DESIGN SUPPORT DEVICE

PURPOSE: To provide a design support device which can easily confirm the positions, etc., of the upper and lower stories having a structural connection based on the drawing of one story in regard of a building consisting of plural stories which are structurally connected to each other. CONSTITUTION: For instance, the plan of a roof consisting of plural roof panels 16 is outputted to a design support device as a plan of anyone story. In this roof, the joint part of wall panels constructing an outer wall 12 is joined to the vertical core member put at the center of the panel 16 when the roof is joined to the wall 12. In this instance, the joint parts of wall panels forming a wall under the roof are shown on the plan of the panel 16 as the V marks 18. Thereby, it is possible to decide the position of the joint member that joins the roof to the wall 12 based an only the plan and without referring to a drawing that shows the arrangement of wall panels of a lower story.
