Hi Pilou, try selecting all the curves and running Construct / Curve / Isect to generate point objects at all the intersections.

Then use the CopyToPoints command that Petr made:

The first stages of that CopyToPoints command is similar to the regular Transform/Copy, that you select objects to copy and then a base point on the object. But then you select point objects as the target locations rather than clicking, so select the points that were made in the intersect command for that stage.
