In the Components to Pattern field, click on container In Direction 1, select barge-1 barge Notice the grey arrow showing the direction of the pattern. If the direction is not correct, click on Reverse Direction. 92. In Direction 1, enter a Distance of 20ft and Number of Instances of 3.

26 93. In Direction 2, select barge-1 barge In Direction 2, enter a Distance of 8ft and Number of Instances of 3.

27 95. Click when you are done.

28 96. Perform the same mates and linear patterning to create a 2x3 row of container2 at the front of the rake barge. Your completed barge assembly should look like this 97. Click on the Evaluate tab and determine the Mass Properties of your completed barge assembly. Now open the MS Word or Notepad document that includes the Mass Properties of your rake barge part and compare the center of gravity to that of the assembly. What has occurred?

29 98. By changing the values of your distance mates in the assembly, you can move the containers forwards or backwards in the barge assembly. To do this, expand your Design Tree and find the mates for container Right click on the distance mate and select Edit Feature to change the value of the mate. This will allow you to move the containers forwards or backwards on the barge Design Challenge: Move the containers to arrive at a center of gravity as close as possible to the center of your rake barge. Save your work. Congratulations! You have completed Part V of this lesson.
