Ah ! I have made that with a curve and a solid and not with 2 curves !

Yes, the solid as an input doesn't work with history right now, because that original solid gets deleted.

But with 2 curves none of the inputs are deleted - this is the case that works with history right now.

This is a very cool trick. I have so much to learn about nurbs...

Hi Joe, that is not about mystery of NURBS, but rather about Michael's astonishing skills! -Petr

Some quick notes...

-Now, when comming boolean curves, it proved to be very useful that Invert command works from within other running command like Trim or Boolean.

-Updated/fixed "gizmo" for rotating background image looks good and works fine.

-Thanks for implementing a way to turn off points by pushing Esc key. Priceless!

Trivial question but...

As the first choice for a boolean Intersection seems give different results :)
why with a same "first start"
order for choice of the "second set" give a same result!
Star / Circle / Polygon = Star / Polygon / Circle : is that normal?
Anxious rationalist :D

For intersection, multiple objects within a single set are first unioned together into a single object, and then those 2 unioned results are then intersected with each other.

Does that explain what you are seeing there?

For intersecting 3 objects in that way you may want to do that with 2 separate runs of the boolean intersection command, or possibly use merge mode instead.

Not posted the following so there

I have 3 objects, but in reality we can put any numbers of object for "the second set"!
So that I ask if the order of selection of objects has or has not importance for end intersection (first being selected) :)

I don't think it should make any difference.

The thing that makes a difference is what set you put the "extra" object in.

For instance if the 2 sets are ( 1 2 ) isect ( 3 ) or ( 1 ) iset ( 2 3 ), that can make a difference.
