Printing w/tubes

[Erin Lynch]

Hi Jarvist,

Thanks for your info. Unfortunately the system I'm working with has a number of
extremely large passages/chambers where we've surveyed around the perimeter,
so programs which use passage length to estimate tube diameter won't give
an accurate representation.

Cheers,
Erin
