Whilst there are still so many variables to consider and decide on, there is one thing I can be doing one thing that is definitely needed and highly unlikely to change, and that is the space shuttle.
I've decided to build the space shuttle Atlantis from NASA. It may change slightly but for now it is a great base to build on, and thankfully I was able to find fairly clean 'blue prints' of it from
http://www.the-blueprints.com/ .
Started the build, only creating half and eventually mirroring it as the shuttle is almost a perfect mirror image of itself if split in half.
This is my second attempt at the build, this time I am using a modular approach; breaking the shuttle into pieces, building them and then placing them back together.
Modular creation is just one way to go about building anything in 3D. For me it is slightly easier for the level I am at with the use of 3D software. It may take longer than other approaches, but it makes the most sense to me at the moment. I know I will have to attach them together further down the line and then clean the hole mesh topology up.
