I have a problem doing a very simple operation

[Guest]

Yes, I already read postings and documentation. What I want to do is doing a reverse erasing of part of a circle. I draw a box for the part of the circle that I want to erase. I use a clipping mark but the problem is that it keeps what is inside of the mark (box). I want to do the contrary, I want to erase what is inside of the box.

It should be very simple operation but I am stuck. Help!

Look at the Pathfinder Pallet, or Object > Compound Path > Make

[SJRiegel]

You can also use the Transparency Pallet

The results of the  methods will differ somewhat

Compound Path > Make will give the same result as the Pathfinder Pallet

This is what I get as a result. I just want to remove the quarter of the circle...

If I understand what you are trying to do, you just need to take the next step of selecting the center point, and deleting it.

It that is your intended result, you could also achieve it my clicking on a segment of the circle with the Direct Selection Tool (solid arrow), and pressing the delete key.

Thank you, thank you. It worked and I will remember how it is done.

I start to remember what I did in the past. Now, the box erases part of the circle but I have the contour of the box inside the circle The rest of the box disappears, which is a progress. But how to erase the part of the box contour inside the circle?

I am ambarassed to ask so basic questions and I thank you for your help.
