I trimmed away the sides in order to build the DLO area. I later decided I didnt like the result I was getting and rebuilt it.

This was where It started gettin gnasty. The square surfacing that was put in just had way too many spans and did not illustrate the form I intended. So I deleted it.

And I put in this. I used a centerline on the side of the car to pull the window out further. It really more illustrates my design intention. It will be replaced with one span of surfacing next.
I also am going to be getting rid of the tic-tac-toe front end.

Still working on the Alias model.

Im not very satisfied with the rear fenders, but at this point, I am just blocking stuff in. It will definitly get changed in the future. the chopped up sqares in the front end will be going as well. it just not a good idea to have that many surfaces taking up something that really only needs 1 or 2.

by using the zebra coloring, I am able to analyze the surfaces to ensure prefect curvature continuity throughout. I also use it to see how the surfaces will react to reflections. where the zebra stripes run wacky, the reflections will look weird, even if there is perfect surface continuity.

I have started constructing the vehicle in Alias based on the side view and some other sketches I have done. I will be uploading those in a little while.
Creating a 3d model of the car is much more difficult than anything I have ever tried. You must know how you want each and every surface to interact with eachother. On top of that, creating the surfacing so it provides a beautiful render is even more difficult. There are NO sharp corners anywhere, and EVERYTHING has a fillet, however small it may be.
I am definitly going to be rebuilding the front fender, it is nothing like what I have sketched or intended, but creating this basic model is just like sketching, where you have to communicate your ideas and evolve the form until you get what you desire.
This is just an extra dimension to worry about.

These are the omnidirectional wheels. Notice the diagonal treads. They act as teeth to propel the vehicle sideways if wanted. By alternating the rate at which the wheels spin, the vehicle will turn, and by alternating the direction in which they spin can make the car move laterally for parking purposes.
Well, I was having a tough time trying to develop a profile for my vehicle that is interesting. I am using the Audi quattro from the 80's as an inspiration, I figure that a sports car that sits higher is much easier for people to get into and out of than a low one. It also fits better over a Cadillac CTS package and provides answers to some logistical issues that lower cars encounter such as speed bumps and steep inclines.
This vehicle is as long as a 2008 Cadillac CTS but sits a bit higher and has a longer wheelbase.
Wheel design is coming up next.

I have been having a difficult time over the past few weeks developing a profile for the Cadillac Studio that I am currently participating in. This is a few select sketches that Have been done trying to develop a concept. I have decided to go with the "wrap" feature illustrated in the first sketch as a way to use some vintage cadillac covered wheel inspiration.
I know what you're all thinking, "how does it turn?" Well, a solution has presented itself in the form of omnidirectional wheels. They are used primairly on forklifts other heavy moving equipment. Each wheel is like a conical gear which spins either clockwise or counter in order to propel the vehicle in the desired direction.
