 BOSL2 provides two different methods for rounding the edges of these cube-like primitives.
 
-* **Built-in Rounding** - [Cuboid()](https://github.com/BelfrySCAD/BOSL2/wiki/shapes3d.scad#module-cuboid), [prismoid()](https://github.com/BelfrySCAD/BOSL2/wiki/shapes3d.scad#functionmodule-prismoid), and [rounded_prism()](https://github.com/BelfrySCAD/BOSL2/wiki/rounding.scad#functionmodule-rounded_prism) all have built-in arguments for rounding some or all of their edges.

 * **Masking** -  BOSL2 includes a number of options for masking the edges and corners of objects. Masking can accomplish rounding tasks that are not possible with the built-in rounding arguments. For example with masking you can have a cube with a different rounding radius on the top edges than the rounding radius on the bottom edges.

 You can fillet top or bottom edges by using negative rounding values. Note that you cannot use negative rounding values on Z-aligned (side) edges.  If you need to add a fillet on a Z-aligned edge, use [fillet()](https://github.com/BelfrySCAD/BOSL2/wiki/shapes3d.scad#module-fillet):

 The [prismoid()](https://github.com/BelfrySCAD/BOSL2/wiki/shapes3d.scad#functionmodule-prismoid) differs from the cuboid and cube in that you can only round or chamfer the vertical(ish) edges using the built-in parameters. For those edges, you can specify rounding and/or chamfering for top and bottom separately:

 One limitation of using rounding arguments in [cuboid()](https://github.com/BelfrySCAD/BOSL2/wiki/shapes3d.scad#module-cuboid) is that all the rounded edges must have the same rounding radius.  Using masking we have the flexibility to apply different edge treatments to the same cube.  Masking can also be used on the [cube()](https://github.com/BelfrySCAD/BOSL2/wiki/shapes3d.scad#functionmodule-cube) and [prismoid()](https://github.com/BelfrySCAD/BOSL2/wiki/shapes3d.scad#functionmodule-prismoid) shapes.

In this tutorial we're concentrating on rounding cubes, but [rounded_prism()](https://github.com/BelfrySCAD/BOSL2/wiki/rounding.scad#functionmodule-rounded_prism) has capabilities that extend well beyond cube-like objects.

 A feature unique to [rounded_prism()](https://github.com/BelfrySCAD/BOSL2/wiki/rounding.scad#functionmodule-rounded_prism) is that it uses continuous curvature rounding. Rather than using constant radius arcs, continuous curvature rounding uses 4th-order Bezier curves. For complete details on how this works see [Types of Roundovers](https://github.com/BelfrySCAD/BOSL2/wiki/rounding.scad#section-types-of-roundovers).
