Selecting Elements

Vertex

Edge

Selecting Elements can be done in the geometry area or in the specification tree.

In the geometry area you normally select a sub element of the geometry. For a Solid the sub elements are:

• Vertex

• Edge

• Face

Geometry area

During a modification this sub elements will be new calculated by CATIA and in some cases the

references will be lost!

Face

When ever possible use the specification tree for select elements. Because, these kind of selection

is a more stable solution for modifications and updates!

Specification tree

In the specification tree you

can select only whole features.

Colours (1/3)

See AM2232 Module 1 Layers and Colours within CATIA V5

With colours a hole part or sub elements

of a part can be marked.

Colours can be defined for different elements:

CATPart

• Face (Solid)

• Feature

• Body

• Wireframe and Surface

Inside a CATPart the priority of the element colour is from bottom up which can be analyzed with the

graphic wizard (CATIA V5 R14):

Introduction

Colours (3/3)

Regulations for Colours

• Do not use the colours red and orange, because this are system

colours of CATIA V5 and define a special model status.

• Do not use colours on Product level

• A CATPart should have only one colour.

• For A-UK set all colourdefinitions back to colour by layer. (see NATCO

Add-on)

(33)

Introduction

Layer (1/2)

See AM2232 Module 1 Layers and colours within CATIA V5 See AM2232 Module 2 CAD Layers Organisation

CATIA V5 functionality enables

designers to manage their own design

and data organisation without layering

use.

Nevertheless, the use of layers is necessary for

Master Model identification, DMU Visualization, Data transfer and Manufacturing processes

CATPart

• In case of solid definition, only the Part-body has to be on a layer

• In case of wire-frame or surface definition (MG, DP, FM), the Open-body grouping

some elements might be on the appropriate layer and elements inside the

Open-body may be on layer none

• Use of layers forbidden for Part Number property level

CATProduct

Use of layers forbidden for CATProduct and CATPart Part Number property levels.

Introduction

Layer (2/2)

To change the layer of an object

• select the object

• select a layer in the Layer box

Catia V5 provides

several layers. All

layers will be visible

in the layer box

Note:

It is not allowed to modify or

• "None" in the Layer box indicates that there is no current layer for the

selected object.

• If an object is selected, the name of the layer on which the object is

located is displayed in the box. To find out which layer an object is

assigned to, select the object and look at the Layer box.

• When no objects are selected, the layer is displayed in the Layer box

as “None”

• Any new objects will be created on the current layer

• To move from the current layer, make sure that no object is selected,

then enter the new layer number in the box.

Select View > Toolbars > Graphic Properties

Sketcher

Basics

• A Sketch is a geometric elements which contains one or several

contour created in the Sketcher workbench.

• The sketcher workbench provides a set of functions for creating and

modifying sketched elements.

• A sketch contour may include profiles, construction lines and points

• It is possible to apply constraints to the sketched elements.

• In the Sketcher it is possible to work with an individual degree of

parameterisation. This is not allowed at AIRBUS.

(39)

Sketcher

Sketcher Rules

• Keep sketches as simple as possible to make modifications easily.

• Don’t create geometry which can be created as a feature

(e.g. fillets, chamfers, holes)

• Use the mirror function in the Part Design, not in the Sketcher.

• The sketch has to be fully constrained.

(40)

Sketcher

Sketcher Rules

Allowed Sketch Contours

Not Allowed Sketch Contours

One closed contour Several contours

Open contour

Sketch Contours with restrictions for some solid features

Intersecting open contour

Several contours

Intersecting closed contours Self intersecting contour

There are some restrictions for sketches to create solid features:

(41)

Sketcher

Accessing the Sketcher (1/4)

Note: If there is no CATPart open, Start > Mechanical Design > Sketcher will create a

new CATPart inside the Part Design Workbench

There are different possibilities to start the sketcher:

• Inside e.g. the Part Design or Wireframe and Surface Design Workbench click the

Sketcher Icons

Sketcher

Sketch with Absolute Axis definition

• From any Workbench double-click an existing sketch

(42)

To define the Sketch Support, select a plane or a planar face or surface (either in the

geometry area or in the specification tree).

Sketcher

Accessing the Sketcher (2/4)

Sketcher

The normal of the working support is the same as the principal normal of the selected plane.

Eg. If you choose a plane parallel to the xy plane, the principal normal is z. The origin of the

Absolute Axis system of the sketch is automatically positioned on the origin of the CATPart.

Sketcher

Note: A sketch used to create a Part Design element (e.g. a pad) should be created directly in

the body that will contain this element and not in an open body. Otherwise it will be duplicated

and its management will be trickier. (See AM2259)

Intersect 3D Elements

Scale a profile. The distance values will be resized, the angle values will not be modified. (Multi-)select the element to be scaled, define the centre point on the geometry, enter the scale value. The duplicate mode is activated by default. Internal constraints can be preserved. External geometrical constraints are killed. External dimensional constraints are modified.

Create an offset of 2D geometry (lines and curves). Create an associative offset of 3D geometry (edge, face and geometrical features). To modify the offset options (No Propagation, Tangent Propagation, Point

Propagation and Both Side Offset) use the Sketch tools toolbar. Constraints are not created. No propagation on 3D edges.

Intersect 3D elements (e.g. edges, faces, pads) onto the sketch plane. If you select a face or pad, the edges are projected. These projections (marks) are yellow and associative to the 3D part. If needed, use the contextual menu to isolate the marks.

Project silhouette edges from a canonical surface onto the sketch plane. The axis of the canonical surface must be parallel to the sketch plane. These projections (marks) are yellow and associative to the 3D part. If needed, use the contextual menu to isolate the marks.

Toolbar Sketch Tools

If activated, this option makes your sketch begin or end on the points of the grid. As you are sketching the points are snapped to the intersection points of the grid.

Create standard elements when the icon is inactivated and construction elements when the icon is activated. Construction elements are not taken into account when creating features, and they do not appear outside the Sketcher

Dimensional Constraints will automatically be created while creating the sketch.

Usual No 3D Background

Cut the 3D Solid geometry temporary on the sketch plane to see the inside the volume.

The No 3D Background mode hides all geometrical elements and features (products, parts, etc.) except for the current sketch.

Cut Part by Sketch plane

The Usual mode is the default option. When activated, the 3D geometry is visible in the Sketcher.

Low Light

In the Low Light mode all geometrical elements and features appear as gray-colored, except for the current sketch. You cannot select the 3D geometry, you can just handle Sketcher elements.

Geometrical Constraint

(74)

Constraints are used to control the size and the position of an element

and its relationship to other elements.

Geometric Constraints

control the

• relationship between the elements (e.g. coincidence, parallel) or

• the orientation of an element (e.g. horizontal, vertical).

Dimensional Constraints

control the

• size of an element (e.g. length, radius) or

• the distance and angle between elements

Green

Iso-constrained

The element is fixed and cannot be moved from its geometrical support. (E.g. if you fix a line it is still possible to move the endpoints)

Sketch can be used

White

Under-constrained

Still some degrees of freedom remaining Sketch can be used but is not allowed at AIRBUS

Purple

Over-constrained

Too many dimensions have been applied to

the geometry

Remove one or more dimensional constraints

Red

Inconsistent

The system is unable to find a consistent solution for the dimension system

At least one dimension value needs to be changed

Brown

Geometry

not changed

No recalculation because some geometrical elements are over-defined or inconsistent

Remove one or more constraints
