Abstract
Introduction consideration of a CIM is accomplished as utilization of IT to a construction production process (ICT) in our country in recent years. As a result data profit utilization of three-dimensional model of the construction field has started. The three-dimensional model to which attribute information was given is to be utilized in a construction life cycle, and improvement of the productivity of the whole construction business is expected. For the moment, I design at both of three dimensions and two dimensions. Therefore designer's work rate isn't reduced. This study will report the result which considered a drawing of the usual method and the way to calculate the quantity from a 3D model.
