Evaluating what you have created in Alias is a real must have skill and you can learn it by following my Professional Training video course. I teach all the most tricky blends including the fully blended C Pillar found on German prestige cars.

Visual Clipping

The red comb is produced by the Dynamic Section Control “Visual Clipping Mode”

We can see that the transitional surface does not have a smooth xsec it has a flat in it.

Iso Shader

I have used this tool with “Visual Curves” to show exactly how the highlights would look on this surface. We can see that there is  a wave in the transitional surface set and just below the 3rd “W” there is a peak, caused by a curve which is too flat

Also just above the “i” the comb is showing us that there is no continuity between the 2 srfs.

 

 Visual Clipping in Alias

Towards the bottom. the blend only has G2 crvtr. but all 3 srfs. have a smooth xsec

At the top, 2 surfaces that should have G3 only have Tangency

So we can read a lot about the relationship between surfaces in Alias from these superb evaluation tools

A Pillar Blend

 Here-s a nice blend from a very good post grad, but is it professional?

No! Sadly it wouldn’t cut-it in Industry, because although the blend from A Pillar to Shoulder is very smooth, if you look carefully at the highlights, you will notice that the Visual Curves show the blend to be hooking in where the glass starts and it can never be made to align with the Sideglass Blend.

Building a Class A Blend from Side Glass (theoretical surface) to Shoulder surface

A lot of students find building perfect blends very difficult, so I would like to address this today. I tend to use square srfs. for this type of chain blend. The FFB tool is very powerful, but it is rarely capable of building a complex blend, which has to meet Class A spec.

The following video explains how to build bettter blends

Enjoy
