AutoNest Nesting


The core nesting engine of AutoNEST is called NestPRO. The basic technology of NestPRO lies in its powerful nesting engine. NestPRO features an intelligence processor that auto-adapts to different nesting conditions such as stocks and parts of different size and quantity. NestPRO generates nested layouts that reduces material wastage and maximizes utilization.


From version 9.9 or higher, there are two additional nesting engines. They are called “Minimum Layouts” and “Minimum Layouts (Utilization)”. These new engines are designed to handle nesting jobs with high quantity.


Minimum Layouts” nesting engine was added to AutoNEST to cater for parts with high quantity. The objective is to achieve a nesting result with minimum nos. of layouts or high repeatability where materials are relatively inexpensive.  See page 71 for illustration


Minimum Layouts (Utilization)” is the latest nesting engine added to AutoNEST to improve the material utilization of the nesting results of “Minimum Layouts”.  It has dual objectives – to achieve high repeatability of the layouts (thus reducing the no. of different layouts) and to optimize the material usage (reducing no. of sheets used). See page 71 for illustration.


From version 12.2 or higher, a fourth nesting engine is added. It is called “Small-Part Control Nesting” or SPCN for short. SPCN is designed for cutting machines with un-uniform suction where certain area(s) are weak in suction and therefore not suited for small parts to be nested on those area(s). Before this nesting engine can be run, “Small-Part Zone(s) has to be defined on the stock size and the parts identified as “Small-Part” in the Task.


If you are unsure which engine to use – stick to the default which is NestPRO. NestPRO is able to nest most jobs efficiently with good results.


There are two commands for Nesting. Both commands generate nested layouts from tasks created by TaskEdit.  The first is for nesting one task at a time, and the second, for batch nesting of multiple tasks.




Nesting (Single Task)

To nest a single task, one at a time and then displays the nested result onto the current AutoCAD drawing session.



To nest a selection of tasks sequentially.  Nested results in .DXF format are created for each nested task for viewing at a later stage.

If you are running in the AutoCAD environment, use the ViewNEST command to view the nested layouts.
