WHAT IT DOES
Are you seeking a more efficient alternative to the laborious process of utilizing Blender's grid fill tool? Introducing Face Grid Fill, a swift solution that eliminates the need for deleting n-gon faces, selecting edges, and applying a grid fill. Simply select the desired face, employ the Face Grid Fill command, and voila, your task is complete. This innovative concept originated from a place of personal exasperation with the superfluous time-consuming steps involved. Interestingly, it appears that developers had been presented with this suggestion approximately four years ago, yet it remained unimplemented. Lacking any prior knowledge of Python, I turned to AI for assistance, and after several hours of dedicated work, success was achieved.

As a gesture of goodwill, I am offering this invaluable tool to the community for free. However, should you find value in this solution and wish to support its further development, any donations would be greatly appreciated.

HOW TO INSTAL
Download file -> Blender Edit -> Preferences.. -> Install -> Select file "FaceGridFill.py" -> Install Add-on -> Enable it

HOW IT WORKS
While in Edit mode select n-gon face you want to grid fill.

Face -> Face Grid Fill
or
CTRL + F -> Face Grid Fill

WARNING: It only works with even vertex count. The same as standard grid fill
