IDEA provides a Manual alignment tool that uses some directions given by the user. The procedure

undesired parts of data. This tool allows to globally and simultaneously optimize the position of a set of
scans. Finally, the Datum alignment tool allows, once finished the generation and consequent editing of
a mesh, to modify its position in the global reference system.
2.2.3.1 Manual alignment
The Manual alignment tool tool allows to face and solve even the most difficult alignment issues, asking
