2 NOMENCLATUR E Nomenclature for files making up the assembly, (CATPart, CATProduct, V4 Models) is defined in the procedure AP2610 Naming and numbering for new projects. Nomenclature to be used on the different elements generated during the assembly activities (Scenes, Interferences, Constraints, etc.), will be the default naming and numbering given by the system.
3 STRUCTURE OF THE SPECIFICATIONS TREE The specifications tree is split into four main parts: • • • •
Parts group: Parts grouping Subassemblies group: Subassemblies grouping Constraints Node: Node containing the different relationships between parts made with constraint elements Applications Node: Node containing the applications carried out in the CATProduct, (e.g. Calculation of interferences, Scenes, Hyperlinks, etc.)
The sequence of these parts in the specifications tree is shown in the image below:

3.2 Applications nod e The applications node is the node grouping all t he applications carried out in the CATProduct within the structure of the specifications tree, (e.g. Calculation of interferences, Scenes, Hyperlinks, etc.) This nodes is created automatically whenever any of the DMU activities is performed, and after created, any new application carried out shall be included, also automatically, in this node.

The other procedure to insert elements into an assembly is inserting an existing component. This component should be available in the Modlocal, because a Get or a Read from the VAULT has alreadybeen performed on this component. Follow the steps below to include it: •
Select the Insert+Existing Component option, the window to insert an existing element opens
•
Search for the element to be inserted by means of a String search in the Modlocal directory
•
Select the component to be inserted and click on the OK button. Component to be inserted

5.2 Multi-level assem bly A multi-level assembly includes part components as well as subassemblies. The following is the component insertion process in a multi-level assembly, distinguishing part components insertion from assemblies insertion
5.2.1 Part components insertion The same process as that used for single level assemblies shall be followed for the insertion of part elements: • • • •
Sign out Open the work assembly Open the element to be inserted Split the screen into two windows

5.2.2 Subassemblies insertion Two types of subassemblies are distinguished when they are to be inserted, small assemblies and large assemblies. Small assemblies insertion shall be made by visualisation thereof and large assemblies insertion shall be made without visualisation. The following is the assembly insertion process without visualisation •
Open the work CATProduct without visualisation
To open a CATProduct without visualisation, Options is selected from the Tools menu. Select Product+Product Structure, from the window opening up and select option: Do not activate default shapes on open as shown in image below:

Sign out assembly in Vault Open it from the Modlocal Perform a Read Latest Rev on the V4 element to be included Insert V4 element as an existing component from the Modlocal directory Replace assembly in the Vault
Processes stated in above paragraphs shall be used to include V5 elements into the same assembly, either for parts or subassemblies.
5.4 Assembly comm on to different departments When it is necessary to create an assembly including subassemblies from different departments to perform a clash detection, or to perform different mock-up activities, the process stated in Multi-level assembly shall be adhered to.

7.2 Standard parts p ositioning Standard parts positioning depends on supporting geometry on which they are to be located. The following classification has been established based on the support.
• • •
Along a direction. Supporting on flat surfaces. Supported on surfaces
Positioning of repeated standard parts along a direction. The following is the process to be followed: • • • •
• •
• •
Locate the standard part in the tree in the traditional manner. It therefore stays in its 0,0,0 position. Approach it to the support by means of the snap option, selecting any point in the standard part and any other point in the support. Position it in its final position using snap, constrains or compass. Select option fast multinstantiation definition and the following window opens up:
Select the standard part as element to instantiate. Select the type of parameters desired to provide, the number of standard parts, spacing between each other or total spacing between the first and the last ones in the parameters tab (two out of the three ones have to be selected). Enter the values of the selected parameters. Enter direction in which parameters are located. It may be an edge, a flat surface, etc.

Multinstantiation Direction First standard part positioning
Standard parts positioned according to a direction
Positioning of standard parts supported on flat surfaces.
Dealing with flat surfaces, there are two positioning alternatives, depending on whether patterns exist or not. Process is as follows if there are preset patterns: •
Position the first standard part in the same manner as in the above paragraph (snap, constrains or compass) located in the feature (hole) origin for the pattern. (It is assumed a pattern has been created for each different type of standard part).

Should there be no patterns, standard parts are positioned one by one using constraints, snap or the compass
Standard parts positioning laying on surfaces.
First of all it is necessary to have the hole feature (in addition to the positioning point) created on the support in each location the standard part is to be positioned, in order to facilitate the process. The following is the process to be followed: •
After the standard part to be positioned is located in the tree structure, it is approached to the support by means of the snap function, selecting one point in the standard part and another one in the support.
•
Perform a multi-instantiation of as many repeated standard parts as necessary in any direction. Move to the coincidence option and select the hole centre line and the standard part centre line for each standard part and with the same option, select the standard part bearing surface and the support point. Repeat the process for each standard part.
•
•
Note: If the surface was ruled, there is the possibility to use the multi- instantiation if standard parts are located along one of the rules of t he surface.
