Yes, I have noticed it. 
Also, I couldn't find similar spherify modifier.
I found useful tight, scale and twist operation.
Although, in the middle of the process I should have ticken the mesh before because I couldn't use it afterwards.
I think I'll will make another one.
Thank you for guidance.
Btw, I've posted in another thread about TopMod algorithm: Add Handle. Do you know how to create it in W3D?
