In the field of CAD (Computer-Aided Design), there has been
some effort to apply recent technology i.e., smart and ubiquitous technology. It is expected that mobile communications, ubiquitous sensing and computing technology, smart reasoning and
agent-based computing, natural interaction techniques and other
such technology will play a part in forming the paradigm of
next-generation CAD/E systems and environments [3]. Thus, various studies of CAD have been done in recent years.
