Hi! I was trying to build a very simple set - http://peeron.com/inv/sets/1749-1 I started with LDD but there is no Tile 1 x 2 with Underwater Navigation Pattern in it So, I tried LDraw (MLcad and LEOCad), and I found that part, but I didn't find this and this and this and this...and I stopped. That's a very small and simple set, but a lot of parts are missing, making impossible modelling this set ((( How can I solve the problem? Creating missing parts by myself? If so, how can I do this?
