Creating the Feed Line

Create a feed line with start point (0, 0, 0) , end point (0, 0, -0.551) and label Feedline.

myPoint1 = cf.Point(0, 0, 0)
myPoint2 = cf.Point(0, 0, -0.551)
myLine = myProject.Contents.Geometry:AddLine(myPoint1, myPoint2)
myLine.Label = "Feedline"

Figure 1. A line with start point (0, 0, 0) and end point (0, 0, -0.551).

1. Define two points, myPoint1 and mypoint2 (see Defining a Point).

   myPoint1 = cf.Point(0, 0, 0)
   myPoint2 = cf.Point(0, 0, -0.551)

2. A line is a geometry object and since there may be multiple geometry objects in the model, it is part of the GeometryCollection.
3. Search for GeometryCollection in the Help¹.
4. In the Help, under GeometryCollection > Method List, search for methods that are applicable to lines:
   • AddLine (properties table)
   • AddLine (startpoint Point, endpoint Point)

   To create a line, we will use the method:

   AddLine(startpoint Point, endpoint Point)

5. Fill in the startpoint and endpoint (use the points, myPoint1 and myPoint2):

   AddLine(myPoint1, myPoint2)

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

      :AddLine(myPoint1, myPoint2)

   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:AddLine(myPoint1, myPoint2)

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

      myProject.Contents.Geometry:AddLine(myPoint1, myPoint2)

7. Add a reference to the newly created line:

   myLine = myProject.Contents.Geometry:AddLine(myPoint1, myPoint2)

8. Set the line label to Feedline:

   myLine.Label = "Feedline"

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