designIT is a software tool for all building practitioners for the design of CHH's Engineered Wood Products range and other selected materials for floor, roof and wall framing in houses and similar structures. Quick and simple to use yet deceptively powerful software, designIT is useful for the selection of beam sizes without the need for engineering knowledge or the exercise of professional engineering judgement. |
Layup is an ArchiCAD add-on (available for most recent versions) developed to aid specifiers in the fast and simple production of joist and rafter layouts. It is one of the integral design components of the Superior Performance Flooring System, FLOORSUITE. Once the layout is drawn up a simple click of the mouse will label, calculate and produce a schedule of quantities to be used by merchants making ordering and delivery of components a breeze. |
