3.2 Drawing Elevation 
The work procedure for creating a north-side elevation is 
introduced. The data of area required to create this elevation 
were compounded on CAD and then the hidden part's data were 
deleted. All the things that were visible through opened areas 
were drawn. In order to express depth, as shown below, the 
thickness of lines were classified. The nearest layer was drawn 
in 0.25mm and the next layer was drawn in 0.15mm.

3.3 Coordinate Management System 
Data was stored in the coordinates management system, in 
order to display each elevation, each sectional view (a total of 
20 drawings) and to search simply the three-dimensional 
coordinates value (global coordinates) of each point. On the 
drawing, actually, it turns out that corner 1,2 of the brick that 
seems to exist on the same plane is located in the different 
surface of the wall. 
However, on an actual structure, the position chosen by the 
system is not set up, so that point cannot be specified. As the 
result, the out-line position was used.
