스마트 디바이스를 위한 3D 파라메트릭 CAD 시스템

Abstract

A 3D CAD system that can be used on a smart device is proposed. Smart devices are now apart of everyday life and also are widely being used in various industry domains. The proposed3D CAD system would allow modeling in a rapid and intuitive manner on a smart device whenan engineer makes a 3D model of a product while moving in an engineering site. There areseveral obstacles to develop a 3D CAD system on a smart device such as low computing powerand the small screen of smart devices, imprecise touch inputs, and transfer problems of created3D models between PCs and smart devices. The author discusses the system design of a 3DCAD system on a smart device. The selection of the modeling operations, the assignment oftouch gestures to these operations, and the construction of a geometric kernel for creating bothmeshes and a procedural CAD model are introduced. The proposed CAD system has beenimplemented for validation by user tests and to demonstrate case studies using test examples. Using the proposed system, it is possible to produce a 3D editable model swiftly and simply ina smart device environment to reduce design time of engineers.
