This dialog is compliant with Revision B of the IPC standard 7351 - Generic Requirements for Surface Mount Design and Land Pattern Standard. IPC-7351B was released in 2010 and supersedes IPC-7351A (which was released in 2007).
The IPC® Footprints Batch generator dialog is accessed by clicking Tools » IPC Compliant Footprints Batch generator from a PCB Library file (*.PcbLib).
The dialog can only be accessed if the IPC Footprint Generator extension is installed as part of your Altium NEXUS installation. This extension is installed by default, but if it is inadvertently uninstalled, the extension can be found on the Purchased tab of the Extensions & Updates page.
Hover over the icon and click to download the extension. Altium NEXUS must be restarted to complete installation.
If at any time you want to uninstall the extension, find the extension on the Installed tab of the Extensions & Updates page and click the icon to uninstall. Altium NEXUS must be restarted to complete the uninstall process.

Model Folder - use the browse button to search for and choose the location of the desired model.
Generate all footprints in - enable to generate all footprints in the current PCB Library.
Generate single PcbLib files per input file - check to generate a PCB Library file in the output folder with the same name as the input file being processed. The footprints from this file will be added to the PCB Library.
Generate single PcbLib files per footprint name - check to generate a PCB Library file in the output folder for every package in the input files.
Generate report on completion - check to generate a report upon completion.
Open generated report - check to open the generated report. This option is only available if Generate report on completion is checked.
Where pad trimming is applied, a warning is displayed in the generated report.
Open generated PcbLib files on completion - check to open the generated PCB Library files upon completion. This option is only accessible if Generate single PcbLib files per input file is checked.
Processing - an incremental bar that shows the progress of the batch generation process.
Start/Stop - click Start to launch the batch generation. Once the Start button is used, it then changes to Stop; click Stop to stop the batch process.
Close - click to stop the batch process and close the dialog.
Paste masks are split into small fills for packages with a large thermal pad (sized 2.1mm x 1.6mm, or larger).
For packages involving gullwing leads, pads are trimmed to prevent them from otherwise extending under the package's body.
For small packages having a large central thermal pad (PQFP, QFN, SOIC, and SOP), the peripheral pads are trimmed to ensure required clearance between the pads in accordance with the IPC Standard.
IPC footprints are always generated in metric units.
