Glad to help. Your welcome.

I know, i have been thinking if it is really worth it, it might give too much weight to the model, for a barely visible feature, but in either case even if ultimately i don't use it, it will still be useful to learn some more sketchup skills.
I couldn't agree more. Even if a technique/trick is not used ultimately, one always wishes to knowhow it could be done (though we were cast out of the Paradise for this urge to knowthings...
)
Eric: perfect as usual...
Solo: really cool. And yes, Eric, that's me!

eric,
very nice tut. it reminded me of the way ancient builders used to cut stone to make twisted columns. the process must have been the same.

A threaded tube is an interesting special case. I did a model a thousand threaded holes. SU just did not want to deal with all the geometry even though it was a component. Moves take too much math. I just painted the inside of the whole with a set of parallel lines. In that configuration it is hard to discriminate if the lines are spiral or concentric. You might also try creating an angled jpeg pattern and painting the repeating pattern on the inside of a tube. The reason this would work well is that the inside of a tube can only be seen from a very narrow angle, so the fact that the pattern is flat would not be apparent in the final work. Animation would not work, but for a static view I think it would save a lot of useless geometry.

Hi folks.
Look in Wikipedia for information about riffles. You will see smooth bore, polygonal bore (Boofredlay's tutorial) and riffled bore (see attached SU file).
The file is a bit large, sorry.

Thanks Jean, that really is a good way of achieving that effect.

Jean, that last scene scared me
-
Jean and everbody else..Thanks for your time and work..Lots of good info..

Your welcome, and I think we had more fun than you did.

Hi folks.
Of course it is fun, otherwise, I would not be doing these tutorials.
