Creating mapping
A mapping can be created, selected, deleted and cleared. The Mapping option helps you to highlight the entities which are having the same usage.

If your drawing contains unclosed polylines that represent Spaces, Rent to units or Rent from units, then the outcome of area calculations, available workspace calculations and copying data from and to spaces might be incorrect. We recommend that your drawing contains only closed polylines.

You can reposition the legend using the Settings > Mapping > Legend insert point option.

When a mapping is applied, a new layer is created. Make sure not to draw on this layer since the data on this layer will be erased when a new mapping is applied.

If you apply mapping on a large number (in hundreds) of entities, it may take several minutes for the mapping to complete.
