Autodesk Alias Studio Tutorial – Rear Spoiler

Both the vent and the BIG spoiler are done with thw Alias Poroportional Modification Tool

I have been away on other projects, so my Porsche Carrera Turbo Special Body Kit type exterior has been on the back boiler

Rear Spoiler Appears

As you can see I’ve gone mad and created a rear spoiler. I personally made the clay model for the Audi TT rear spoiler back in 1999. Rear spoilers are tricky beasts. There are no datum surfaces to measure from, but us Alias modellers live in that crazy world.

How to start

Make an ellipses in the top view and project it onto the body where you want your spoiler uprights to stem from.

Make a smaller ellipse and move it vertically up and back a bit from the base c-o-s. Run a skin surface between these 2 ellipses to surface your supports.

Build 3 cross section curves for your  spoiler wing . That’s 1 on the LHS, 1 on Y0 and mirroe the LHS over to form no. 3 on the RHS. Now skin the 3 curve sets hold down shift for the 3rd one.

Close the open ends of the wing off with a planar surface or a surface which is appropriate for your model.

Top view, project an trim divide to form the movable aileron and allocate a different shader to it. I have a 3mm parting line , but you can’t see it in the little jpeg.

However complicated the surface intersection of say a spoiler or mirror maybe, I always start by projecting curves onto the parent surface to for c-o-s to build from.

NB: I’m still on the most basic wheels possible. Just like designing a car exterior in the automotive industry, where the only import thing about the wheels for the first few years of a project is the dimensions. The wheels ate the icing on the cake and come last.
