Android app for Plywood optimization -- 3

I need a simple Android app to optimize the number of ply sheets required to get the selected number and sizes of ply pieces. I will explain in 3 Parts Part 1 - I need a plywood optimisation app where I enter plywood piece sizes and it optimised it to show how many plywood sheets (2440mm x 1220mm) I need. This is the simple logic of the app. Refer:- [login to view URL] Part 2 - instead of entering plywood pieces each time manually. I need it setup already in the database list of plywoods pieces sizes where I can easily choose and add quantity and then optimise it Part 3 - Instead of selecting ply pieces from a long list of already set up ply piece sizes. Change it to a group of ply pieces like a box where each box needs 2 Side Pieces, Top and Bottom Piece, Back Piece and Door Piece in front. I need this box in different sizes as a selection in a menu. ( I will give different sizes) When Selected all ply pieces that are needed to make the box it selected and optimizes with an output of the number of sheets required to make all the boxes selected. Please bid only if read my description and you are interested.
