The sheets hv 60" by 100'
The pieces hv rectangular/square shapes in several dims.

I need !!

Yes.
This is for my final project (Well, I will put on project if I can solve it !)
No.
This is based on a true company problem.

What to use depends on the parameters for the problem.

Are the pieces rectangular?  If so, are you cutting along the full length/breadth of the sheet (ie cut into striup, then cut the strips into smaller pieces etc)?  Or is this arbitrary placing of pieces (a bit like a jigsaw puzzle)?

If it is strips, then look at shelf packing algorithms (first fit, best-fit etc).

If not, there are lots of algorithms around (not so much code).

I'll see what I can put here for you.
