AutoNest Batch Nesting




At times you may like to nest a series of tasks overnight or during a break. This facility is provided via the BatchNesting command. But to view the already nested layouts, select the ViewNEST command if you are working in AutoCAD. In Nest Manager, just open each of the nested results saved in .DXF files from the ‘Task Directory’ using a CAD or a DXF Viewer.


If the “Include Sub-Folders” check-box is marked, BatchNesting is able to find and nest Tasks (.JOB) residing on sub-folders.


Select the BatchNesting command from the icon or pulldown menu. The following dialog box will appear:




Each dialog box input option is described in the following:


Parts Directory

Display the default part directory as set in the Sysdata.

Task Directory

Display the default task directory as set in the Sysdata.

Include Sub-Folders

When this check-box is marked, all the task files residing on all the subfolders of the specified Task Directory will be displayed onto the “Available Tasks” list box.

For example :

Parts Directory : E:\TestData\AutoNEST-QA-Testing\Others

Task Directory : E:\TestData\AutoNEST-QA-Testing\Others


All task files (.JOB) residing on subfolders, to a maximum of two levels from ….\Others  will be displayed for selection.



There are 2 check-boxes:-

q   Normal

q   Remnant



Normal’ tasks refer to all the task files (*.job) created by the user.

Remnant’ tasks refer to tasks files (*.job) with the reserved suffix, ‘_$REM’ . For example : sample_$REM.job. These tasks are automatically created if the “Save Remnant” check-box in the Nesting Options of TaskEdit  is marked.

For more details, refer to TaskEdit.


By default, the ‘Extended’ check-box is un-marked which means that the nesting will run its usual course, producing the nested result within a very reasonable time.

If the ‘Extended’ check-box is marked, then the nesting time is going to be longer as the nesting algorithms will run through an additional set of routines, compare with the original and then display the better of the two results.

By running the Extended nesting, you will get either the SAME or BETTER nested results than if you were to run without marking the check-box. But there is a trade-off, Extended nesting will take significantly longer time to run.


Mark the ‘Auto-Bridge’ check-box if you wish to include bridging into the nested layouts. AutoBridge will follow the Bridge specifications as defined in TaskEdit.

Available Tasks

Display a list of tasks ( .JOB ) files found in the task directory. You can select one or more files to be nested by highlighting the file names and then click the BatchTable3 button. Click the BatchTable4 button to select ALL the files.


Selected Tasks

Display a list of task files selected to be nested. Click the BatchTable5 button to un-select the file(s) or click BatchTable6 to un-select ALL the files in the list box.


You can click the BatchTable_Start button to start the nesting process.

Alert Upon Nesting Completion

When this check-box is marked and when the batch nesting process is completed, BatchNesting will play the Windows default sound three times to alert the user (provided the speakers are correctly connected to the computer and turned-on).

Nested Tasks

Display a list of successfully nested task files. Click the BatchTable2   button to see if there is any error message.


Internally, once a task has been successfully nested, output files will be created. These files have the same name as the task but different file extensions as shown below.

Example : Task name is SAMPLE

Output Files:   SAMPLE.SYM






The .SYM file contains the results of the nesting in terms of each part and its location in the layout.


The .SUM file contains the nesting summary report in TEXT format.


The .XLS  file contains the nesting summary in Excel format.


The two .XML files contain the same information as .SYM and .SUM but written in extensible markup language (XML).


Upon completion of the nesting, the dialog box below will be displayed:


Batch_Complete1   Batch_Complete2


In AutoCAD, when the nesting has completed, you may use the ViewNEST command to view the nested results or open each of the nested layout (DXF files) from the Task directory.


In Nest Manager, upon the completion of the nesting, you can open the nested layout (DXF file) from the Task directory using a CAD or a DXF Viewer. To view the report of each of the nested results, click the “View .SUM Report” button.

Notes on Nested Layouts

1.The display of the nested results will be determined by the settings in “Nested Layout – Presentation” and “Nested Layout – Layer / Color Setting” of Sysdata.


2.You can choose to display the parts in their original layers /colors by selecting “DXF” or “DWG” in “File Format” of Sysdata.


3.Conversely you can choose to display the parts in “VEC” File Format where you can determine the layers /colors of:
External or outer profile of the Part
Internal or inner profile of the Part


Go to Sysdata settings for more details.
