Tutorial Post 11: Three-point Transformation.

Three-point transformation 'ABC' -> 'DEF' transforms selected endpoints by isometric transformation that transforms the point 'A'  to the point 'D', the half-line 'AB' to the half-line 'DE' and the plane 'ABC' to the plane 'DEF'.  Three-point transformation is available on the constructive methods sub-menu ('QM...').

Before you can apply the transformation you need to set six constructive points ('QPS...' - see Tutorial Post 5) and select the endpoints to be transformed ('QS...' - see Tutorial Post 4):

Then you can execute the transformation (i.e. by the key sequence 'QMT'):

Note that the selected point from point 'A' has been transformed to the point 'D' and the selected segment from 'AB' has been transformed on the line 'DE'.

On the following view from another perspective you can see that the selected points from the plane 'ABC' are transformed on the plane 'DEF'.
