Fixing that Little Problem, with HEXAGONS

After talking to James (my tutor) about my problem with the STL files and the compression and blah blah blah he showed me something very cool. Solidworks has a very neat little feature that allows you to wrap sketches that you've made in the program around another object, like this :

and then extrude them. What he showed me was a hexagon pattern (there's also a button that allows you to make patterns, I'm liking this program more every day) wrapped around a cylinder, which was then hollowed out to make what he called a "futuristic capillary", I like it.

Needless to say I shamelessly copied his idea and immediately ported it into 3DS Max and it SOLVED MY PROBLEMS: here's what I whipped up (its a very basic render, i'll do a better one later):

Also one more thing; if you extrude inwards is it called intruding?
