Configuring complex computer-aided design (CAD) assemblies just by modifying parameters requires the attention and abstraction of the users. This interaction cost can be lowered significantly by graphical interactive control elements that allow for drag and drop modifications directly in the 3D assembly. Contributing techniques, such as working with skeletons and advanced or external knowledge-based parameter control, are available. This contribution examines their integration and implementation into a given CAD system through a case study on creating a pipe routing configuration system which uses drag points to adjust the position of instrumentation and routing segments. The results are then generalized to functional requirements and basic design features of such graphical interactive configurators.

“…It has certain advantages in outlining the shape of the blade tip. Tang et al [32] presented a decision-support method for multi-parameter editing of parametric CAD models. The method supports decision-making in multi-parameter model editing by calculating the allowable parameter range, assists users in realizing model editing, and ensures the solvability of the geometric constraint system.…”

The digital model of airborne frequency selective surface radomes (AFSSRs) is the basis of design, simulation analysis, manufacturing, and other related research on AFSSRs. This paper proposes a rapid modeling method for AFSSRs based on dynamic customizable primitives. Firstly, a layered digital model construction scheme for AFSSRs is presented based on the typical radome wall structure. Then, according to the characteristics of various surface configurations and the complex wireframe information of AFSSRs, the dynamic primitives are raised to express the boundary and contour information of all kinds of radomes. Focusing on the undevelopable characteristics of the aerodynamic shape surface of the AFSSR, the arrangement solution and mapping method for frequency-selective elements on undevelopable surfaces are proposed. Furthermore, the implementation logic of this method for the creation of each layer model and the assembly of the whole machine model is introduced. Finally, a rapid modeling system (RMS) is established based on this method, enabling the automated creation of digital models of AFSSRs. Utilizing this system resulted in modeling time savings ranging from 20% to 97.5% compared to traditional methods, which verifies the feasibility and effectiveness of this method.
