We will now create the left section of the spanner using the filleting and mirroring tools.  We will start by creating the arc at the end of the spanner.

1.Select the Curve Modeling tab curve-modeling-tab from the top Ribbon Bar.

2.From the Curve Modeling Ribbon Bar, select Center, Start, Angle Pts. Create an Arc with Center, Start and Angle
 
Command Prompt:
Center,Start,Angle Pts:: Pick center point or enter coordinates x,y and z

3.For the Center, type 0,0 in the Command Prompt command-prompt and then press Enter.

4.For Start, type 0,1.25 in the Command Prompt command-prompt and then press Enter.

5.For End, type -180 in the Command Prompt command-prompt and then press Enter.
Your drawing should look like the following:

Specify the arc end point using coordinate. Type -180 for angle

6.Now create a reference point located at 0,2.25 using the Point Create a Point command. The icon is located on the left side of the Curve Pane of the Curve Modeling Ribbon Bar.

Create a reference point at 0,2.25 using the Create Point command under the Points & Lines tab

7. From the Status Bar, toggle End Point Snap Toggle End Point Snap On On.

8.Now, select Rectangle Create a Rectangle.

9.For the 1st corner pick the point you just created and for the other corner snap to the End Point of the horizontal line as shown below.

For the 1st corner pick the point you just created and for the other corner snap to the end point of the horizontal line as shown
For the 1st corner pick the point you just created and for the other corner snap to the end point of the horizontal line as shown

10.This rectangle is one object – one multi-segmented curve. In order to be able to edit or modify this rectangle, it must be broken into individual lines.
 
Explode one or more CurvesTo do this, select the Explode icon. It is located on the far right side of the Edit Curves pane of the Curve Modeling Ribbon Bar.

11.Select the rectangle and then right-click or press Enter.
Now each line of the rectangle is a separate object.

12.Select Fillet Fillet 2 Curves.
 
Command Prompt:
Fillet:: Enter fillet radius [R=0.500000]

13.For Radius enter 0.5 and press Enter.

14.Select the 2 curves as shown below to fillet the curves.

Select the 2 curves as shown below to fillet the curves
The filleted curve is as shown below.
 
The filleted curve is as shown

15.Let's now create another arc.  Again, from the Curve Modeling Ribbon Bar, select Center, Start, Angle Pts. Create an Arc with Center, Start and Angle
 
Command Prompt:
Center,Start,Angle Pts:: Pick center point or enter coordinates x,y and z

16.For Center pick the end point on the upper right corner of the rectangle.

17.For Start pick the lower right corner of rectangle as shown below.

for start point pick the lower right corner of rectangle

18.For Angle, type in -90 and then press Enter to create an arc in the top right corner of the rectangle.

Specify an angle of -90 to create an arc in the top right corner of the rectangle
The created Arc is shown below:
 
The created Arc is shown

19.To clean up the corners we select Trim Trim a Curve again.

20.Select trimming curves to obtain the shape as shown below:

From the Modify tab, select Trim to trim the curves to obtain the shape as shown
