3 Rules for Creating a Typical Design Solution Assembly

3.1 General Rules Consult the Main Module of this AM.

Never add or delete geometry from a read-only assembly.

Do not work on an assembly, then reset the check-out in the vault and replace the assembly with its old version.

Never use Cut in preference to Delete. Do not cut a component from an assembly. Use copy and paste, and then delete the original component.

3.2 Naming and Numbering Consult the Main Module of this AM.

The file name (L53S1234500000.CATProduct) must always correspond to the assembly reference (Part Number = L53S1234500000).

− Change the Part Number field immediately (Contextual menu + Properties + Product tab) when a new CATProduct (File + New + Product) is created. Then save the file (Save As): the file name is then initialised with the assembly reference.

− The "Tools + Options + Infrastructure + Product Structure + Part Number + Manual

input" option must be activated when a new CATProduct is created in the Assembly Design Workbench with the New Product command. This option ensures that the Part Number field is filled in before the CATProduct is inserted. The file can then be saved with the "File + Save As" command.

Remark: The "Save As" command must be used after any change made to the Part

Number property to ensure that the file name corresponds.

3.3 Standard Parts Standard parts are elements defined by a standard document.

All standard parts should be shown within the DMU with the exception of fasteners, which should only be used in the following conditions:

− Proof of design − Clash or clearance condition − Specific DMU requirement − Supportability study − Installation assemblies

Fasteners created with automated assembly techniques should not be included in assemblies and represented as a point and vector.

Standard parts are delivered through the CADLIB in a CATIA V5 catalog named "StandardParts.catalog". The classification is delivering by ESW and is the same than the ESDB one.

The structure of this catalog is as follow.

3.3.1.3 Search a Standard in the CATIA V5 Catalog Browser

It is possible to search a Standard in the CATIA V5 catalog browser and to open automatically ESDB at the same position:

− Open the CATIA V5 Catalog browser, at the desired Standard or Standard Part.

Result in the CATIA V5 Catalog browser

− Open ESDB and type the following URL in your web browser (set it as a favorite after the first use): http://esdbexp2.eu.airbus.corp:1083/WT62ESDB/ext/esdb/jsp/cadlib/cadlib.jsp?action=GETSTDPROP

For subcontractors using ESDB outside of AIRBUS, ask to your support focal to know this address

− In ESDB, you will find the result page for the desired Standard or Standard Part:

3.3.2 Tree Organisation It's possible to organise the assembly tree by adding some nodes to group under the same standard parts type. The procedure is:

1. select the product (e.g. named L1234567800000),

2. add a "Component" (e.g. named L1234567800000-STD02, L1234567800000-STD03…),

3. add under this component all standard parts of same or different standards.

Components are not mandatory.

3.3.3 Rigid Parts These types of elements are inserted in the 3D environment with the same shape they have inside the library (e.g. Screw, bolts, nuts…).

To insert this type of element in a product: − search the desired component in the catalog, − instantiate it and keep the link with the component in the catalog, this means that you

don't use the option (in the contextual menu) "Instantiate as new component…", − place the component in the environment as a classic part.

This type of standard part shall not be saved, when the CATProduct is saved, only the link and the positioning of the element contained in the catalog is saved.

3.3.4 Flexible or Movable Standard Parts These types of elements are inserted in the 3D environment with a specific shape:

− In other terms, these standard parts have a certain shape with a reference (Part Number) in the catalog and are deformed when installed on the aircraft, i.e. inserted in their environment in the mock-up.

− Standard elements, which parts inside, have a given position and a different one when installed inside the aircraft, i.e. inserted in their environment in the mock-up.

The solution in all cases is to rename all deformed and mobile parts, which have components with new positions with regard to the initial product in accordance with the AP2610 or AM2215.

The parts are then duplicated in the CATProduct with a new reference and the original in the catalog remains intact.

Please note that each deformed part must have a reference. Never place all of these parts in a single CATPart-FLX01.

CAUTION: Do not use the "Flexible/Rigid Sub Assembly" command in the Assembly Design workshop as this causes problems when assembly trees created with CATIA V5 are converted to Product structure format.

3.3.4.1 Flexible Standard Parts

Create in the L5312345600000 assembly, a L5312345600000-FLX01 location node (CATIA V5 Component) to group inside the same type of components. For another type of components, create a L5312345600000-FLX02, L5312345600000-FLX03, …

Search in the CATIA V5 catalog the desired component and in the contextual menu, select "Instantiate as new component…".

