Efficient support of graphical and spatial 3D design using computers needs a user interface that incorporates easy manipulation of 3D information, integrated phases of manipulation and estimation, and continuous modifications of 3D information. To achieve this, the Binding Box Model was proposed, in which 3 D graphical and spatial information is represented by spatial units and their bindings. The model enabled manipulation of 3 D graphical and spatial data based on perspective projection drawing. A prototype system implementing this concept was developed to identify the advantages and disadvantages of that model.

The class of “Space Media” is opened for the third grade of the architecture course. This class is the practice for learning of CAD (Computer Aided Design) and Image processing CG (Computer Graphics) technology for architectural design. The CAD/CG use in the architecture course has a character as a media of design presentation. Therefore, it aims at learning of not only the drawing skill but also the presentation skill as well. It was started from 2004 that using new some softwares, step-up reports for design theme and management rules of class corresponding a large number of student. Compared with the class of former year, students' level of design presentation has got up clearly in the class of 2004. In this paper, we report aims of “pace Media” and abstracts of the class first, and showed some students' final reports of space object design next. Consideration about the effectives of our new trial is reported finally.

In order to obtain the information about visualization ability for architectural drawing of university Laotian students in Lao PDR, PIT (Plan Interpretation Test) [4] is applied to Laotian students of Fundamental course and Architecture course in Lao PDR. The results are as follows : (1) For PIT, the score of Laotian students in architecture course and that of freshman of fundamental course of Osaka University are almost the same. Another score of the other groups of Laotian students except students in architecture course are low significant compared with those of them. (2) In Laotian students of architecture course and Japanese freshman of fundamental course with the high average score of PIT are more difficult to visualize exterior space compared with visualizing in interior space, but in the other groups with the low average score of PIT are difficult to visualize in both spaces (3) As the variation ranking of correct answer rate in each problem of AECS 1 and FCS 1-J with the high average score are almost found same tendency. (4) Laotian students who have professional education in architecture are able to judge on multiple floors plan of architectural drawing, others it has found that students who have no professional education in architecture are able to judge only information on a floor plan view.
