<p>PURPOSE:To efficiently and automatically allot the hut beam supporting the joint part or intermediate part of the roof panel arranged to a roof surface when the roof of a building constructed from a panel is planned by a CAD system. CONSTITUTION:A shape memory means (I) stores a planned roof as a plan and the reference lines determining the positions of the hut beams supporting a roof panel are formed to the roof surface on the plan read from the shape memory means (I). That is, the reference lines showing the positions of the hut beams are formed by a reference line forming means (II) so as to provide a specific interval in the inclined direction of the roof surface. Then, the kind, arranging direction and positions of the hut beams are determined along the reference lines on the plan by a hut beam-allotting means (III).</p> |
