Functionalities where simplification is present:
|silhouette, wrapping, vibration volume, merger result|
Note: If your are not
working in alternate shape mode, it is strongly recommended to use the

About Reference Product
You can now select any node within the specification tree (terminal/non terminal) and even multi-select them provided that you are not working in alternate shape mode.
Select the product to you want to simplify (i.e. Product1) in the specification tree or in the geometry area.
Click Simplification in the DMU Optimizer toolbar. The Simplification dialog box is displayed
|The number of triangles representing the selected product is displayed in the number of triangles field:|
Setting the Accuracy:
Defines the simplification calculation accuracy. A higher value results in slower computation time, but a "lighter" simplification representation.
Enter the desired value in the Accuracy field for instance 5mm.
Click Preview. The progress bar is displayed letting you monitor and, if necessary, interrupt (Cancel option) the calculation.
|The number of triangles representing the simplification result is displayed in the Number of triangles
field as shown below:
The simplification representation is coarse but the number of triangles has been drastically reduced.
Better Simplification result
From R17 onwards, a new algorithm is used to generate a better surface,
without holes, inside-out triangles, overlapping and duplicated
Note though, the calculated deviation is different from the
former algorithm, leading to a change in number of triangles.
There can be more triangles than with the former algorithm (R16 and

|Now,we are going to compare the two products, please refer to Comparing Products in DMU Space Analysis User's Guide|
Select Start > Digital Mockup > DMU Space Analysis...
Click Compare Products in the DMU Space Analysis toolbar: Visual comparison is the default comparison mode.The Compare Products dialog box appears.
Select one of the products you want to compare
Select the other product (new version), Product1_SIMPLIFICATION1.1
|You are not satisfied with the result, you are going to simplify again with a finer accuracy value|
Switch to DMU Optimizer workbench selecting Start > Digital Mockup > DMU Optimizer
In the SIMPLIFICATION.CATProduct window, click the Simplification icon in the DMU Optimizer toolbar.
Enter the desired value in the Accuracy field, this time 2mm.
Click Preview to obtain a preview. The progress bar is displayed letting you monitor and, if necessary, interrupt (Cancel option) the calculation.
|The number of triangles representing the simplification result is displayed in the Number of triangles field as shown below:|
|This time the simplification representation is finer and the number of triangles result is still valid in terms of performance gains.You are satisfied with the result|
Click Save. The Save As dialog box is automatically displayed:
Select .cgr file from the Save as type drop-down list and enter a meaningful name if needed.
You can manage automatically your Simplification result as an alternate shape of the initial component.
The simplification result will be added as a new representation of the
