Visualizza wikitesto di Calcolo di una caratteristica con algoritmo diverso

To '''calculate a feature with different algorithm''' it is not necessary to re-measure the feature itself, but it is possible to re-fit using the existing points.<br/>
This functionality is typically used to build a feature from an existing point cloud or recalculate an element using a different fitting algorithm.<br/>
This statement is manually written without user interface.<br/>
