Hi all,

Many hours now, that I try to "cut" / "split" in two a Catenary curve in 2 pieces.
I tried :

* with "curve/curve intersection" then shatter
* Rebuiding the curve then shatter.
* Intersection with a plane.
* trim

No result.
May I missing somthing?

Have a nice evening ! ( or day depend where you are around the world!)
Regards,
fred

Hi Kerem , hi Djordje!

Thanks you guys! Your both solution are working.
That's help me a lot !

For using trim fonction , I were missing that should be a closed volume , should have a '"inside" and a "outside"!!

have a nice day,
Fred
