Overview
CATIA Imagine and Shape is used in product conception stage. The basic principlebehind this workbench is to start with a very simple shape, a closed or a planar one andreach the idea you have in mind by manipulating and refining the mesh of this shape(rotation, translation, scaling, subdivision). You can also use GS1/GSD operators tocombine the surfaces and finalize the shape.
Surfaces created in Imagine and shape workbench are based on Subdivision Surfacetheory.

Introduction to Subdivision Surfaces
Catmull-Clark subdivision surface
Doo-Sabin subdivision surface
Origin of subdivision surfaces goes back to 1978 when Catmull and Clark, and Dooand Sabin first proposed to generalize bi-cubic and bi-quadratic patches methods tomeshes of arbitrary topology.

What is a Subdivision Surface
Subdivision algorithms are exceptionally simple, work for arbitrary control meshes andproduce globally smooth surfaces. Special choices of subdivision rules allow for theintroduction of features into a surface in a simple way.
Subdivision-based representations of complex geometry can be manipulated andrendered very efficiently, which makes subdivision a highly suitable tool for interactive
animation and modeling systems.
Subdivision is an algorithmic technique to generate a smooth surface as a sequenceof successively refined polyhedral meshes.

Subdivision Surfaces in Imagine & Shape
Control Mesh
4 sides face of the mesh
The subdivision surfaces in CATIA V5IMA are exact surfaces (Bezier orNURBS and not a polygonalapproximation) computed to reach anaesthetical shape.
A subdivision surface can be seen as askin made of elementary surface, it canbe close or open.
The topology of the shape is arbitrary,it enables then the description of alarge variety of complex topologies.
The definition and the control of theshape is made using a mesh. Thismesh is made of 4-sides faces.
Some mesh attributes can be added tocontrol the local attraction of thesurface and so obtain sharp or smoothedges in a single surfaces.

The contextual display can be turned on andoff using this icon.Three levels are available:
First level: no display Second level: Manipulation/Translation Third level: display all information
ToolbarsAll the functions have associated anddedicated toolbars to access options.No dialog panels are then displayed, savingscreen spaces.
Option keysThe shift and control keys are intensivelyuseable to manage selection and actionsThe contextual help give you a clear messageon the active keys and their actions.
Remote controlThe mouse cursor has not to be onto anelement or very close to interact.This gives you a real productivity gain and avery fast interaction with elements andhandles.

A powerful curve modeler based on an aesthetical approach supports thesubdivision surfaces technology
This new modeler provides users with a natural and intuitive way of drawingand controlling a complex curve
These curves can be created, a posteriori, in the model
The subdivision surfaces can be then controlled by curves for globaldeformation
The connections between curves are G3.

How to Create a Curve
Curve sketching
Created Curve
Use the dedicated Sketch Curve icon to create a newcurve.
A tools palette is displayed allowing you to specify adrawing plane. Use Plane Selection icon and select
an existing plane if you want to create a curve lying to.
If you dont specify any plane, the curve will be createdonto the view plane.
To create a curve, use the mouse to sketch or use apen palette if you can (better feeling).
Click and keep pressed the left mouse button, describeyour sketch and release the mouse button. During themouse manipulation, a graphic display shows you atemporary curve, this curve will be smoothed to createthe final one at the mouse release
As soon as you release the mouse button, the curve is
created.
The tools palette contains then additional options (seeCurve Manipulation section)
You can then continue to sketch to refine the curve

Use one of the two dedicated icons to create a first surface.
Open surfacesClosed surfaces
Surfaces are created using the current viewpoint information:It can be at the center of the screen or at the origin of thepart, depending on the CATIA settings.
View Centered: Creates surface at the center of screen Origin Centered: Creates surface at the origin of the
part
The size is a ratio of the window size (independent of thezoom factor)
The size of the mesh is equal to of the screen size Ex: if you have a 16 screen the size of the mesh is 4 Note: to manage accurately the size of the surface refer
to Scaling section
The model axis orientation is used to define the surfaces.The mesh is aligned along the model axis.
Open surfaces are created onto the plane which is the mostparallel to the screen.

The handle origin is by default positioned at the middle pointof the selected elements. To specify an other location use theCompass Definition option if needed.
During the manipulation, the surface is roughly pre-visualized.
The impacted area is displayed in orange color.
The surface is exactly computed at mouse release.

General Methodology (3/7)
Create your model by using several Subdivision surfaces. Avoid as much aspossible to create a complex shape with only one surface.
Try to think how to decompose the shape into elementary blocs, and also usingsharp edges. This is the key to speed-up the creation. See corresponding (General
Methodology 4/6 , 5/6 and 6/6).
Keep the Subdivisions as light as possible by limiting the mesh density, this ensurea better surface quality and an easy interaction with.
Combine the subdivision surfaces with GSD operations or other (trim, split, fillet) tofinalize the shapes.
Take benefit of Sharp Edges modeling. This gives a better feeling of the shape. Thesharp edges are then similar to styling curves. Use then GSD fillets onto thoseedges.

The mesh structure, so the Topology, has to be carefully managed, this is the keyto obtain the targeted shape.Before starting to create a shape, it is recommended to analyze the topologystructure of the shape you have in mind.Start then by creating a very light mesh structure corresponding to this shape, by
refining this mesh you will progressively get the final shape.A good way is to determine virtual sharp edges (filleted afterward with GSD), thisis very useful.

Collinear tangencies
Rules to apply in order to improve surface quality and insure offset computation
Subdivide sharp edges faces having collinear tangency corners propagating the subdivision to thecontinuous faces (multi-selection)
In some cases and in order to simplify the mesh, delete unnecessary faces at the boundaries (seenext slide)

Quality management 3/4
Valence 2
Valence 3(internal)
Valence 4
Valence 5
Valence 6
Valence 3(border)
The Valence of a vertex corresponds to the number of connected edgesExample:
If Valence = 4 internal or 2 border or 3 border surface quality = C2If Valence is different: the quality can be less (C1) but the surface can still be offset.

Quality management 4/4
Point located in highcurvature area
Point located in lowcurvature area
ExampleThe general idea is to move the particular valence points out of high curvature acceleration area
In a valence 5 case, very often managed in shapes, the shape located aroundthe valence 5 vertices is not very good.To improve this, subdivide the shape as illustrated and refine the mesh to geta similar shape. The surface quality is then better

Methods to Obtain Nice Shapes
To obtain nice shape curvature, try as much as possible to get an homogeneouspoints distribution.
The first illustration shows a good mesh distribution, the shape is very smooth.
The second illustration shows a non homogeneous mesh distribution, the shape iswavy.
