Here are the steps to make a hollow tube in Roblox Studio:
1. Make a cylinder the size of the tube you want
2. Make another cylinder the size of the hole you want through the cylinder. To ensure accuracy, make it a little longer than the first cylinder
3. Position the second cylinder inside the first cylinder
4. Right-click the second cylinder and select “Negate”
5. Select both cylinders, right-click on them, and select “Union”
NOTES: Once you union something, if you resize it it will resize all sides at once. To make it longer, duplicate the original tube and move it over to make it as long as you want and then union them together. To make it shorter, make a part that covers the part of the tube you want to remove, negate it, and then union the part and the tube together.
