Subtract one body from another

Subtract cuts one solid out of another: a cylinder through a block leaves a hole, a box across an edge leaves a notch.

Good to know

  • The order matters: the first solid you click is the one that is kept and cut, the second is the one taken away.
  • Union joins two solids into one, Intersect keeps only their common volume, and Split breaks two solids into their parts.

ModelingMove (and copy) a bodyMove slides the selected bodies from one point to another, by a pointer gesture or an exact typed distance. Switch on Copy and it leaves the original where it was and places a copy instead. FeaturesHollow a solid with ShellShell hollows a solid out to an even wall thickness, leaving open the faces you pick — a box becomes a tray, a block becomes a casing.