Modify the "Part Number" property of the standard element inserted.

e.g. L5312345600000-FLX01 if this element must be inserted directly into the L5312345600000 assembly. But L5312345600000-FLX02 if this element is inserted under the component L5312345600000-FLX01, because it is impossible to have the same number (FLX01 for the component and for the CATpart).

AM5012 Module 1Issue : A

3.3.4.1.1 Flexible Standard Part with Movable Component

Example: Rod-end

Activate the CATPart and modify the position of the two bodies by rotations or translations ( ) to adapt their own positions to the environment.

Then save the L5312345600000-FLX01.CATPart part in the create directory.

Repeat these operations to insert the same standard part with another position in the same 000 assembly.

3.3.4.1.2 Flexible Standard Part with Flexible Elements Inside

Example: Bonding breads

Figure 6: Flexible part instantiation

With constraints or SNAP functions, place the CATPart (the body on the origin) in its environment.

3.4 Flexible Assembly Flexible assemblies are a similar problem as the flexible components. But flexible assemblies are dealing with different positions of the same parts and not with different geometrical derivates.

The following rules apply: − the content of a flexible Assembly is identical to the content of the reference

assembly, − only the most actual issue of the components (single parts) shall be used, − the single parts are released,

− flexible assemblies, where the position of the parts is the same, are identical (multi instance),

− the geometry of the parts shall not be altered, − the components of the assembly have own part names and they are managed in

separate parts, − only the position inside the Flexible Assembly shall be altered, − flexible assemblies are named according to the part name of the assembly they are

going to be built in (next assy). Additional to the partname, the flexible part gets an extended part code "-FLXnn", where "nn" is an counter between 01 and 99.

In the "Properties" panel of flexible CATProduct, write in the "Definition" field the Part Number of the original assembly (often the norm name of the Component or Equipment number).

E.g. Original assembly part name: L5212345600000

This assembly is used in a Design Solution but elements inside have a different position. The Part Number of the DS is L5212345600000.

The properties panel of the assembly is:

4 Design in Context In order to fully use the functionality and associativity of CATIA V5, design in context, and maintain a clean Digital Mock-Up (DMU), the Design Tree methodology has been defined for use during the Definition and Development Phase. In certain circumstances during the Definition Phase, an integrated ENV methodology can be used. This is outlined in section 4.2 and is only to be used with prior agreement from the Zone Integration Team.

4.1 Definition and Development Phase

4.1.1 Design Tree Methodology The design tree is used to manage an environment for design in context for parts or assemblies.

Main components of the design tree are: NAME

4.1.1.2 Rules for the Design Tree − Geometrical environment data shall only be linked to the environment node. − The environment node shall be data of CATIA V5 type "Component" to avoid having

multiple files with environment data stored to file systems. − Changes made to an assembly or a part shall be performed in the design tree

containing the respective environment. − Never use Cut in preference to Copy + Delete. − The design tree should also be used for drawing creation. For more information refer

to the drafting methods: AM2264

4.1.2 Creating and Updating the Environment An environment node is necessary to manage needed geometrical environment data. In the following, you will find information on how to link your geometrical environment to the environment node.

4.1.2.1 Rules for the Environment

It is essential to use validated data in the environment in order to work efficiently and coherently in Concurrent Engineering. Regularly ensure that it contains the DMU technical solutions.

When linking geometrical environments to the environment node, it is necessary to keep the positioning from the originating assembly.

To assure this, link operations are divided into two methods, according to their position inside of the product structure:

− Method One: No positioning. Relative co-ordinate is 0, 0, 0 − Method Two: Assembly or Parts are already positioned

Please note, that there may be a positioning matrix for each LO (Linked Object) between CI and DS level.

4.1.2.2 Method One: No Positioning

There are no position matrices to be retrieved when the assembly to be inserted is at the first level of the technical solution. The "Existing component" command can therefore be used, and CATProducts in the corresponding READ directory can be selected.

NO.

TASK GRAPHIC

1 Open your design tree in CATIA, using file → open from the main menu.

2 Select the "ENV" node. 3 Indicate on the "ENV" node and select

"Component" from the contextual menu.

4 Select "Existing Component" from the

Component sub-menu. Alternatively: • select the "Existing Component" Icon

from the "Product Structure Tools" Toolbar,

• select the "ENV" node.

4.2 Definition Phase Using an Integrated ENV Node This is an alternative method, where links and constraints are required with Master Geometry.

Typical uses of this method are with the Tubing, Electrical and Kinematic workbenches.

