Generate complex lines with points

You can use the LineBuilder to create the straight line segments and the 2DArcReplacer to create the arc segments.

Finally, assemble the arcs and the straights using the PathBuilder.

Thank you @david_r but how can I use the transformer 2DArcReplacer in this case ? The arc must be snap to the points and I think this transformer generate random curves no ?

I don't think there's anything random about the curve that is generated, you can specify all the curve parameters in the 2DArcReplacer. If you need the curve starting point to snap to the input point geometry, you could use the Offsetter to move the resulting curve.

 

If you need a more specific answer, it would help if you could post a sample point with curve parameters here.

Finally, what I need is ArcEstimator but for more than 3 points :-)

Sounds like you need a spline interpolator.

Maybe you can find some inspiration here: https://knowledge.safe.com/questions/2706/create-cubic-bezier-curves.html

Thank you very much @david_r. This link is exceptionnal because @takashi ask a question :-)

True!
