Hi Michael.
> Can you please describe this one a bit more? If you could also post the .3dm model file that may help me understand.

Without all this, of course, you can do, and what you have done will cover most of the tasks.

I can't imagine how difficult it was for you but judging by the time spent it was a rough trip with a big backpack and a bunch of boy scouts. :)
With the successful completion of the journey!
