Patch Layout Audi A5 Sportback

This is the teaching model I use with my students. I use the A5 because it is a very demanding to construct.

The surfaces are very subtle and unless you plan your patch layout very carefully the model will fail

I have built the entire center of the car with apexless surfs. When building these I select symmetrically oposite CV’s and digitally align them in the Info. Window.

The Hood and Grille are made from two deg 5,5,1,1. surfs

Screen and roof are resolved with a Surf. Fillet G2 and then by pulling Cv hulls within the blend (3rd row) G3 is attained

The A5 Cant Rail has 2 surfaces (surf.#1  &  2)

Patch boundaries on the Body Side are designed to Align with Patch boundaries on the Shoulder (see Patch Align)

REF: Patch Layout for Body Side is modelled with curves and then Imported and made Inactive

The Side glass is modelled flush with the sheet metal and a lot of time is spent aligning it with the aperture in both TOP & SIDE

We call it the Side Glass, but actually this is a Misnomer. At this stage it just representing the sheet metal Level. It does not have exactly the same shape as the real Side Glass

Patch_Layout_Shldr-BSide-1

Side Glass is Ultimately Moved Inwards by 22 mm

Later on in the model when the “C” Pillar has been modelled the side glass will be moved inwards to it’s correct position.

At this point it will have to be hand modelled, as the sheet metal had to curve in to wash out into the “C” Pillar. Now it can be trued up again

to restore the highlights

SideGlass_moved_in_1

NB: This patch layout is only an example and is NOT the layout that I personally use.

Dynamic Section Control – Alias

Dynamic Section Control – Alias Surface Studio

6

The above model is looking rather nice for a Concept model,

but there are some big surface issues that need to be put right

1

Dynamic Section Control – Alias Surface

Using this tool with Visual Clipping checked, it’s easy to see that my nice concept model has some major surface continuity problems, which MUST be put right

because I didn’t check the angle of the bumper surf (corner)  earlier I didn’t spot the twist in the bumper

I then went on to build the apron to an incorrect surface boundary resulting in the big inflexion that can clearly be seen here

NB: This tool will create a construction plane for any cross section that you demand and this I’ll use to view the section in True View

2

I’m taking a look from another angle here to see the extent of the problem

“A” the bumper angle is cutting back too much

“B” because the top of the apron is built to the bumper it has created an inflexion

3

A = end of spoiler

B = bumper

C= Inflexion

4

Here I’m looking at the x-sect in True View

and using the combs to show where all the surfacing issues are

$= Combs/Quills cross showing the inflexion

A= Inflexion in the Bumper’s top surf

B= Bumper angle incorrect

C= Inflexion between Apron and Bumper vert. surf

6

The Big Fix!

Here I have

  • Isolated the section
  • Changed my working x-sect crvs to deg. 5,.1.
  • Aligned all the crvs
  • corrected the top bumper inflexion
  • Moved the intersection point of Bumper & Apron out to eradicate the inflexion
  • Created<curvature conditions for the apron crvs

Now I can rebuild the bumper and Apron using the above X-Sext crvs.

Autodesk Alias – Rear Number Plate Depression

How to Approach Building a Number plate Depression

A lot of students get stuck trying to work out how to go about modelling the rear number plate depression, so I’m going to show you how I go about this

fig.1

1

Create this surface (A),

but don’t think about the depression initially, just concentrate on building a really nice surf

I built this surf across the XZ plane as an Apexless surf and then trimmed it on the XZ intersection

fig. 2

2

Rear View: Project to establish these COS.

