Assign Attribute Above or Below Solids

On the Shape tab, in the Utility group: Click Assign Attributes Above or Below Solids to assign attributes to design elements that lie above or below solid regions. (Ctrl+Alt+A,A)

Since attribute values can be assigned for text elements and layer triangulations, this option is also available on the Text and Triangulation tabs, in the Utility group.

Do the following:

  1. Select the Source of the data that will be used as input to the function:

    Selection Design elements you have interactively selected in the Design Window.
    Visible Design elements that are visible in the loaded layer. Elements that have been specifically hidden are excluded. This a quick way of selecting all visible elements in a layer without having to explicitly select them.
    Layer One or more layers that you select. Names of layers currently loaded in the Design Window are shown in bold.

     

    For large datasets, for performance reasons you may prefer to select a layer rather than load that layer and select all of the elements in the layer.

    Selecting a non-applicable layer will have no effect. In most cases, an error icon will indicate that the chosen input layer is not valid. Hover over the icon to view a validation hint.

  2. Choose a screen plane. Note that this will be used as the selection plane.

    Plan Use Plan View (looking top down).
    Camera Use the current Camera view.

    * The current plane of the view in the Design Window is not changed.

  1. Use the drop-down to select a Region Layer.

  1. Use the drop-down to select the Region Attributes to assign to the design elements that fall inside the specified regions.

  1. Choose a Matching mode to assign:

    Elements that are above the specified region(s).
    Elements that are below the specified region(s).

  1. Finally, click Apply to assign attributes by solid regions.

    2. Check that the result of the operation is what you expect. If necessary, use CTRL+Z to undo.

    Note: It is recommended that you do not use this tool where you have regions which overlap. If selected elements fall within more than one region, the attributes of the last region encountered are most likely assigned, however this is undefined behaviour and the assignment may be unpredictable.
