Blender add-ons review — BoxCutter and Hard Ops - BlenderNation
Hard Ops makes use of Blender's modifiers and other built-in tools and functions. It does not have its own custom Booleans or other custom-coded algorithms. The advantage of this is that the non-destructive modifier-based output of Hard Ops is easily adjustable because you're already familiar with the native modifier settings.
