Hay Guys. After hours of frustation, I've decided to ask this question out in the forums. I'm making a philips screw for my project. I've almost got it except for the cavity for the screwdriver on the head. For that I decided to download a part of philips screwdriver from grabcad.com. The idea was to place the screw driver on the head, position it and then subtract it from the head. I have an autocad background and it was pretty easy in that. But I just cant seem to move it around. I tried moving them in assembly too but it didnt work.

There are a few things you \guys could help me with. First, Is there an easier way to create the cavity? and how do I position the screwdriver part over my screw head?

Any help would be greatly appreciated.
