If any features are loaded, the Attributes/ Style Functions submenu will contain an option to Copy Attributes Between Features. Selecting this option will display a dialog to copy attributes from features to other features(i.e. loaded or selected areas, lines or points).
Copy Attributes From— specify the features that contain attributes that will be copied. This may be all features or selected features based on the geometry type (points, lines, areas).
Copy Attributes To — Specify the features to gain the new attributes based on the spatial relationship to the features specified above.
Select the names of the attributes that will be copied. Use the Check All and Uncheck All buttons to quickly clear or select the full list.
This section will be enabled when multiple features in the Copy Attributes From selection may match features in the Copy Attributes To section. This is based on the geometry type, for example an area may contain many points, so copying from point features to area features will require a Multiple Feature Handling setting.
The attributes values from each matching "from" feature will be copied to the "to" attributes as a comma separated list.
If multiple from features are found, no attributes will be copied to the to features.
If multiple from features are found, attributes for the closest matching "from" feature will be copied to the "to" feature.
When copying attributes from point feature to area features, this setting will create multiple (duplicate) area features with different attributes for each "from" point.
