Re: How to cut a circle in a polygon?

Hi,

With wide shots the alpha solution works well. I am not sure if it would work very well with closeups.

This is how I would do it:

Take a circle spline, clone it using a grid array into the desired grid you want.
Then collapse the cloner object to get the splines (you will get a null object with all the splines as children). Now if the initial circle was a parametric object, you will have to select all the circles and convert them into splines as well.
Then with all the splines selected, do connect+delete.
You will get one single gird of circles spline.
Now if you want a rectangular grid, draw a rectangle around the grid of circles.
Make the rectangle editable (if not already).
Connect the grid and rectangle together.
Apply a Extrude Nurbs modifier.

Now this solution gives you real geometry. You can also bevel the edges of the circle grid easily.
