Closing a Curve with the help of another Curve

Hi there,

I am busy modeling a large urban plan in Rhino, and the files that I have contains allot of open curves which I need to close. I remember that a while ago I used a function similar to that of Live paint in Illustrator, I cant however remember the command. The command would use the intersection from two curves to create a new curve. I have attached a screenshot which I hope clarifies what I mean. I know that I could trim and then rejoin the lines, but I would much rather do this in one command.

Can anyone help me?

It seems like something where the fillet command would be in order, just set the radius to 0 and select the lines you’d like to terminate into each other

Are you looking for CurveBoolean command?
