# Intersection between Edge and Plane

Hi,

is there is a way to get the intersection between a plane and an edge? Intersection between line and plane can be realized with intersection(...) function but I need the intersection between a plane and an edge.

Converting the edge to a line (with evEdgeTangentLine) won't work either since the line has an infinite length but I have to know whether there is an intersection within the finite edge length.

Constructing a huge face on the plane and intersect with that would work sometimes - but it will fail for very small angles between plane/long edge since the face is finite in its dimension.

Thank you,

Martin

6✭thank you for your fast reply. Unfortunately evDistance does not work with planes. From the docs:

side0: One of the following: A query, or a point (3D Length Vector), or a

`Line`

, or an array of points, or an array of`Line`

s.I also tried to call evDistance with something like

... "side0": plane(vector(0,0,0) * meter, vector(1,0,0)) ...

Of cause not with hardcoded vectors but some vectors calculated previously. But the documentation is right - this call fails. There is a workaround by creating a plane with opPlane, use that object in evDistance with the extendSide0/extendSide1 argument and delete the object afterwards. But this is ugly. Maybe someone could add a plane support in evDistance.

Thank you,

Martin

1,017✭✭✭✭6✭unfortunately intersection won't do the job. At least not without further processing to check whether the point is part of the edge or not. But I think I will continue with the workaround described above.

Best regards,
