In this step we will create the wall that pass between the two center bosses.

1.Again, activate the Right View and then from the Display menu on the View Toolbar, select Wireframe Display.

2.From the Curve Modeling tab, select the Circle on Point command.

3.For the center point select the grid point shown below.

4.Enter 0.25 for the diameter and press <Enter>.

5.Press <Enter> again to repeat the command.  For the second circle select the grid point shown below and then enter 0.10 for the diameter and pres <Enter>.  We will use these two circles to locate the corners of a polyline that defines the cross-section of the connection wall.

6.Now from the Curve Modeling tab, select the Polyline command.

7.From the Status Bar toggle on the Quad Point Snap and toggle off all of the other object snaps.

8.We will be drawing a 4-sided closed polyline that encompasses the yellow area shown in the image below.  For the start point of the polyline select the quad point on the right side of the lower 0.25" diameter circle at the #1 location shown.

9.Then continue, by selecting the Quad point located at the right side of the upper 0.10" diameter circle.

10.For the next point in the polyline select the Quad point on the left side of the upper 0.10" diameter circle at the #3 location.

11.Then continue by selecting the Quad point at the #4 location.

12.To complete the polyline select the Quad point at the #1 location where the polyline started.  The Polyline command will end automatically when the end point coincides with the start point.

13.Now you can delete the two circles.  Just select them and press the <Del> key.

14.Now we will extrude the 4-sided polyline to create the Connecting Wall.  First select the polyline we just created.

15.Now go to the Mesh Modeling tab and select the Extrude Mesh command again.

16.Drag the cursor to the Front View and drag the length of the extrusion to the right of the center line where the selected polyline resides.  Refer to the image below.

17.The point we want is not on a grid point, so with the extrusion previewed (do not select a point), go to the command prompt and type in the distance 2.300 and press <Enter>.  
 
The Connection Wall is created.

18.Now from Iso View 1 select the Connection Wall to display the Graphic Manipulator.  If you do not see it, make sure it is toggled on from the Status Bar .

19.Pick the red X Axis arrow and type in -1.15 and press <Enter>.  The Connection Wall should move into place at the center spanning between the two bosses as shown in the image below.

20.Now lets unite the Connection Wall with the body.  Go to the Mesh Modeling tab and select the Unite Mesh command.

21.For the first mesh solid, select the body.
