From the Sketch section of the action bar, click Cylindrical
Elongated Hole .
Tools Palette displays boxes
for defining the cylindrical elongated hole.
Specify the coordinates for the center of the circle in the Tools
Palette and press Enter.
The center is used to create both the big radius (radius and angle of
the cylindrical elongated hole) and the small radius (circular extremities used
to define the cylindrical elongated hole).
Specify the coordinates for the arc's start point and press
Enter.
The arc appears as a construction arc.
Note:
You can
also specify the big radius and angle of the arc.
Specify the coordinates for the arc's end point and press
Enter.
The arc appears as a construction element.
Note:
At this step, you cannot
define the arc's big radius and angle.
Specify the coordinates for the point on cylindrical elongated hole and press
Enter.
In other words, you are defining the small
radius. This small radius corresponds to the width of the cylindrical
elongated hole, relatively to the circle center.
