Looking for scripts

[Bones]

Can somebody tell me is there a script like loft and sweep or bend. I know that working in sketchup means working with basic type of modeling ( low poly), and most cases i can work without this scripts, but still will be faster with thouse scripts.

Lofting: closest thing is the "skin" ruby. I'm not sure what the other functions you mention do exactly.

"loft" it i somthing like extruding different shapes of profiles by patch. "Bend" - for example - you got cone and you need to bend it around a circle or some patch . Bassicly I'm looking for a scripts to model a complex forms fast. Usualy I'm modeling this things from scratch and result is ok, but to get correct form in sketchup this things takes lot of time!
