The Hotlink tool (the red lightning bolt) has undergone a major revision. No longer will the layer need to be chosen in the table-of-contents before clicking on a feature in the map. Now clicking in the map (or scene) will identify all of the features and populate a list in the Hotlink window. This should be more intuitive and bring the Hotlink tool in ArcGIS inline with the Hotlink tool in GOMsmart. It will also make available features in a single layer that may not be accessible in ArcMap because of overlapping data, such as certain sand-body reservoirs that stack vertically.
3-D Field View
All of the changes above apply to 3-D as well. ESA Tools are easy to access and the Hotlink tool is able to click through other features in ways that it has not been able to do before. And Field Views now load dynamically so that improvements can be made much more quickly than they had in the past.
