Favourite Mlab option

[Hank]

Hi there,

I was just thinking if we can make some contest and choose 3 favourite Mlab options in...
Let me start with:

1. Tubes from paths - this is 'must be' option for everyone who wants to create stuff like engines or shoelace. I wish you good luck working without it...
2. Boleans operation - mostly used when creating some frame. Joining pipes/tubes/cylinders is time-consuming. But with this option you do it much faster.
3. move: arrangements (Object -> lots more) For Blender users it's known as Array. Helpful and irreplaceable for all 'copy and move' objects like: fence or tire tread

And what's you favourite option?

BR, Hank
