Electronic – Altium PCB design: Vias stitching problem

altiumdesign

I need to create a VIA stitching on my design but the option doesn't work:

I select the width of my VIA, the area where I want to place all of them, and the net to be connected.

At the end it displayed:

Unable to add any stitching vias to net GND_3

(GND_3 is the name of my ground plane)

I have 10 layers on my board. No tracks are passing under my area, and no components are placed.

note: It was working when no tracks were routed. So maybe the option has no place for the vias…

Thanks for reading and maybe helping.

EDIT 04.04.18:
The placment of the vias stitching is placed on the design but there are no via on it (always the same message "unable to add stitching via"). I have like 20 vias stitching area but with no via.

This happened to me and I finally figured it out! I had 3 GND planes I was looking to stitch and the via stitching tool would give me the same message. I had to shelve the larger polygons I had for power on an inner layer before the feature worked. Hope this helps for future reference.
