Use the Radial Array tool in Apps. Draw a single circle the size you need the 100 holes to be and then use the array tool to duplicate and place it in a circle. IN the app set the size of the outside circle and set the shape count to 25 (Easel will do 30 max but 25 makes the math easier). Create the 25 in the circle.
Then go back to the original circle and repeat the process BUT without de-selecting it go to the “Shape” box and enter 3.6 degrees in the Rotation box.
Now select the original circle again and repeat the process but this time rotate it 7.2 degrees. Do it again and rotate that group of 25 circles 10.8 degrees. Each time you need to add 3.6 degrees.
You should then have the 100 circles evenly spaced in a circle. Now Combine them (do not include the original circle). Now draw a circle the size you want for the center and use Easel’s centering tools to place it dead center.
Why 3.6 degrees? 360 divided by 25 = 14.4 degrees this is the spacing of the first set of 25 circles. But you need 3 more sets or 4 total. Divide 14.4 by 4 and that yields 3.6 degrees between each set.
