BIM is an abbreviation for Building Information Modeling. This is a new workflow that adds various attribute data to a 3D building model and allows the building database to be used in all processes. Home equipment manufacturers' homepages now provide BIM data with various attributes in addition to 3D data that merely represents the shape. The use of the BIM model facilitates image sharing and facilitates communication between stakeholders. We can produce ARCHICAD, REVIT new construction, temporary scaffold model, family GDL, etc. We have a system for mass production at low cost。
