API: How can I delete all breakline sets included in definition off Surface?

[joantopo]

I want delete all breakline sets of one selected surface using API.

There is "SurfaceOperationAddBreakline" but I don´t find "SurfaceOperationDeleteSetBreakline" for example.

Is there other way to delete all breakline sets of one surface?

Later, I want to create one set breakline for each layer which has been selected by user.

I know that I can use qselect, but I want do this process automatically.

Perhaps it is "SurfaceOperationCollection" method Remove or RemoveAt()

Let me know if you need any further help here.

Hi Partha.

 I haven´t seen that link before.It´s great!.

However,I don´understand "surfaceId". How I put Id surface to refer the surface?

Thank you.
