We require a artistic impression to show a client. the drawing is of a metal structure with a fabric roof,please look at the carapax and the dalo web site, these will show you the rough outline of the structure. The structure is supported by a metal frame, which also forms a partition, which is infilled with plastic glass. If you feel that this is the type of project that you could easily do, then we could move on to cad drawings. I have a writen a synopsis and have some pretty amateurish sketches.
