Creating Overall Dimension

You can use the Overall Dimension to create a dimension on the overall length of several electrical components, a dimension having a start and an end point, taken as a whole. The Overall Dimension command is available in the part's context. You can reuse a reference measure point (3D marker) for the creation of another overall dimension.

The scenario illustrates the creation of overall dimension on extracted content and on flattened content.

Before you begin: Use the default background to be able to see the dimensions.
  1. From the Dimension section of the action bar, click Overall Dimension .
    The Electrical Dimensions dialog box appears.
  2. Hover the pointer over the different segments to see the measure points.
    The visible measure points for supports and protections are the entry and exit points. Ctrl + hover over the support or protection to show the middle measure point. To make this a default option, select the Measure Point is always the middle of support and protection check box under Electrical Dimension, available in Me > Preferences > App Preferences > 3D Modeling > Electrical and Electronic Systems > Electrical Mfg. Preparation > General expander.
    Important: If the chosen segment is not selectable, a tooltip displays an error message.
  3. Click the required measure points.
    On 3D Extracted Content On Laid-Out Content




    You just need to select key points that intersect with two branches or electrical geometries.

    You can first select an electrical component, defining the reference measure point, and a reference marker is created (R5 for example). Then select a second measure point, defining the pointing reference, and a new dimension marker refers to R5 (106.861mm/R5 for example).

  4. In the Electrical Dimensions dialog box, click OK to validate.

    On 3D extracted content On flattened content




    Note: You can reuse a reference measure point (reselect R5) to create several electrical dimensions. In the example below, the reference 3D marker is R5 and it is used by two dimension markers (106.861mm/R5 and 161.996mm/R5).

    When a 3D marker already exists, select it again or select the electrical components or measure points. It is not possible to select dimension markers because they already contain dimension information. Only FTA annotations are allowed as new selection types.

    You can specify the offset distance between the dimension line and the dimensioning element in the Offset distance box, available under Dimension offset in Me > Preferences > App Preferences > 3D Modeling > Electrical and Electronic Systems > Electrical Manufacturing Preparation > General section. For more information, see General.

Warning:
  • The electrical dimensions created in Electrical Manufacturing Preparation have the same limitations as the FTA command.
  • The measure point created on a segment by the user can only be a point on curve. The curve is an electrical curve.
  • For information about the import of FTA dimension from V5 to 3DEXPERIENCE, see Electrical Manufacturing Preparation File-based Design Import.
Note: When the electrical geometry is not flattened, the electrical dimensions are only indicated with start and end points with the overall dimension written on the second point.
