# 3.9.7: Curve-Curve Intersection

This component takes two lists of curves as input: "**Intersecting**" curves and curves "**ToIntersect**". It tests which of the urves in "**ToIntersect**" get intersected by curves in "**Intersecting**". Output-plug **“Crvs”** delivers a list of poly curves which feature internal points at intersections. There is a one-to-one correspondence between the list of input lines in "**ToIntersect**" and the output curves of **“Crvs”**. The input-plug **“LDist”** sets the tolerance length in meter for finding intersections between curves that do not actually intersect. **“LDist”** is also the minimum length of segments at the ends of curves (e.g. at T-intersections). The component can deal with corner cases where intersecting line lie within lines to intersect or touch them (see fig. 3.9.7.1).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://manual.karamba3d.com/beta/3-in-depth-component-reference/3.8-utilities/3.8.7-line-line-intersection.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
