Drilling a hole in a complex object takes some work but it can be done. Here is how I've done it. 1. Take a cylinder and place it where you would like the hole to be, reverse the normals on the object now, makes it easier later. Also remove the faces on the top and bottom of the cylinder. 2. With the A select button on, select the cylinder. 3. Attach the cylinder to the desired object, making one object. 4. Change to the B select button 5. Align your view to be looking down the cylinder. 6. Using Select/Face/Region 1 select all the faces that are around the cylinder, including the cylinder, then INVERT the selection set. 7. Use Display/Hide/Face to hide everything in the model but the cylinder and the intersecting faces. 8. Now it gets fun, looking down the cylinder, remove all faces that are completely within the cylinder's circumference. 9. Modify/Edge/Divide all faces that cross the circumference. You may have to do this a few times. 10. And here comes the hard part, you have to use several views to move vertex points to align, then weld. Going back to the A select button so you can see the cylinder walls, helps. I'm afraid there is no 'simple' way do it, otherwise.
