One of the design consideration is to be scalable. How to achieve this has not been easy. Using 3D software has made it a lot easier however. By designing a base shape which can then be manipulated to change dimensions has been a great way for me to work. After final shape and dimensions have been finalised the shape is then unfolded in the programme to get a 'flat' version which can then be cut out onto the coroplast. I intend to mock-up a 1/2 size model just to check that everything will fit and work with the coroplast. It is also a chance to "tweak" the design.
