Compare Mode Functionality

  • Editing the base map from diff view

    • Most of the edit operations are supported under the diff view. Any edits performed in diff view will assume you are editing the difference values and not the base values. The base values will get adjusted accordingly in the base file.

      • Add/Subtract/Multiply/Edit/Paste/Undo are all supported.

    • Zeroing out a table in diff view will make the comparison table data match the base table data.

  • Note: Live tracing is not supported while Map Compare mode is active.

Unsaved Table Change Indicator (Bold / Unbold) 

  • Tables with unsaved changes will cause the related table(s) and associated folder(s) names to bold. Saving or reverting the changes will result in the table(s)/folder(s) becoming unbold again.
