## 3D Plane Alignment |

Consists in the calculation of the of the survey points quota from the average plane. For example, we know that it is a surveyed plane( horizontal or inclined),and this function allows you to graphically verify the possible imperfect measurement. In the 3D preview window displayed in the calculated plane, the split in blue highlights the positive quote and the red one highlights the negative quote. At the end of the process, the program ask if you would like to save the results on the current survey. This option should allow, a once duplicate of the original survey., to compare the differences between the due numerical models( with the Compare measurements), to calculate the excavation and report( use the intersection function between the two DTM)

Algorithm use:

- Least squares;

- best fit plane check.
