Flags

Flag	Takes	Default	Meaning

`-pull`	direction	`the direction of each body that leaves the least undercut`	the direction the tool opens along: x, y, z or three numbers such as 0,0,1
`-spacing`	length or number	`1% of the part's size`	about how far apart the points judged lie, such as 0.5 or 1%
