I have had no success in quilting a completed top with my embroidery machine, although many others do so. BTW, as far as the machine is concerned, a quilting design and embroidery design are the same thing. You have to hoop each embroidery design separately. I can't seem to get the weight off the arm so the embroidery unit can do its thing, and also have problems getting the embroidery in the right place. I have done quilt as you go with my embroidery machine, quilting the blocks individually, then joining, which worked out well, but not a whole quilt.
As far as the 5D quilt design creator package, it looks like it will create a design that you can stitch out on a computerized quilter or an embroidery machine. The previous verson for the Qbot will put out a .hus embroidery file that you can use on your embroidery machine AS LONG AS IT FITS IN THE HOOP!!! I would contact your local Viking dealer. He/She should be able to give you a demo and explain what it does.
