In this step we will model the body by creating an extrusion.

1.Activate the Top View tab by selecting anywhere in the viewport.

2.Select the Curve Modeling tab from the top Ribbon Bar.

3.Now select the Arc Center, Start, Angle command.

4.In the Status Bar make sure the Grid Snap is On .

5.For the center point select the grid point shown below.  The status bar will track where your cursor is located in World Coordinates.  Move the cursor until the grid point at 1.5,0,0 is located and pick it.

6.Following the command prompts .  It says to select the start point of the arc.  Locate and select the start point shown below.

7.For the arc end point move the cursor clockwise and pick the end point shown.  You will see that the arc is previewed as you move the cursor.

8.Now we want to draw another arc, press <Enter> to repeat the command and select the center, start and end points shown below.

9.Now we want to draw a line to connect the two arcs across the top.  From the Curve Modeling tab select the Line command .

10.For the start point for the line select the grid point located at the top end of the arc of the left and then for the end point of the line select the top end of the arc on the right.  Optionally, you can set the Object Snap to End Point from the Status Bar and select the end points of the arcs to draw the line.

11.Press <Enter> to repeat the Line command and draw the second line connection the two arcs across the bottom.  Your drawing should look like the image below.

12.For modeling its best that you merge your profile geometry into a single curve entity.

13.Window select the geometry (both arcs and both lines) and from the Curve Modeling tab select the Merge Curves command and then right-click the mouse to merge them.  If you pick anywhere on the geometry you will see that one curve is now defined.

14.Now lets create the body by extruding our profile curve.  With the curve selected, change to the Mesh Modeling tab and select the Extrude Mesh command.

15.For the extrusion distance, drag the cursor down to the Front View and select the grid point shown below.  Its located at 2.0" below the selected curve.
