This was my 3rd project whilst studying naval architecture. It calculates tank volume and inertia using cubic splines. It had a really basic shell definition algorithm. After you define shell you need to create tanks using Aft, Forward, Top and Bottom values. Software automatically trim geometry using outer shell. Unfortunately it can only be used for simple geometry. You can’t create complex geometries with this software.
Here are some screenshots:
Now, i work in the design industry and i know this simple geometries are hard to see. So i am planning to make a revision with the code, so that it will accept solid geometries.
