anyway... switching to the top view... I used the corners of the working grid as reference points, and moved the points on the extrusion line down to the "bottom" of the grid... left point on the bottom left corner of the grid, right point on the bottom right... Then, making sure that the right (2nd) point is selected, use the pen tool to "connect-the-dots" to the other two corners, and finally back to first, closing the square... switch back to the director's view and you should have your frame.
