-based modelling strategy for accurate reverse modelling.

A survey on 3D CAD model quality assurance and testing tools
TL;DR: It is shown that low semantic level errors that hamper simplification are reasonably covered in explicit representations, although many CAD quality testers are still unaffordable for Small and Medium Enterprises, both in terms of cost and training time.

Topology matching for fully automatic similarity estimation of 3D shapes
TL;DR: A novel technique is proposed, called Topology Matching, in which similarity between polyhedral models is quickly, accurately, and automatically calculated by comparing Multiresolutional Reeb Graphs (MRGs), which operates well as a search key for 3D shape data sets.

Matching 3D models with shape distributions
TL;DR: The primary motivation for this approach is to reduce the shape matching problem to the comparison of probability distributions, which is simpler than traditional shape matching methods that require pose registration, feature correspondence or model fitting.

Indexing using a spectral encoding of topological structure
TL;DR: An indexing mechanism that maps the topological structure of a tree into a low-dimensional vector space based on a novel eigenvalue characterization of a trees allows us to efficiently retrieve a small set of candidates from a database of models.
