Use free SU8 to convert back to SU6?

Pilou works with a Minitel.
( private joke for frenchies ) -
Ok now that work from the middle to the end of line!
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
PS My Minitel works like a charm

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.

Dat is *&^$@# genius!!
nice work gilles

Very clever gilles -- makes perfect sense and needs no math to execute
Best,
Jason. -
VERY clever Pilou !
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!

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

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?
-
Good try but...
-
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 -
TIG,
To me the problem is that d/2 should be measured perpendicular to the final edge, not the diagonal.

Exactly right - I was adding that to my last post as you posted...
The difference between offsetting the diagonal and the sides is the error.
