||1DCutX is the length cutting optimization add-in for Microsoft Excel. If finds how to cut one-dimensional (1D) linear stocks (bars, pipes, beams, wires, etc.) in order to minimize the material waste and the cost without leaving Microsoft Excel. It reads the spreadsheets, performs the optimization and generates the detailed report and the graphical layouts instantly within the same workbook. Any production or building company or even an individual handyman faces the common-known problem of cutting big linear stocks by smaller pieces. Microsoft Excel can keep track of the inventory of such stock and pieces, but it cannot figure out how to cut them. 1DCutX provides such functionality and turns Excel into powerful cutting optimization tool suitable for anyone who knows how to work with the spreadsheets. The major features of 1DCutX 1. No need to find, study and use any additional software. The user works with Microsoft Excel that now provides an additional functionality coming from the small add-in. 2. No mess with import/export/save/load any extra files - everything is stored within a workbook and it practically eliminates any errors due to incorrect import/export. 3. Simplicity and flexibility. The user can specify different information and get different scenarios of the optimizations. For example, if the stock quantity is not specified then 1DCutX assumes unlimited supply, otherwise it uses only specified amount of stocks. 4. Saw kerf (thickness) support. Cutting produces the gap between parts that shrinks the result part sizes by a saw thickness. 5. Control cut-offs (waste parts) size. Some cutting machines are unable to make a cut on tiny pieces, because of the technical restriction, like cutting several millimetres from the wood beam. 6. Incomplete optimization. In some cases the supply of the stocks is limited and all parts cannot be cut from them.
