I have a problem with cutting a circle by 2 tangent lines.


How can I join sections with the tangent part of the circle?

Hello
I think it could be better you read some complete tutorial on Grasshopper

There are many problems.
it is better you internalize the curve by right clicking on curve. It is more simple for helpers than posting a 3dm file.

Shatter doesn’t accept point but curve parameter.
To cut the cut the circle you must input a flatten list of tA. Because circle is on input A


Then could choose which part to keep using item. It is not very smart but work.

You could use arc that will give you the good part of curve.

It is not very clever but I hope you will learn a bit.
