AAT Battle Tank Model

The base of the AAT Battle Tank was created by scaling a a sphere to make it a disk shape. From this shape I used the boolean difference tool to remove the bottom half of the sphere. For the torpedo bays on the sphere I again used the boolean difference tool. One of the main issues with this method was trying to place the torpedo bays symmetrical on either side of the base. I resolved this by placing the base on the "0,0,0" co-ordinates and using the translate to place them precisely. For the gap at the bottom of the base I used the boolean difference tool with a large cube. The only issue I would change with the base is the end torpedo holes, because of the height and the positioning of the torpedo bay the hole removed too much off the top of the base. I had issues trying to remove the boolean difference effect and is a skill I will endeavour to learn.

The top entrance hatch of the AAT Battle Tank was created by simply combining spheres and cylinders and using the boolean union tool to join those objects together to form 1 object. I chose to use the boolean union tool over grouping them to reduce the total amount of polygon's in object making it more efficient. For the main turret hinge I created cylinder and moved the edges and vertices to create a hinge like shape.

The main body of the AAT Battle Tank is a mix of curves and straight lines, I found the body to be the most challenging part of creating the model because of this. I tried a few different techniques to achieve the final result. The first attempt I tried was making a square in the rough shape that the main body needed to be in and then used the mesh smoothing tool to give it a more rounded shape. This technique however did not get the results I was looking for, although it was a smooth shape it did not fully capture the shape i was after and used far to many polygons to justify the end result.

The second technique I attempted was creating the same rough shape as in the first attempt but using the bevel tool on the two front edges to give it a curved front. I believe this was the more accurate looking result and used far less polygons to achieve it. For the main Turret I also created a Bay with in the two hinges, for this I used the add segments and face extrude tools. 

 The detail such as the smaller side turrets and the Front guns and icon were all created by combining cylinders and cubes. From this I then used the boolean union tool to create them into whole larger objects, again this was to reduce the over all polygon count and make it a more efficient model

Here is the final result.....
