Circle Intersection

Functionality

The node is designed to get the intersection between two co-planar circles in space. To define the containing plane it can accept a third point or the normal of the plane.

To work in 2D just set a normal vector of (0,0,1)

Inputs / Parameters

Param	Type	Description
Define Plane	Enum.	Determine method: input the plane’s normal or a third point in plane
Center A	Vertices	Center of the first circle
Radius A	Vertices	Radius of the first circle
Center B	Vertices	Center of the second circle
Radius B	Vertices	Radius of the second circle
Pt in plane	Vertices	Input point in working plane. It can’t be aligned with the centers
Normal	Vertices	Input normal of working plane. It can’t be (0,0,0)

Advanced Parameters

In the N-Panel (and on the right-click menu) you can use the toggle:

• Match List Global: Define how list with different lengths should be matched. Refers to the matching of level 1

• Match List Local: Define how list with different lengths should be matched. Refers to the matching of level 2

Outputs

• Intersect: Returns True if the circles intersect.

• Intersection A: Returns first intersection between the circles (Starting at left or top)

• Intersection B: Returns second intersection between the circles (Starting at left or top)
