Desenvolver um Software

Imagine that I have an Excel spreadsheet that contains lots of (x, y) coordinates. These coordinates where the final result of formulas. I used as input to these formulas some numbers that change very often. Lets suppose that if you link all of these coordinates, you obtain a square. And I want the drawing of a square to be shown on a Illustrator doscument. Your task is: You will have to find the code (pobably VBA code) that will link both softwares (Excel and Illustrator), in a way that everytime I click on a button on Excel, this drawing of a square will show on Illustrator document. It's not hard. I understand very little of VBA and I have set up this bridge thing between Excel and AutoCAD all by myself. If you are a super specialist on VBA, Excel and Illustrator and tell me this task is really impossible. Ok, we try to find another way. Check the image I posted to get a better understanding of the task.
