CorelDRAW Graphics Suite X5 :: Mirror / Reflect About A Line But Line Is Inside Object

how to mirror about a line, but the line was outside the object.

I now have a need to mirror about a line but the line is partially inside the object (so after mirroring the object would be overlapped). When I select both objects and try to create the mirror, the "axis" of the reflection is simply the edge of the object, not the line.

When the line was outside, that worked simply because when you selected both objects the line brought the outside of both selected objects to that point so it simply mirrored / reflected at that point (the line). So the line was not truly acting as a point of reflection. Hope that made sense.

I think I'm about to buy Cadtools from Macromonster but I would like to know if Draw has a way of acheiving this. Hey I may find out Cadtools can't reflect when the line is inside the object.
