Editing/Selection of features/Disapearing Features

[AndrewPihlaja]

Hi All
I am using ArcGIS10 Windows 7 on a 64-bit machine (more than passes the minimum requirements), with an ArcView license.
When I am editing in ArcMap, some of the features that I can clearly see on the screen are not selectable, even though they are set as selectable in the selectable layers. Just wondering why this is. All of our features are stored in feature datasets inside of a file geodatabase. It's funny because I have a building layer, symbolized based on a field in the attribute table, and I can only select one or two of the buildings, both when editing and not. One minute this happens, and the next, everything is alright.
Another problem that I have is features that are disappearing at certain scales. I do not have any reference scales set, they just are not there. Sometimes when I zoom out, they pop back up, right where they are supposed to be.
Another problem... When I export a map, everything looks good in the ArcMap window, but once the export is complete (to a jpeg), some features are missing.
I think everything is related somehow, but I'm not sure. Everything seems to be problematic with the layers being visible/selectable or not.
Any help would be appreciated.

I'm having this same problem. I'll spend hours digitizing features in a personal geodatabase feature class, save the edits, stop editing and they're gone when I look at it again. It's wasting so much time having to go back and now I'm wondering what else is missing. I'm using 9.3.1. It's so frustrating. I don't know what to do or how to stop it.

Has anyone found a solution to this problem? Are there any Esri staff monitoring this thread?

I've found that spatial indexes in the geodatabase become corrupt at seemingly random times.  The result is that features disappear in the data view, even though you can still see the attributes in the table, and even zoom to the feature from within the table.  Zooming the map way out usually makes the missing features re-appear.  My solution is to delete the spatial index either in ArcCatalog>Feature Properties>Indexes, or using the Remove Spatial Index tool in ArcToolbox.

This worked for me.

I am using 10 sp1 on a Windows 7 64-bit also.  My digitized features haven't disappeared (yet) but suddenly when I try to edit, I get no target layer selection.  It immediately pops open the create attributes window and I haven't chosen which layer I want to edit yet.  Worked fine until right now and seems to be defaulting to want to edit a layer I worked on earlier (annotation) because now I want to create points in a newly made personal gdb feature class and it is telling me my geometry is invalid.  Anyone else have this problem or know how to clear it to be able to chose my edit target layer again?  All layers coord sys match data frame and all extents match.

I was having a similar issue: When exporting a point feature class from ver10 mdb to ver9.3 mdb, and then viewing in 9.3, the points initially appeared. After zooming in, they disappeared. I tried this several times with the same result. My workaround was to (in ver10) export the point feature class to a SHP and then (in ver10) export that SHP back to the ver9.3 mdb....and it worked.

Hopefully, this will be a quick fix for ESRI.

I'm having the same issue - features are digitized at a certain scale - then when I zoom out they dissapear! 
I'm working with a personal geodatabase and Arc cannot delete the spatial index of a personal geodatabase (someone suggested this as a fix on the forum). 

Can anyone help!

If this issue occur in Shapefile, you may try deleting the spatial index from the Properties of the shapefile.

ArcCatalog > Shapefile properties > Indexes Tab > Spatial Index > Delete and then Add > Apply the changes

If this occurs in a File Geodatabase, you may try recalculating the spatial index from the Properties of the Feature class.

ArcCatalog > Feature class Properties > Indexes Tab > Spatial Index > Recalculate > Apply the changes
ArcCatalog > Feature class Properties > Indexes Tab > Spatial Index > Delete and Recalculate > Apply the changes

Unfortunately for a personal geodatabase feature classes, there is no button to recalculate the spatial index as in File GDB or Shapefile. However the Spatial Index can be recalculated by exporting the feature class again to the same geodatabase or to a different geodatabase.

ArcCatalog > Right-click on feature class > Export > To Geodatabase (single)
or
ArcToolbox > Conversion tools > To Geodatabase > Feature class to Feature Class

Hope this helps. If you further face any issues, I would recommend to contact Technical Support for further assistance.
