      Did you take the alignment point at the end of the line?

      The horizontal point of the end of the line don't work (on the right of the last red point on the blue line)

      OK that works only if you take the click point under your arrey drawing! Very curious!!! 😲
      Luck ? 😄

        Right - now I see that it infer from itself. But I get no snapping from the end-point.

            Use free SU8 to convert back to SU6?

                  The two #5 and the #4 absent were not modified ! 😉

                  Your method is very very tricky! 😎

                  I must find a solution with the offset tool 🤓

                      Gilles, you're a genius! I finally had a chance to get back to look at this and your method works very nicely. I wonder if I'll be able to remember it the next time I need it.

                                  Bravo to you too.

                                  Here's my slight reworking of your brilliant ideas, with some explanatory notes.
                                  I think this way is a little simpler and easier to see what's happening.

                                    Cool but there is a little mystery 😉
                                    In your file (from the mine modified) tichkness is not 1.000000m but 0.997509m
                                    CD = 1.320818 m
                                    Or you don't change the drawing and just type the text's explanations for only the theory?

                                    In a nurbs modeler with the Technic of circle (first example of Jeff video) (with of course sames measures)
                                    CD = 1.3239127 m & angle 40.945192°

                                    The adventure is not finished! 😄

                                      I Have no idea how you figured that out 😲 One snaps to a line that is not there until the execution. That's wild!

                                        In the example, why push pull up on the face? The whole point seems to be to find Point 'B'. (diagram THAT clause 😛 )

                                        Maybe this is beyond my maths. True: the center cut line in the first picture does describe the center of the final board, call it point 'X'. B is a right angle from 'X' but it's a right angle from the board's diagonal, not from the final axis of the board. Still it lies on the edge of the board a distance d/2 from point X?brace - 1.png

                                            Pilou's version appears to work...
                                            But when I reproduce it there's inaccuracy again 😕
                                            Logic [initially] says that offsetting [pushpulling] a face that is coplanar with the known diagonal by width/2 and then adding the new sloping lines through the points ought to make them along the rail's raking edges ???
                                            BUT the offset is perpendicular to the diagonal NOT the rails sides !
                                            Hence the errors... very much like all other approximation methods 😕
