Haven't had a chance to experiment with this yet but I have a need for a thin walled cylinder. I can build a cylinder, increase the hole size to the maximum, but I need a bit more. Are there any tricks for making the hole size closer to the size of the outside diameter.
Thanks in advance,
Tex in Texas

From: Tex Nasworthy Are there any tricks for making the hole size closer to the size of the outside diameter. Here is a technique (copied/pasted from an older thread) for making hollow cylinders that are paper-thin. It can be used for other prim types too. From: Emily Lang
-Create a prim, e.g., a cylinder. Shift+drag to copy it.
-Go to the original cylinder. Texture its outer side with any texture and its top and bottom sides with 100% alphas.
-Go to the second cylinder. Hollow it, then texture its inner side with any texture, and its outer, top, and bottom sides with 100% alphas.
-Ctrl+Z on the second cylinder. It will snap back to the position of the original. What you have now in essense is a cylinder object with outer and inner sides and some empty space in between (the amount of empty space is dependent upon the hollow percentage that you used).
-Select the second cylinder and, using either math or a good eye, stretch it along the x- and y-axes until its inner side meets the original cylinder's outer side.

There isn't a way to increase it about 95% as far as I know, but you can try this... Make two hollowed out concentric cylinders. Apply full alpha textures to all but the inside of one and the outside of the other. Then adjust the diameters so the inside and outside almost match (the outside bing slightly bigger). Might not work for what you're doing and would cause problems if the visible texture had an alpha channel, but it never hurts to experiment. Edit: yeah... what she said  |

Thanks for the ideas, with a little scratching my head, or a little searching, I should have been able to come up with an answer on my own. But with all the folks willing to help out on this forum, it's hard not to be lazy. Thanks again, Tex |

Never tried it, but I've been wondering if it would be possible to script a bigger hole. Kinda like how it's possible to script an object beyond 90% alpha, I have a hunch it might be possible to script a hole beyond 95% as well. So make object, run script, remove script, pick up object and store it in your inventory for later use.
Should this work, then just remember that you can't size down objects once their thinckness reaches 0.001, so I bet sizing down such an extremely hollow object, making the wall even thinner could be problematic as well.

Use a tube prim. Give it as large of a hole as possible and then profile cut it to make a very thin cylinder. The bottom will be an edge unless you hollow the prim out a little.
