●○○○ — Not much; I'm just letting you know about it.
Steps causing the bug to occur:
A suggestion for the documentation for Make Tube.
The documentation says "By default, the tube has a diameter and height of 1 and is centered at (0,0,0)." but it doesn't say how the tube is orientated. Easy to find out, but nice if it was explicit. I suggest something like "By default, the tube has a diameter and height of 1, it is centered at (0,0,0) and aligned along the y axis."
Have you been able to reproduce the problem?:
●●● — Yes, the problem occurs consistently when I follow the steps above
