Many vehicles today have ergonomically designed steering wheels
making the modelers job challenging. This steering wheel dims. are: Major axis = 356.4mm, Minor axis = 330 mm.
Egg Shaped Xsec
this means that geometry for the rear half of the wheel cannot be symmetrically created. The front half is itself elliptical in xsec. and the rear half is elliptical but has a lot more peak, in order to make the wheel more ergonomic to grip
Fabric Trim Seams are used to catch the eye and gain asethetic quality.
These align with the central hub of the steering wheel (not shown here)
Seams are important to the Interior Designer
and must be modeled as accurately as possible
Lattice Rig
Just in from Karin Mayer today this nice pic of her WIP. Bezier Steering Wheel
The entire Yolk (Hub & Spokes) employ Bezier srfs. apart from the tertiary blends. I teach my students to work to Class A “Principals” as much as possible. The reason being that there are a lot of young modelers looking for entry level Automotive jobs and very few who can work reasonably quickly using Bezier srfs.All my Private students manage to get jobs and the feedback I get from employers, is that students who understand the principles of creating an A Class model are valid a lot more.
Karin has used the Lattice Rig to fine tune the proportions of the 3 spokes
Bezier Blend Patches
After employing the FF Blend control to create her original transitions , Karin has deleted the Nurbs patches and replaced them with Bezier Square surfaces. This is what is demanded on most Automotive projects
Transition Surface Looks Smooth
BUT, this is still a WIP and the Designer would want a softer look to the transition. We can see that the xsec of the trans. srf. looks flat, so either the curves need to be adjusted or the patches need to be direct modeled to add more peak. Nevertheless, the steering wheel is a beautiful piece of Bezier modeling
Pic just in from Karin
She has completely re-built the transition using Nurbs crvs and Square patches. She used deg 6 crvs. which provide
a spare CV to adjust the peak of the blend
Videos showing this workflow come from the video library I have been creating for the past 2 years, now standing at some 250 individual, unique videos and can be accessed by students who subscribe to my website. We are proud to say that we have LearningAlias students in many OEM’s, including: Lotus, Ferrari, Fiat, GM and perhaps soon at Audi too! We also train Alias Modelers, who are in the first year of there Automotive Career

To Learn Alias Automotive to Industry Entry level has been made easier.
For student’s who have the objective of finding a CAD job in the near future, I still teach One to One students and all of these students get Automotive Modeling or Design/Modeling jobs, so it’s a great investment to make. The hourly rate is very high and there are vacancies in UK. France, Germany, Sweden, Spain, USA, Brazil etc. I can only take a maximum of 5-7 students at any one time. I teach all levels right up to Post Graduates. I have never had a Private student fail to get an Alias Automotive job (Companies include Ferrari, GM, Lotus, Opel, Audi Seat etc. ). If you wish to apply for a place, please email me with all your details.
Why not visit my website and take a look for your self?
Over 100 videos on many, many aspects of Learning Pro. Alias
I show you how to build a Complete Audi A5 Sportback (ext.) . Over 50 Videos on that alone !

Fast Track Full Pro. “One to One” Course with weekly reviews and coaching 200-250 Euros (USD. 260-320 approx. Sept. 2012) per month. One to One Private tuition. You will receive specific geometry and meshes and modeling from me personally where required, to help you to complete your exteriors quickly to an Industry entry level standard. This means a bigger investment, but once in an Alias modeling job you will get back what you invested many times over and be able to work anywhere in the world
NB: Typically students pay 50% of the cost of the “Elite” course by monthly installments settling the balance over time, once they have an Alias Automotive contract.
