Deformation of CAD surface models in real time environmnet for product design and development using CUSUMA tool

Abstract

This paper provides a novel tool for a generation of complex surfaces based on computer-assisted design for various applications like aerodynamic shape design in airplanes, ships, cars, scooters, mopeds and also in industrial product design and development. The proposed tool can be used for generation of the intricate surfaces of any product by manipulating any number of control points.The product designer can select any number of control points before actually drawing and finalizing the shape of the desired object. The curve is first drawn using CUSUMA, A GUI and then import it in any cad software. The designer can add, remove and manipulate the control points to achieve the accuracy of desired shape in early design stage. In designing any complicated shape where accuracy plays an important role, the designer can use proposed profile curve management technique (PCMT). The ultimate aim is to generate the desired shape by plotting the model using the platform and then manipulation of any number of control points in real time by pushing, pulling, dragging, adding and removing it.
