I'm guessin' that both objects just dissapear?

Well, there's a way around that. You can cut out the outside hole and then cut out the inside peice from another copy of the same geometry, before putting it into the hole already created.

I've included a file for you to have a look at.

On the left side is a maple leaf and a cylinder, and on the right is a slightly smaller leaf, and a cylinder.

Go about it thus:

MAKING THE HOLE
1) Select the left leaf and do Polygons->Seperate
2) Select the cylinder and one of the 7 parts
3) Do a boolean->Difference
4) Repeat steps 2&3 for all 7 parts of the leaf on the left

MAKING THE FLOATING PART INSIDE THE HOLE
1) Select the right cylinder
2) press Shift-D 6 times, so there's one cylinder for each of the 7 parts of the leaf. DO NOT MOVE THEM.
3) Select a cylinder, select a leaf part, do boolean->intersection
4) Repeat step 3 for each of the 7 leaf parts and cylinders.
5) Select these 7 leaf-parts and combine them. Notice they're no-longer flat.


You should now have a cylinder on the left with a maple leaf shape cut out of it. On the right you should have a maple leaf that's slightly smaller that the hole.

I picked a shape a little too complex to work nicely, but give it a go and you'll see how to go about it.

Simon.
Btw, I've included these instructions in the zip file, for offline use.
