An important class of nodes in Archimatix is called Mesher. Mesher nodes generate standard Unity meshes procedurally, usually starting with one or more shapes (or “spline”) inputs and combining them according to certain rules. For example, in an Extrude, the shape is copied and extruded  a certain distance, while triangles bridge between the two shapes.  Thus, for example, a cube is a mesh that is an extrusion of a square shape.

To experiment with a Mesher, instantiate the BevelBox from the 3D Object Library and manipulate its various handles to transform its output.