We are going to trim the outer flange of the number plate depression from the rear panel . As this car has a hatch back it has a parting line “B”, which is a convenient place to divide the panel we want to detail from the rear end. If you don’t have a parting line on your model, then you only need to create the inner COS. You can trim divide the enclosed surface, as I have shown in fig. 4.

fig. 3

3

Before I trimmed the number plate area out,

I created  the Bumper to Rear Panel blend “A”

Thhis trim edge is where  I will build the depression surfs. from “B”

Surf. “C” is a simple Drafty Surf.

fig.  4

4

You will end up with the surrounding flange

and then you will need to create a surface for the actual number plate to sit on

Once you have the numberplate mounting surf. built and located

Start running deg. 3 , 1. curvs. from the number plate surf to the flange and then build Square or BiRail surfs to form the sides of the depression

Use the Surface Fillet Control to soften the corners.

fig. 4A
7

This is from an Audi andthe depression is rather complicated requiring extra surfs.

Most times I only need to create 5 surfs plus blends

fig.  5

5

fig.  6

6

I hope that I have shown how, what appears to be a complicated task can be made easier by isolating the area you need to develop within your model.

Alias Tutorial – Surface Fillets – Variable Radius

100% of donations go to provide food shelter and education for the abandoned Street Children of Nepal. Please give a few USD/Euro back. Why not do it right now by C.C. or Paypal? Charity credetials: BUDDHA MEMORIAL CHILDREN’S HOME TRUST. Registered Charity No: 1115373 . Thank you, graham bullock

Variable  Radius  Fillets

There are many occasions when the Designer will require you to build variable radius fillets

This detail is a Halogen lamp housing which is blended into a complex curved surf, that moulds around the

corner of the yacht. The Stylist requires it to have a large blend of 100.0 on the outside, but a much smaller 20.0 mm blend on the inside

2

Start by making a complex curved back plate

Front: make 2 crvs that represent the outer wall and 2 circles that represent the wall of the lamp

Now project them onto the back plate and hide the original curves

3

Draft /Flange Surf Option

Select all the COS , then set depth and pull direction. I am pulling on the Y axis

4

Once you have created the draft surfs.

put a skin surf across them to close them off and then

using the Round tool, select all the edges and fillet them all in one go

5

6

You should have a basic back plate assy that looks like this (above)

7

Trim away the flash

and put the outer wall on a new layer. Make it inactive

8

Set the Surface Fillet Control as shown above

(I have used a default tangent offset value of 20 but you may probably need the std.default setting which is 10.0000)

  1. select the back plate it will turn pink, then hit accept
  2. select the outer wall it will turn yellow then hit accept
  3. now you will see a yellow and a pink arrow. these indicated which side of your target surfs the fillet will build, if they are not pointing the right way, just click on the incorrect arrow to flip its direction
  4. now hit “build”

9

now you will see that a uniform radius fillet has built

  1. click on the right hand side of the  blue indicator line
  2. a radius indicator will appear. In the prompt line, type in a high value , mine was 100. you may onlyneed say 25 to 50
  3. click on the leftt hand side of the  blue indicator line
  4. a radius indicator will appear. In the prompt line, type in a low value , mine was 20. you may need less
  5. hit Recalculate and the final variable fillet will build

12

Curvature Evaluation

set to “mean” and value 10.0 we can see the superb quality of surfaces available from the Surf Fillet Control

13

Zebra Stripe Diagnostic

tessellator turned up full, plot set wide and Shader Anti-Alias set to medium, everything looks fine

10

the Stylist is right again the variable radius fillet looks beautiful

Dynamic Modeling  with the Conform Rig Tool

A very talented student of mine modelled this Harley tank and I wanted to show him ways of developing his model by adding a rubber knee pad and a filler capa lot of the time I model these things in situe. I start by projecting crvs to get a COS and then I model say the knee pad. The problem with this approach is that it’s not flexible and when the designer requests a change , it may call for a lot of re-modelling.

The Conform Rig Tool is the answer in a lot of cases, as it allows you to move and scale your geo, whilst the new geo. continually adopts the shape of the immediate surface on which it has been placedAbove you can see where I have created the new geo. at the origin in the Top view and then transplanted it to conform to the tank’s side surfs.
