In the beginning (good start for a book!) LL created the sculptie and it was supposed to be (rough phrase here) a close approximation of an organic shape.
Apple, Orange, Banana (classics) but generally a sphere that's been pulled and pushed about a bit to give a general (not too precise) approximation of the original shape.
Cool, can handle that

Then I read that, soon after, due to some pressure/requests the sculptie (I'll use the work code even thought it's probably the wrong term) was tweaked to allow for the creation/display of more sharp/hard edged subjects.
Now, most (if not all) Sculptie guides pretty much cover the "let's push and pull a balloon about" method, which is great.
But as soon as you mention "Sharp" / "Crisp" / "Straight" The sky darkens, mysterious odd shaped clouds move in, and you think oh shit, I never should have spoken those words, I have made the gods angry !!!!!
I never get the feeling that someone asked how and you get a flood of answers back saying "yeah, sure, no problem, here's how you do it"
It all seems to be more. Voodoo Dolls, Naked Virgins and Goat Sacrifices than a normal simple answer.
Not sure why.
Either A: It's bloody hard to do or B: those who know how don't want to tell others, or C: Something else.
So, I'll ask (and duck under the sofa to avoid the wrath of satan for asking again the question)
How do you make a sharp sculptie.
Say using Maya as this seems to be a very preferred choice for such things.
A Box
A Steel Girder (simple extruded shape)
A set of steps
More advance: A Chair with say 4 legs, a seat and a back
I know they can be all done as I've seen them.
Together with window frames with many straight cross beams in the frame and much much more.
