Here is what looks like a great tool for people building stuff in Second Life, I say looks because I haven’t tried it out yet, and I don’t remember where I read about it to send you to a proper review. Here is a quote from the site.

Rokuro Pro displays Scrupted Prim and texture of second life, before they are upload.
And a sculpted Prim can be edited in the three modes(ROKURO/TOKOROTEN/MAGE).The three modes can be combined and used. Furthermore, Rokuro Pro can correct a coordinate for every control point(Bitmap mode).
Rokuro mode makes a solid of revolution. Tokoroten mode makes a pushed-out object.
MAGE mode makes the form where the pipe was bent. Mage mode can make a neon tube and an accessory easily.
Caution: It is not guaranteed that a display of AGARI is completely the same as a display of Scrupted Prim in a second life. Source: ROKURO Pro -Scrupted Prim Previewer and Editor
