Modeling > Operate > Booleans > Add > Areas
In the Add Areas window, click on Pick All.
(Alternatively, the command line code for the above step is
AADD,ALL.)

Parameter Circle 1 Circle 2 Circle 3
WP X 80 0 0
WP Y 50 20 80
Radius 30 10 10

Create the Bolt Holes
We now want to remove the bolt holes from this plate. Create the three
circles with the parameters given as follows: Now select
Preprocessor > Modeling > Operate > Booleans > Subtract > Areas
Select the base areas from which to subtract (the large plate that was
created). Next, select the three circles that we just created. Click on the
three circles that you just created and click OK.
(Alternatively, the command line code for the preceding step is
ASBA,6,ALL.)
Now you should have the following:

3. Define the type of element:
As in the verification model, PLANE82 will be used for this example:
Preprocessor > Element Type > Add/Edit/Delete
Use the Options... button to get a plane stress element with thickness.
