parts position API functions

We made a generic dll to animate aircrafts parts (like canopy) using keyboard keys, and I tried to use API get and set 'part' position or orientation sdk functions...without succes.The only functions I could use were API 'set frame' and 'show' and 'hide' parts.Actually, the dll can work with 3dstudiomax prepared frames, but it would be great to move inanimated parts too.Has someone resolved this point ?We started some tests with the dll and we will send it to the fly community soon.Laurent (ROTW member)