As mentioned previously, this method should only be used with prior agreement from the Zone Integration Team.

4.2.1 Create a Design Tree Assembly (CATProduct) The Design Tree Assembly contains the working environment for the designer. It holds all the necessary external reference geometry required to design parts and sub-assemblies. The Design Tree Assembly is the first nine digits of the Design Solution Assembly.

1. Create a new assembly (File + New Product): T57P56068 2. Add a description to the assembly (MB3 (Mouse Button 3) + Product + Properties -

Description): Description: DESIGN TREE

4.2.2 Create a ZONE Component Parts or assemblies used as reference geometry are grouped within a Component called ZONE. Components are internal sub-assemblies within a product structure and are not saved as external CATProduct files.

Create a Zone Component as defined below:

1. MB3 (Mouse Button 3) (MOUSE BUTTON 3) over the Design Tree Assembly and select Components + New Component.

2. Enter the name ZONE in the corresponding window.

3. Fix the ZONE Component.

4.2.5 Create an Environment (ENV) Component Normally all reference geometry is placed in the Zone Component, however during the Definition Phase where geometry parts have a tendency to change, a link may be required to capture any modifications. Hence, Master Geometry Parts, where published elements and multi-model links are maintained, are grouped in a component called ENV.

Please Note - Components are internal sub-assemblies within a product structure and are not saved as external CATProduct files.

Create an Environment Component as defined below:

1. MB3 (Mouse Button 3) (MOUSE BUTTON 3) over the Design Solution Assembly and select Components + New Component.

2. Enter the name ENV in the corresponding window - Fix it.

4.2.5.1 Add Existing Components to the Environment Component

4.2.5.3 Add Existing Components to the Design Solution Assembly

The first part added to an assembly is termed the primary part. The primary part is fixed in place. All other assembly (secondary) components in the same design solution assembly are then constrained to it. In normal circumstances, the primary component can be described as follows:

− a part with a local axis system defined in the Local Axis Datum CATPart, − the major component that all peripheral components are designed about.

All assemblies require a fixed primary part otherwise all parts within the assembly will be free to move without constraint. Assemblies can have more than one fixed Primary Part.

1. Use Open in New Window to change to the Design Solution Assembly Window.

2. For the purpose of this exercise, the first spoiler part has already been modelled. Add the Spoiler1 Hinge3 part to the design solution assembly.

T57P56088200000.CATPart If an existing part, such as the spoiler, is added to the assembly it positions itself about the origin of the Product and not its correct orientation in space. Therefore any parts added to the assembly require correct positioning in model space.

4.2.5.4 Positioning a Part with a Datum Axis

Parts are created about a local axis system, which means that their parent assembly controls their positional matrix (orientation) within the Digital Mock-Up (DMU). If an existing part were added to the assembly it would position itself about the origin of the Product and not its correct orientation in space.

Parts designed within CATIA V5 have an axis system created at the part origin. This can be found in the Specification Tree under Axis Systems. The procedure for moving an Axis System (origin) of a part to its correct Local Axis Datum position in the design solution assembly is defined as follows:

Use the following procedure to snap the Spoiler1 Hinge3 part to its correct axis location in the master geometry datums part.

1. Change window to the Design Tree Assembly.

2. Ensure that the Design Solution Assembly is Active.

3. Select the Snap Icon.

4.2.5.6 Deactivating the Environment

It is important not to replicate the reference geometry within the Environment component across the DMU. This is achieved through deactivating the Environment node, which in turn deactivates all reference geometry within it. The environment node should be deactivated prior to any assembly being vaulted.

The procedure for deactivating an Environment Component is defined as follows:

1. MB3 (Mouse Button 3) over the ENV Component and select:

Env1.Object + Activate/Deactivate Component. 2. The environment node can be activated with the same procedure.

6 Mirrored Parts within Assemblies For the description and definition of Mirrored Parts and Assemblies, see the main module of this document. To mirror an assembly and all associated parts, a Design Tree is required to maintain all links with the "As Drawn" Design Solution. If a Design Tree already exists for the "As Drawn" assembly, use this to create the RH assembly. Method

− Create a new Design Tree CATProduct M53S20035 − Add an ENV (or ZONE) component to contain the co-ordinate axis system − Add the Left Hand CATProduct M53S2003500000

Figure 16: Mirrored part or assembly method

Important: To maintain all contextual links, ensure the CATProduct chosen for symmetry is loaded in Design mode.

