Description

  The present invention relates to a building area calculation apparatus and method for calculating a building area, for example, a floor area.

  When obtaining a desired location on a CAD drawing, for example, the floor area of a room, the edge of the wall of the room is traced with a mouse, and the area is obtained by a predetermined arithmetic expression based on a numerical value obtained on a computer. It was.

  Therefore, as shown in Patent Document 1 shown in FIG. 6, the mouse pointer is placed on a point (top) using a CAD drawing, clicked, and the mouse pointer is moved to the position of the point (end) while keeping the clicked state. After moving, the click state is released. Then, a rectangle having the same shape as the living room can be recognized, and the area can be calculated on the computer. Depending on the shape of the room, some of the rooms may be triangular and cannot always be divided into rectangles. Therefore, as shown in Patent Document 1, the area cannot be calculated simply by moving the mouse pointer diagonally. This method is based on the end of the living room and calculates from end to end.

  In architectural drawings, the building area refers to the horizontal projected area of the building (the floor area seen from above), and the total floor area refers to the total floor area of each floor. Center line). Therefore, it is customary that drawings are written based on pillars and wall cores.

  In addition, as in the conventional example, the diagonal direction of the rectangle is traced, so tracing the edge of the living room with the mouse pointer will measure between the opposite sides on the screen, and will trace each side. There is a possibility that an error may be included in the measurement, and the calculation is complicated.
