Possibility to change the X,Y, Z coordinates and rotation of the origin by value in a dialog box.
This way you can place the origin to a location where there are no points. For Example right underneath the scanner where the survey marker is placed.
Now I am only able to change the origin by selecting a point.
After you changed the location of the Origin by selecting a point you want to move the origin a bit.
For example when the Z = 183 you want to move it to Z = 0
and when you want to just rotate the origin a bit you can use the arrow buttons to adjust the angle a bit.
suggestion for UI:
