Does exist a plug that draw something selected at intersections?
(I have missed one :D

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.

Very cool!

Excellent!

I suppose since you were looking into adding the ability to add a style to a point that would then have it be available with "Types" also in the scene browser?

There is no "point" in the browser but you can invert selection by Plugin
so some tricky selection can be made :)
