We will next trim off the unwanted edge. Under Modify Tab, select Trim. Execute the trimming in Graphic window as shown below.
 

 
At this point, we have the outline of the crank done. We need to add the cut out in the middle of the crank. First start with a sketching of the cut-out. Under Draw tab, click on Line execute drawing in Graphic window as shown below.

 
We would want the four points of the cut out we created to be of following coordinate.
(-0.7972, 0.1642)
(0.7972, 0.3248)
(0.7972, 0.9744)
(-0.7972, 1.1368)
Unfortunately, there is no easy way in specifying the coordinates of a point. So we will have to dimension them accordingly using the dimensioning tools. Click on Dimensions tab and use General tool and execute the dimensioning as shown.
 

 
Under Details View, enter the value for the dimensions.
H5 = 0.7972 in
H6 = 0.7972 in
L4 = 0.1642 in
