Nesting of parts in BobCAM

I am still in my evaluation process of various CAD/CAM programs and at
the moment working with BobCAD. This so far has been the easiest to
operate and has successfully loaded my AutoCAD DXF files with the proper
contour shapes(in a previous post, I had problems with importing a DXF
into DesKAM)and appears to have created the proper G-code to cut the rib
shape properly.

The question I have now is, does anyone know the process for nesting
multiple parts into BobCAD? I tried the "copy", but that did not work.
Would I have to draw the multiple parts in AutoCAD and then export that
drawing with the cutting table dimensions already in place. I will have
a cutting space of 24" x 48".
