For the last week or so I have been muddling around with Autodesk's free web ap "Tinker Cad". It has been very easy to learn and use. I will probably move to a more sophisticated (free) program soon, as the control over the shapes/nodes are lacking.
Following is one of the 3D dodads I have been working on . This is a modular component for the existing capitol ships for the game Battlefleet Gothic. I am also working on other pieces for the game such as variant torpedoes, variant fighter craft, and other accessories.
This is a launch bay component. The motivation for this piece came from not liking the bit that comes with the original models, and the inspiration came from the middle section of a transport ship (see below). I always liked the design although it never looked right to me as a transport ship.
These are the components from a heavy transport ship. The second piece from the left was the inspiration for launch bay project. The two types of cargo bays here are 'troops' and 'fuel'.
Here is a sketch for the component I am planning of a 'spine' midsection that will receive modular cargo components. It will also be compatible with the weapon components from the original models allowing for merchant war ships.
Adeptus-B and I discussed making some steam-punk conversion pieces for building and figures. Eventually, I would also like to design some custom game pieces for my Monopoly Omega and Risk Omega projects.