− Select the "Symmetry" icon − Select the symmetry plane > Finish

Please Note: Co-ordinate systems (0, 0, 0) matrix) will be defined and distributed to each Major Component and used as reference in the design and for the exchange of information (ref. AP2266). These reference axes will be used to define the symmetry plane for all opposite hand assemblies and its components.

If a CATPart must be mirrored alone, it has to be mirrored at part level.

Refer to AM2259 - 3D Modelling Rules for CATIA V5.

RECOMMENDATION A-UK only Due to the functionality of CATIA V5 and the wing axis system deployed by Master Geometry, it is recommended that the "Symmetry" command is NOT used. All Opposite Hand geometry is to be mirrored at part level and positioned manually in the Right Hand assemblies.

7 Designing a New Technical Solution from an Existing One The need is to duplicate an existing technical solution by giving new references to the

elements composing it to obtain a separate CATProduct.

Remark: The same method is used whether or not the technical solution contains a contextual

part.

STEP

ACTION/ILLUSTRATION

1 Modifying Part Numbers All components contained in the root CATProduct are listed in the "Product Management" window: Tools + Product Management (Assembly Design workbench command).

Modify the Part Numbers of all components to be duplicated

8 Checks to be Performed Before Storing See the Main Module of this document.

8.1 Unique Universal Identifier (UUID) A UUID is a unique number recorded inside all CATIA documents. When CATIA opens a document (such as a sub-assembly) its UUID is checked. If the UUID differs from the original number, the document will not open correctly and cannot be vaulted. This can be caused if the original sub-assembly is deleted and restarted, changing its UUID number. Note: All CATIA documents, which have a UUID that is different from the originally vaulted

document, will be rejected by the PRIMES PDM system.

8.2 Avoiding UUID Errors

8.2.1 Basic Rules UUID errors can be avoided by following a number of basic rules:

− Always preserve the original vaulted CATIA document. − Never overwrite CATIA documents with new versions using UNIX or Windows. − Never delete and restart an existing CATIA document with File + New, File + New

From or File + Save as New Document.

Only modify existing CATIA documents with the following methods: − Use File + Save Management/Save As to renumber existing parts, assemblies and

drawings. • Keeps the same UUID number. • Maintains drawing links.

− Only use File + New From to create a new part derived from an existing part.

• Used for new part numbers. • Creates a new UUID number. • Links to existing drawings are not required.

8.2.2 CATProducts The designer must always maintain the original CATProducts. Do not replace with new versions, which will cause UUID errors. The supplier must always maintain the native CATProduct delivered as part of a work package from Airbus. Once a new CATProduct has been delivered to Airbus, it must be maintained in its original state. This rule applies to all CATProducts, which are returned to Airbus or vaulted in a modified state.

8.2.3 CATParts The designer must always maintain original CATParts. They must never be overwritten by new versions, which will cause UUID errors. When new revisions of parts are generated through automated processes, it is recommended that the new geometry pasted into the original CATPart. This rule applies to all CATParts, which are returned to Airbus or vaulted in a modified state.

8.2.4 CATDrawings The designer must always provide drawings with view and object links intact.

8.3 Maintaining a Correct Product Structure

8.3.1 Basic Rules A CATIA V5 CATProduct records all the links on sub-assemblies and parts within its product structure. In order for "CATIA" to open any assembly correctly, these links need to be synchronised each time the assembly is loaded.

There are some basic rules that enforce synchronisation and minimize errors: − Parts or products must only be added or deleted from a sub-assembly when it is open

in its own window (at root level). − Assemblies and parts should not be open in "CATIA" when storing to the vault. − Always replace parts with Replace Component.

8.3.2 Broken Links Broken links are created when CATIA cannot find a specific part or assembly inside a CATProduct, either because that component cannot be found or it contains an incorrect UUID number.

Note: CATParts with UUID errors can be visualised, but cannot be loaded into design mode. Support should be contacted if this error is encountered.

Note: All CATIA documents, which have broken links to parts or products not already in the vault, will be rejected by the PRIMES PDM system.

8.3.3 Ghost Links Ghost links are incorrect duplicate instances of parts or products that are visible within in the product structure. Ghost links can be avoided by adhering to the following rules:

− When working in an assembly with sub-assemblies, all affected CATProducts must be vaulted in the same working session and not at different times. This ensures that all links are synchronised.

− Never attempt to add or delete geometry from a read-only assembly. − Do not work on an assembly, delete it, and then replace it with an older version. − Never use Cut in preference to Delete. Do not cut a component from an assembly:

use copy and paste, and then delete the original.
