Unioning the Model

Union all geometry in the model (Feedline and Patch) and set its label to Union1.

myUnion = myProject.Contents.Geometry:Union()
myUnion.Label = "Union1"

Figure 1. The model tree showing the union of Feedline and Patch with label Union1.

1. The union operation is a geometry object and since there may be multiple geometry objects in the model, it is part of the GeometryCollection.
2. Search for GeometryCollection in the Help¹.
3. In the Help, under GeometryCollection > Method List, search for methods that are applicable to the union operation:
   • Union (geometrylist List of Geometry)
   • Union ()

   To union all geometry in the model, we will use the method:

   Union()

4. Determine the syntax to prepend to Union():
   1. Since Union is a method, it is indicated by prepending a “:” (colon).

      :Union

   2. In the Help, under GeometryCollection > Usage locations, note the following:

      ModelContents object has collection Geometry.2

   3. Click ModelContents.
   4. In the Help, under ModelContents > Usage locations, note the following:

      Model object has property Contents3

      Since we know that Model is the one of the top levels in the model tree, the result is then:

      Contents.Geometry:Union()

   5. Since the project is the highest level, we prepend our reference to the project:

      myProject.Contents.Geometry:Union()

5. Add a reference to the newly created union:

   myUnion = myProject.Contents.Geometry:Union()

6. Set the union label to Union1:

   myUnion.Label = "Union1"

   Tip: View the Union (object) in the Help for a short example.
