Pat,
To let other users know, we have communicated outside this discussion. You have sent me your personal geodatabase.
The reason why the Feature Class/Subtype drop-down is empty on the Find Dangles Check Properties dialog is because the 'finally' personal geodatabase topology does not have any feature classes specified. To resolve this issue, please do the following:
1. Open ArcCatalog and navigate to the location of the feature dataset that contains the 'finally' geodatabse topology.
2. Select the 'finally' topology object and right-click, select Properties... from the context menu. The Topology Properties dialog is launched.
3. On the Topology Properties dialog, click the Feature classes tab. You will see that no feature classes are listed. This is the reason why featurefor1918 does not appear on the Feature Class/Subtype drop-down on the Find Dangles Check Properties dialog.
4. On the Feature Class tab, click Add Class... and the Add Class dialog is launched.
5. On the Add Class dialog, choose featurefor1918.
6. On the Add Class dialog, click OK
7. On the Topology Properties dialog, click OK.
8. Open ArcMap and the 'finally' topology and the featurefor1918 feature class to your map.
9. Invoke the Find Dangles Check Properties dialog. Click the Feature Class/Subtype drop-down and the featurefor1918 feature class is present.
Regards,
Dan
