Drawing solid pyramid

 From:  Ditto
Very basic question, I guess, but what is the best way to draw a solid pyramid? And, being here, how should I draw a truncated pyramid.

One could array inclined planes, or sweep a line around a polygon, or boolean parts away from a box. But if there is a cone and a cylinder, why isn't there a box and a pyramid?

I am asking because I see problems with filleting coming up again and again because of inappropriate construction methods, ie. it is correct at first, but gives headaches later.

Thanks in advance,


Edit: Never mind, I found a previous discussion about exactly the same question: http://moi3d.com/forum/messages.php?webtag=MOI&msg=3228.1

All set, thanks!
