How do I make an eraser tool?

Hi folks,

I am working on a historical map tool (http://www.barbaareducatie.nl/millo) for classrooms which also happens to have a simple draw tool (using the canvas object) to draw stuff like arrows on the maps.

Some teachers request an eraser tool now and I don't seem to be able to do that. The canvas object doesn't have an erase command and the solutions I can find here don't seem to work for me (pasting an object with the "destination out" doesn't do anything). Is this possible at all?

Hey I used the destination out effect and pasted the object to mouse location on right click and it did the trick. Check out the capx to see how I did it.

That works! I was doing it totally wrong. You saved me, thanks a lot dude!

You are very welcome. Glad I could help
