Smallworld points to Microstation V8i cells are different sizes

I am translating a group of point objects at different rotations from Smallworld to Microstation V8i. The same object in Smallworld and using the same FME translator. The resulting DGN has different size cells to represent the same object. The point objects that are at 0, 90, 180 or 270 are the correct size when translated but other angles translate larger. I am open to any ideas on why this is happening and what can be done about it.

Thanks
