Activate the Align scan project function
Function “Align scan”
Now, the first point of the line has to be determined as origin of the new coordinate system. Set this new origin by clicking the left mouse button directly in Top-View.
Determine the first point of the line
In PointCab, the x axis appears which shows the direction visually. By defining a further point, the direction is aligned. The alignment is created by a defined direction of the arrow and uses the initially defined point as a basis.
Determine the direction by means of a second point
Of course, you can enter the coordinates manually in the Job Editor.
Edit transformation parameters
If you select Apply to user coordinate system (UCS) in Job Editor, the point clouds are only visually transformed into the user coordinate system. The original coordinates remain. If you close the PointCab project and reopen it, the transformation has disappeared.
Apply to user coordinate system
If you select Apply to project, a coordinate transformation is performed on the point cloud. The original coordinates are transformed in full into the new coordinate system. All three standard views have to be recalculated. After the calculation, your project is aligned to the previously defined line.
Scan data is aligned anew – Default views have to be updated anew
