Strategy for Geometry Creation

...

In this step we will create a new sketch in the XY Plane. This step is required for the boolean operation that we will carry out later in the geometry process. It allows us to create two distinguishable geometries, in the xy plane.
Click on XYPlane in the Tree Outline and it should highlight blue. Then click on the New Sketch button, .

Create Outer Circle and Dimension

Now, create a circle centered around the origin in Sketch 2 . Set the diameter of the circle to 64m. You can click the "fit to window" button shown below to see both circles.

Outer Circle Surface Body Creation

...

Then set Operation to Add Frozen as shown in the image below.

\
Then, click Generate

Carry Out Boolean Operation: Subtraction

...

Create > Boolean .
First, set Operation to Subtract . Next, use the face selection filter, , to apply the outer circle surface body as the Target Body . Then, use the face selection filter, , to apply the inner circle surface body as the Tool Body . In order to select inner circle which overlaps with the outer circle, you may have to click on the planes to the lower left as shown below.

Lastly, click Generate . At this point if you zoom into the center of the circle you should see the 1m diameter hole, as shown below.

Create a Bisecting Line

The purpose of this step and the following two steps is to imprint a line onto the geometry that will, allow for radial edge sizing in the meshing step.
