Union Triangulations

On the Triangulation tab, in the Split/Merge group: Click Union Triangulations to Boolean UNION a set of triangulations. (Ctrl+Q,U)

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. Use the drop-down to select an Output Layer.

   Tip: In the Layer Selection pane, you can right-click on the Layers node (or a folder) to Add a new layer.

3. Click on the ellipsis to use the Expression Editor to create a Grouping Expression that will be used to subdivide the input source data into groups. The action will be applied to each group, rather than to the input source as a whole.

   For example, you want to apply an action to each of the Strips that comprise a Pit Solid:

   GetText(IdentifiersStrip)

   

4. Finally, click Apply to union the triangulations.

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