Create a Fill Pattern with a Fill Boundary
A Fill Pattern allows you to fill a defined region with a predefined cut shape or pattern of features. You can sketch a boundary to be used as well as control the pattern layout. To see how to do this, begin a new Part document and create a base flange. Create a sketch on the base flange to use as your Fill Boundary. Do not put other shapes in the sketch since they will be filled also. I created a simple kite shape. Note that this can be any closed loop shape. Then, create a centerline and a point at the midpoint of the centerline, as shown in Figure 1. The point will be used to define the center of the pattern.

After exiting the sketch, pull down the “Insert” menu and pick Pattern/Mirror – Fill Pattern, or pick Fill Pattern from the Feature CommandManager. In the graphics area, select the Fill Boundary sketch.

In the Fill Pattern PropertyManager, under Pattern Layout, there are four kinds of layout patterns to choose from. The pattern instances are laid out concentrically from the seed feature. If you look really close at the buttons, you will see that the center circle on each is red, representing the seed feature. For this example, choose the Perforation button. Set the Instance Spacing to ‘13’. The pattern direction has already been set for you, but this is customizable as well.

Under Features to Pattern, click the Create seed cut radio button. This allows you to use a predefined shape instead of having to create a seed feature. Click the Polygon button and set the Polygon Sides to ‘6’. Set the Outer Radius to '5'. By default, the pattern seed feature is located at the center of the sketch since Vertex or Sketch Point has not been defined. This is where the centerpoint comes in. Click in Vertex or Sketch Point, and then, pick the point that you created at the midpoint of the centerline. Now, the center of the pattern is at that point, exactly where you defined it to be, as shown in Figure 2.

Click the green check mark button at the top of the Fill Pattern PropertyManager to accept the settings shown in Figure 3.

In the FeatureManager design tree, right click on the Fill Boundary sketch and pick Hide. You now have a Fill Pattern in your Fill Boundary, as shown in Figure 4.
