Blocking Out The Tram
I have blocked out the outer part of my tram in Maya - this is to give myself an idea of what it will look like and the size / scale of it.
I started with a cube and used the multicut tool to create points I could manipulate on the model. Using the move, scale and extrude tools I created the Tram shape.
Blocking out a model first is a useful practice because it means you can see what your model will look like in a 3D space and are able to work out spacial and geometrical errors or changes before the model becomes too complicated. It gives you a basic idea of how the model will look.
