 In addition to the simple [roundover](https://github.com/BelfrySCAD/BOSL2/wiki/masks2d.scad#functionmodule-mask2d_roundover) mask, and the [teardrop](https://github.com/BelfrySCAD/BOSL2/wiki/masks2d.scad#functionmodule-mask2d_teardrop) mask, there are masks for [cove](https://github.com/BelfrySCAD/BOSL2/wiki/masks2d.scad#functionmodule-mask2d_cove), [chamfer](https://github.com/BelfrySCAD/BOSL2/wiki/masks2d.scad#functionmodule-mask2d_chamfer), [rabbet](https://github.com/BelfrySCAD/BOSL2/wiki/masks2d.scad#functionmodule-mask2d_rabbet), [dovetail](https://github.com/BelfrySCAD/BOSL2/wiki/masks2d.scad#functionmodule-mask2d_dovetail) and [ogee](https://github.com/BelfrySCAD/BOSL2/wiki/masks2d.scad#functionmodule-mask2d_ogee) edges.
