saw this in BA  not sure about it?? it only works on cylinders!

can see uses for that as a poser user........ but

grease pencil works with retoppo/bsurfaces (if I said that right)

so for me this looks like an easy way to do something I can do anyway?

guess it depends on how often/why I'd need it

 

from all the plugins/addons etc the only thing I have "learnt" is I really should learn python rofl ;-)
