Computing Mean Dimensions

You can compute mean dimensions of a 3D shape using the Mean Dimensions command.

Before you begin: You must define the tolerances on a 3D shape before computing mean dimensions. It allows you to activate the mean dimensioning system. For more information about tolerances, see 3DEXPERIENCE Native Apps User's guide.
  1. Before computing mean dimensions, apply the Edit Parameters contextual command to the feature of interest to display parameters, then take a look at the 3D shape you have opened.
    The 3D shape includes three tolerance parameters as shown below.

    Tip: To access tolerance values, double-click the parameter of interest, then use the Tolerance > Edit contextual command.
  2. Click Mean Dimensions in the App Options panel.
    A warning message appears informing you the active dimensioning system. It also gives you an option to either convert the active dimensioning system or retain it.
  3. Click Yes to resize the 3D shape to mean dimensions.
    An additional message appears to inform you that the operation is performed and prompts you to update the 3D shape.
  4. Click OK to close the message window.
  5. Click Update All in the standard area to integrate the modifications to the 3D shape.
    Note: The update options set for your session do not affect the Mean Dimensions command behavior: you always have to explicitly update your 3D shape. Mean dimensions are displayed around the 3D shape.


    Tips:
    • If you want to go back to the previous state, click Mean Dimensions again. The 3D shape will be resized to nominal dimensions . Original tolerance values, when re-computed, are always expressed in numerical values.
    • To ensure that you can run the command properly, do not use features having the same name.
    • If parameters are driven by formulas, the app deactivates these formulas to compute mean dimensions.
