[Qgis-user] Simple Vector-Editing Question - Deleting Multiple Rings at Once

[Michael Treglia]

Hi Delaz, Nicholas,

Thanks so much for the responses!

Delaz - your solution works - not sure if it's quicker/simpler to click on
the rings using the 'delete ring' tool, but it's a smart alternative option.

Nicholas - I think the challenge is that you can select the objects, but I
couldn't figure out a way to select rings for a bulk deletion, as it's more
about removing the holes (and selecting the bounding vertices) than
selecting the objects themselves. I'm happy to learn if I was just missing
something.

On a related note - for the Shape Digitizing toolbar, those tools only work
to create new polygons, not new parts of a multipolygon, correct? Or is
there a way to do that I've been missing? (I know you can merge tool in
this case as well, but figured I'd check).

Thanks!
Mike
