Hi Mike,
Thank you for your prompt reply. I took your suggestion and posted my
question to sci.math and received a response from Clive. His questions
and my responses are at the bottom of this post.
My response to Clive from sci.math:
Hi Clive,
Thank you for your prompt reply and questions. I'll see if I can
make more sense out of my original question by answering yours:
1) Is this essentially a 2dimensional problem? That is, are all the
cuts perpendicular to the two 4'x4' faces of a foam block?
No...we are cutting tapered sheets of (styro)foam insulation to match
the pitch of a roof, to be laid beneath the shingles.
2) What is the definition of a Board Foot?
A unit of cubic measure for material, equal to one foot square by one
inch thick, i.e. the VOLUME of that piece of material. A piece of
material with the dimensions 1" x 4' x 8' = 32 board feet.
3) How complex are the shapes that you are trying to produce?
 Can you say what these shapes are? Please see #1 answer.
 What is meant by "Tapered Foam Cuts"? Front face of sheet may be .5
"  Back face may be 2".

 How are the shapes defined? If you loook at the end product from the
side it will look like a triangle or tapered rectangle.
 Are any of the faces curved? No.
 What is the maximum number of faces that a shape might have? 6 
Front, back, top, bottom & two sides.
4) Can you say more about what a wire set is? We cut the block of
foam with hot wires. A wire set is the setting for the wires to cut
one block, yielding X number of different angled sheets.
5) Is there a web site all about this? Sorry, the website has no
pictures of this product, these are a special order product that vary
in dinensions. Just think of a triangle with volume.
Thank you again,
Dave
