about Three-point Alignment mode, you may refer to the Three-point Alignment

Once a file is saved, the point filters are saved with it and cannot be
changed or removed.
Manual Alignment
Sometimes it is necessary to manually manipulate (position) two segments into
alignment for registration.
►
To perform manual alignment:
1
Manipulate the selected segment (Blue) using the Ctrl button and the mouse
to roughly align it with the reference frame. The Shift button moves the
selected segment (Yellow) and the Ctrl button moves the reference segment
(Blue).
When Ctrl is pressed, transformation is performed only on the selected
segment. Mouse-manipulation controls operate as follows:
Rotate the segment by holding down the left mouse button while
moving it over the scene.
Move/pan segments in the scene by holding down both mouse
buttons and moving the mouse.
Zoom in/out by clicking the right mouse button while moving the
mouse or with the mouse wheel.
