I have an AGX 1200 project with a series of boundary shapefiles in it. At the full extent of the shapefiles (all shapefiles have the same extent), I can see all the features of all of the shapefiles. However, when I zoom in, some of them disappear. Some shapefiles work at any zoom level, and some of them disappear when I zoom in. First just part of the features will disappear, like the right half of the extent. Then as I go in further, they disappear completely. None of them have any minimum/maximum display scales set. The ones that work, work consistently, and the ones that fail, fail consistently.
Can anyone help? Thanks in advance!
