Assessing the Weight Distribution

In Product Performance Assessment, you can assess the weight distribution along a predefined axis.

You can use this functionality only in the 3DEXPERIENCE and on the weight KPI. The weight distribution is represented by a graph and stored into a .csv file.


Before you begin:
  • Define the declared weight of the different parts of an assembly or retrieve the computed weight of the leaf products.
  • In Me > Preferences > Infrastructure > Product Finder, select Activate the Navigation Experience.
  1. To open your item including computed weight, click Search > My Content.
  2. Explore the item you have found.
    The item opens in the Navigation experience tab, in Product Finder.
  3. From the Compass, select Information Intelligence Apps and click Product Performance Assessment.
  4. From the Business Insight section of the action bar, click Weight and Balance .
  5. Optional: To verify if your data are consistent with the indexed components in Exalead CloudView, click Launch an Index Scan .
    An index scan starts. A periodic index scan (every 2 minutes) is automatically defined during the installation of the app.
  6. Select a root product or an occurrence in the 3D area:
    When an item is an occurrence, you can read Occurrence under its name in the tab.
    Note: The inertia matrix and the center of gravity depend on the item's position. If you select an occurrence, the center of gravity is displayed in the assessment, and the value of the center of gravity is repositioned according to the root product.
  7. Optional: Select a configuration or a filter.

    For more information, see Using a Zoning Filter.

    If several configurations are available for this item, you can select one of them. You can also compare different configurations.
    Tip: When your component has more than six configurations, a search box is displayed and you can filter the list.

    The web page displays the consolidated KPIs for this item. If you hover over the chart, a tooltip displays the KPI values.

  8. Click the weight KPI.
  9. Click Weight Distribution .
  10. Turn the root into the desired position.
    In a Quality percentage box you can choose the number of points necessary to compute the weight distribution graph. The higher the number, the more accurate the weight distribution is, but the computation may take longer. The points are computed on the fly.
  11. From the list, select a number of points and click Launch Computation.
    The weight distribution takes several parameters into account:
    • The structure's weight is projected on the view plane in the 3D area (Plane A).
    • The weight curve has the O origin on the bottom-left corner of the 3D area window.
    • The x axis is the direction DirA parallel to the 3D area's horizontal line.

    The graph is computed according to an O - x axis.

  12. To generate a table view of the results, click Download CSV.

    The table contains a line for each point and three columns:

    • The first column indicates the distance starting from the first point on x axis (unit: meter).
    • The second column shows the weight between the previous point and the actual point (unit: kg). The sum of all these planes corresponds to the weight of the whole assembly (see step 7).
    • The third column shows the weight tolerance for each plane (unit: kg).
