Nepal: Please Join my action to raise money for people
sleeping rough in Nepal following the devastation of the Earthquake. Please donate just 10-30 GBP/
15$ to 45 $ Why not take 2 min to do it now?
Learning Alias sponsors the Education of children in Nepal. But right
now we need to raise money quickly to send to her village Khiji Chandeshwori, which is in the foot
hills of Mount Everest. 7 homes in this small village 2 days walk from the nearest road, have need
completely destroyed and the families are sleeping under plastic in the rain and cold. However much
is collected up to 1000 GBP ,LearningAlias will double. Thank You for your kindness, graham

I am now putting some of my tutorials on YouTube, so whilst you’re there you may wish to check them out. There’s a full tutorial on how to create a Ball Corner to Class A Surfacing, Catia V5 spec.

Audi A5 Hood & Fender Top Surfs

The hood is a class A surface, but if we study the 2 fender top surfs we can see that the larger one is not very good internally

Analyzing Surface Internals with Dynamic Section Cont.

Because surf#2 is having to do so much work, its smoothness is bound to break down, resulting in very poor internal surface quality

I have put in 4 x-secs using Dynamic Sect. Cont.The hood is perfect, as it’s a Class A Surface. Surf#1, is reasonable, but has broken down at point C .

Because Alias has to guess how the surface internals should be & base this solely on the shape of the boundary crvs, the surface internals have collapsed at point A & B

Note that the x-secs at the front and back of the surf are showing that near to the boundary crvs the surf internals are well formed

CV Hulls Tell the Story

just a quick look at the CV Hulls is all that is needed to see that this not anywhere near being a Class A Surf, in fact it is not even a concept surface. This is a typical 1st year students attempt at building a complicated Nurbs surface. It is what I call a failed srf.

the surf deg. is 5,5,1,1. and along its long boundaries it simply hasn’t enough CVs. to maintain its internal smoothness

the hood is 5,5,1,1. so we don’t want to change the degree on the other surfaces in the surf-set, as Class A requires that CV Hulls line-up where possible

Here in stark comparison is A Class A version of the same A5 shoulder area created by a pro. modeler. We can easily see the great skill level employed to align all the CV hulls so beautifully

Understanding the Language of Diagnostics

it’s easy to see by looking at the sharp peaks within the small surf and the 2 rounded shapes in the middle of the large fender surf, that these surfaces have failed internally

Getting Smooth Surface Internals

I have used remodelled x-secs taken from the 1st surf_set to build this set of 8 surfs (all deg: 5,5,1,1.)

We can see that all the surf boundaries are smooth, both on the large and small surf. This surface set has good internal structure and the highlights will be good

The x-sec at the front shows that this area is also good and note how smoothly all the tansverse fender crvs flow into the short crvs of the hood detail

These surfaces which I couldn’t have made unless I constructed  the simpler surf_set first, are now Class A.

What Do The Zebras Say?

By looking at the surfs in F5 we see that there is a beautiful flow of the Zebra Stripes indicating good quality surface internals

Also there is no sharp break, as the Zebras flow from the fender top into the hood detail surf. There’s just a smooth unbroken flow and we cant tell where the large surf ends and the small one starts. This is Class A.

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 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.
