Zafar,
If my cnc wire bender project pushes through, then you are the man behind the success

I used Illustrator to create vector graphics as it allows me to readily revise, change, move, and create effects. I then export it as png format. If changes need to made, I can always go back to Illy to make the changes. Drawing programs like Paint Shop, Photoshop, etc. takes much longer to make changes or corrections as it is in bitmap format.
