Spring,
it seems to me like there are various errors in editing shapefiles in QGIS 2.10 and 2.12. Some weeks ago, I reported an error that does not allow for proper feature deleting. The shapes I deleted were gone in QGIS, but they were still present in ArcMap. Matthias Kuhn wrote in this context: Hi I just received a confirmation that Marco is working on a fix for this issue and targets the 2.14 release. GDAL 2.0 would still be nice to also have the geometry issue fixed :) Best regards -- Matthias Kuhn If it turns out that your problems come from the same origin, maybe it’s time now to disable shapefile editing in QGIS until those problems are solved. Maybe someone more competent than me can give information to the list on the troubleshooting status? QGIS is such an outstanding piece of software, we’d love to see that errors disappear!

I can check off most of those items except upgrading. This is new development so likely computer based? Rather than QGIS. I'll look at the bug reports; this is a pretty serious error. Thank you . . . . . . Cheers . . . . .

I would upgrade to the latest version. Then to figure out where the problem is, I would: Make sure that both layer are polygon layers (and not lines and polygons), that both have the same CRS (along with the project CRS), that both have the same fields and that the "receiving layer" is in editing mode, and saved subsequently. I would limited the amount of open files and open plugins. Try copying polygons from a newly created file to an empty newly created layer in QGIS and not a shapefile that was previously manipulated in other softwares. All this could help you find the source of the problem. I would also look at the bug reports to see if it is an issue for that version. Hope this helps. Nicolas Cadieux M.Sc.

I am attempting to create simple polygons in a shapefile by direct vertex entry or copying polygons from another shapefile layer and pasting them into the active layer. In almost every case, these features disappear. There is an entity entry in the attribute table but there are no polygons created. In one case a polygon was created but it was not the shape that I digitized; no more polygons could be created although the process for doing so appears to be working. No error messages were created. The CRS for the project and the shapefile are the same. The shapefile can be opened in another GIS but has no content. Here are some product details: QGIS version 2.10.1-Pisa QGIS code revision d20c5b7 <https://github.com/qgis/QGIS/commit/d20c5b7> Thanks very much for any help you can render, Cheers . . . . . . . .
