I edited a shapefile of approximately 1500+ pipe segments yesterday in QGIS. When opened today (first in ArcMAP by another user) only about 10% of the pipes were drawn. The same happened when the shapefile was subsequently opened again in QGIS. The attribute table still shows the 1500+ pipes.
Any help as to why they are not drawing?
