Thanks, Lobo, but I don't think I'll ever use Hexagon again after yesterday.  I just don't see any advantage at all to the workflow or tools, compared to Blender.  It literally felt like modelling with a handicap of some kind.  I finally modelled the ported cube about 20 times last night in Hex, and the very best time I could achieve was just over 1 minute, and that's only if I didn't make any selection errors.  I honestly don't see how people find Hexagon easy. The ONLY thing I found particularly useful in Hexagon was the Lay-On tool.  3dsmax has something like that called the Placement Tool.  I haven't found anything in Blender like that yet, but doesn't matter for every day modelling.  I'm happy to stick with Blender.
