How To Turn A Grid Polygon Into Single Polygon

LeviCecil

I have tessellated hexagon grid polygons that have multiple rows for each grid cell. I need to dissolve these into a single feature with all the grid lines intact that has the original grid cell count in a new field. When I try to dissolve, I just get the outline of the grids. I've tried adding a common ID field and dissolving on that, but no matter what, I get the outline. Is this possible with vector analysis? I'd like to avoid converting to raster if at all possible. I've encountered weird warping of lines when I try to go from polygon to raster and back again.

Yep, David is right. That's what I meant. Sorry I didn't explain further. It seems like a small negative buffer would work:

After the buffer and zoomed in:

When merged or dissolved, they end as a single non-contiguous multipart feature, which is I think what you want. Just experiment with the parameters until you get what you want.
