Hi Elaine, thanks for the hint! I found that Erase Octant definitely draws a box but If not aligned with the z axis the hole has the dimension of the projected axis - if its angle is large the hole is large and vice versa. I am not happy with the sphere eraser as I want to rather make along channel! Any other suggestion? Thanks again, best?
