AutoNester-L automatically generates optimized markers on leather hides. The software nests the parts optimally in a very short time, minimizes waste and observes various specifications.
This image shows a data set from the furniture industry (upholstered furniture). Parts with these shapes should be cut out of the leather skin.
Time and cost savings
- Increases productivity
- Reduces material waste
- Takes into account various specifications
- Is competitive with experienced cutters
- Can be integrated into internal interfaces
Benefit & added value
AutoNester-L is a software package for automatic marker making on leather hides, widely used in the leather and automotive industries. For materials other than leather, we offer the AutoNester-T software.
AutoNester-L is capable of optimally nesting any quantity of parts in a very short time, minimizing waste, and following various specifications. The material utilization of the cross-sectional images obtained by AutoNester-L is competitive with the cross-sectional images obtained by experienced human patterners.

Layplan examples
The sectional views shown have been calculated by AutoNester-L. The specified runtimes refer to a standard PC. The colors in the parts and the hide indicate different levels of quality. Blue marks the best quality on the hide and the highest quality requirement on a part, followed by pink and red. Yellow stands for the lowest quality or the lowest quality requirement and black indicates defects on the leather hide. The parts must be placed on the hide in such a way that each region of a part that has a certain quality requirement lies on a region of the hide that has at least that quality level.
- Up to sixteen different quality levels
- Quality zones on the parts and the leather skin
- Consideration of holes in the dermis
- free rotation of the parts
- Nesting on several skins at the same time
Features of AutoNester-L
Methods
AutoNester-L combines current optimization techniques and latest research results to achieve the best results in the shortest time. We use local search techniques based on new variants of Simulated Annealing, multiple iterated greedy strategies paired with efficient heuristics, and fast, high-quality pattern recognition techniques.
In the local search procedures, we use fully dynamic and statistical methods for parameter setting to increase quality and speed. We use a combination of branch-and-bound algorithms and linear programming to calculate quality guarantees for the generated cross-sectional images.
Software & API
The AutoNester-L software package for the automatic creation of markers on leather hides and other quality materials can be used via an application programming interface (API). The software is aimed at developers of CAD systems for the leather processing industry and for other industries with compatible packaging problems. CAD system developers can easily integrate AutoNester-L into their own CAD software.
On request, we create custom software with an individual user interface for end users based on the AutoNester-L software core.
AutoNester-L is available for all Microsoft Windows PC operating systems.
