I got the drill plugin installed and it works great as long as I have parallel faces, so a rectangular block. I have an angle block that I need to drill a hole in, and it doesn't work for that. Any ideas on how to make this cool plugin work for angle blocks? That is, where the bottom face and the top face are not parallel.

You can have a look at Fredo6s VisuHole plugin.
