Frenchy,

Non-Destructive has been along for awhile. Long before Speedflow and even Hard Ops. I was using it in September on client projects with Jerry's help (masterxeon1001).

Wazou has done a nice job integrating his complex tool into a workflow-- just has Jerry has with Hard Ops and Boxcutter. The problem I see is that neither of them go far enough and it's important to *UNDERSTAND* what's behind all the fancy pie menus and commands. They even use vernacular not common to Blender.

My goal is to use NO ADDONS and teach people the power of all the modifiers w/regard to Non-Destructive modeling. Once you fully understand, you can decide if an accelerator toolkit, likd Speedflow, Fluent, Hard Ops and/or Boxcutter can help you. And if they break, you'll then know how to fix.

I would challenge all of them to try to create Vitaly's model in their tools. I doubt very seriously they can.
