Most geometrical modelers for 3D objects use 2D interaction techniques and make little use of 3D display techniques. This interaction style forces the user to decompose 3D design operations into sequences of 2D interface operations, and there is an extra cognitive load of interpreting the 2D displays as a 3D object. While this may be acceptable for drafting applications, it has a significant ne...

A Response surface design of experiment has been performed based on the Muschelknautz method of modeling (MM) for 64 test cases using Box-Behnken design to study the effect of seven geometrical cyclone dimensions on the pressure drop and cut-off diameter. It is found that the most significant geometrical parameters are, the vortex finder diameter, the inlet section width and height, and the cyc...

In this paper, a systematic approach is presented for optimal design of tunnel support lining using two-dimensional finite element analysis models of soil-structure interaction developed in ABAQUS software and the Modified Colliding Bodies Optimization (MCBO) algorithm implemented in MATLAB environment. This approach is then employed to study the influence of variable geometrical and geo-mechan...

In medical and surgery applications, the implant design is the key. Any mismatch in the implant design results in the implant failure as well as psychological stress and pain to the patient. Measuring and inspecting the geometrical implant design with the reference model is very important, to ensure the proper fitting and safety of the patient. The purpose of this study is to perform the evalua...

When dealing with muqarnas, we are actually facing a design problem that consists of three main issues that has to be considered; first is the components, second is the assembly knowledge, and finally functional knowledge. In this context Design Procedures (DP) is presented as a methodology that enhances the design capability of a parametric model to perform design variations by using shapes as...
