CATIA allows the user to perform design optimisation in a short time using “ product engineering optimiser” inside the “knowledgeware” module. CATIA Knowledgeware. CATIA® V5R Formulas. Formulas are used to build relationships between parameters. They are the first type of relation that you will. Catia V5 knowledgeware awareness session. Francois Trudel.

A visual indicator located at the relations set level indicates that the set contains hidden relations. In the specification tree, a broken or invalid design table is displayed. Specifying the Material parameter value. The value is the only information that is taken into account by formulas or rules.

The Value List window is displayed. You can also add a comment to a parameter to indicate the reason for the Knowledgeware control. If need be, rename this parameter. Parameters to be inserted can be multiselected. You can easily associate two parameters from a parameter editor.

Edit the parameter, then in the edition box, right-click the value field and select Add Range However, only the value of the object is propagated to subsequent steps. U3 has a range of acceptable values created using Add range ; there is no indication that this Knowledgeware technique is in use unless you enter a value that exceeds the allowable range.

This part is intended for those of you who need a quick answer to their questions about the Knowledgeware capabilities. Second Method Click the icon in the Knowledge tool bar.

You can type the filtering relation directly in the appropriate field or click Edit To reorder parameters, right-click the parameter to be reordered, and select Reorder Click the icon located next to the parameter value field.


Specify limits for a parameter and indicate whether the limit values are included or excluded from the acceptable range. The new parameter is added to the parameter list. Editing or modifying a parameter. In the specification tree, click a parameter below which the parameter to be reordered will be located.

Edit the parameter, then in the value field of the parameter editor, select Measure Between from the contextual menu. Creating a Parameters set using a macro. If you later change the value in Step 1, Step 2 and Step 3 will both have this new value and the formula that you used in Step 2 will be lost.

Displaying parameter values in the geometry area To display parameter values in the geometry area, you must have the Formulas Editor open.

Specifying a measure in a formula or. Edit the parameter, then in the edition box, right-click the value field and select Change step When a formula links two parameters, and if the input parameter has a tolerance, this tolerance will not be propagated to the output parameter. If you try to associate two parameters located in different components, the following error message is displayed: You can use this dialog box to measure the distance between two edges for example.

It is possible to valuate knowledveware boolean with a predicate instead of using operators. Incorporating Knowledgeware into model and analysis parameters allows other users to work with the model more effectively. If the imported parameters already exist in the document, the import process automatically updates the document. Measure between Set a parameter equal to the distance between two model entities.

In the specification tree, right-click the design table to be deleted, then select Delete.

Design Optimisation Using CATIA Knowledgeware Module

Check Create a design table with current parameter values. Tips and Techniques – Summary This part is intended for those of you who need a quick answer to their questions about the Knowledgeware capabilities. After you specify a range, Nonlinear Structural Analysis or Thermal Analysis displays an error message if an entered value exceeds the limits.


Associating a URL with a parameter. Clicking this button displays the editor of the relation which constrains the parameter the formula editor or the rule editor for example.

In the Parameter properties tab, check Constant. For more information on propagation, see Propagation.

CATIA Knowledgeware Infrastructure

There are several techniques that you can use to add Knowledgeware to analysis parameters. Right-click the value field of the window, and select Update Values CreateSet “Name of the new set”. In the Reorder window, select In or After and select a relation. The Reorder dialog box is displayed. For example, a solution sensor contains data in a list; click List to view or select commands that work with list data.

If you specify x in the Filter Name field of the Select parameters to insert dialog box, you will display all the parameters with the letter x in their name xA, xB, xC, xD, xE. In the Editor, select Length. Relations Parameters Formulas Design Tables.

The Formula Editor opens. It is possible to add ranges and default values to a design table. Only parameters which are not already constrained by any other relation or by any other design table can be used to create a design table. Note that the part number can also be modified in the Parameters Explorer in Knowledge Advisor. Note that if you try to delete a relations set containing another relations set with hidden relations, the message will be displayed. You can now reorder parameters sets and relations sets as you already could do for parameters and relations.
