A decision-support method for multi-parameter editing of parametric CAD models

2023, CAD Computer Aided DesignCitation Excerpt :Nevertheless, before checking degenerated face configurations, they first identify boundary faces affected by the modeling operation to reduce checking time (to be called the culling idea). In this work, the heuristics developed in [12] and the idea presented in [43,44] have been combined to implement the GTIP detection module. We do not use the culling idea to accelerate GTIP detection but to handle global GTIs.
Propagating Design Updates to Structured Analysis Meshes
2022, CAD Computer Aided DesignCitation Excerpt :Parametric perturbations can induce changes in the boundary topology of a B-Rep model. To this extent, Van Der Meiden and Bronsvoort have defined a method to relate the range of parameters to the boundary topology of a B-Rep model, therefore identifying critical parameters of interest [22]. Sun et al. have proposed a method using virtual topology to move a surface mesh in the presence of simple boundary topology changes, by applying virtual topology operations on both models to produced two models with matching boundary topologies [23].

2017, CAD Computer Aided DesignCitation Excerpt :In this regard, knowing the range where topology does not change is important. Authors van der Meiden et al. presented a method to compute the critical values when a single parameter of a model is modified, (i.e. the parameter values for which the topology of the model changes) [136]. Accordingly, MQT tools could simply highlight those parameters that are particularly sensitive to changes, making explicit where a model is robust but barely flexible.
On the long-term retention of geometry-centric digital engineering artifacts
2011, CAD Computer Aided DesignCitation Excerpt :The principle drivers for these developments are nearly always to enable near-term advancement and the development of new geometry-centric modeling tools and semantically consistent feature-based operations on these models. Readers interested in more detail on these topics are referred to the following recent and seminal papers on geometry representations and feature-based modeling [11,12,50,8,51,45,52,3,6,5,53–56].
