When can we see a plugin like AD shape modeling?

I would like to use V6 even V7 because it is much faster than V5 but there are some useful functions stopping me !
just like blend curve ,we can see the green line(ADSM) is more uniform than red (rhino default).

There are many powerful functions like flange\surface blend\surface matching,and the analysis tools ,the tools really can save our time on industrial data work !

If there is any tool can do this on V6 or V7,i will be glad to say R.I.P to AD shape modeling .
