Computing Mean Dimensions

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

This task shows you how to compute the


Before you begin:

You must define the tolerances that you want before computing mean dimensions. For more about tolerances, see Infrastructure User's guide Version 5.

  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 just 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 .

    A dialog box appears informing you that the operation is performed. You then just need to update the 3D shape to observe the result.

  3. Click Update All to integrate the modifications to the 3D shape.

    Note that the update options set for your session (for more see General) 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.

  4. If you wish to go back to the previous state, click Mean Dimensions again.

    A dialog box appears informing you that the 3D shape will be resized to nominal dimensions. Original tolerance values, when re-computed, are always expressed in numerical values.

  5. Click OK to confirm.

    An additional message appears to inform you that the operation is performed and prompts you to update the 3D shape.

  6. Click OK

    to close the message window.

  7. Click Update All to resize the 3D shape to nominal dimensions .

    Keep in mind the following:

    • To ensure that you can run the command properly, do not use features having the same name.
    • If parameters are driven by formulas, the application deactivates these formulas to compute mean dimensions.
