I have a question about the Geometry.DistanceTo node.
This node calculates the distance between two geometries. However, I do not know where this distance is calculated from.
For example, is it from the surface of each geometry, from the center of gravity, or something else?
I would like to know how this distance is calculated and what the value is.
I think this is measured from the outsermost point of the elements. And measures to the closest point between them.

Yes, at least what I have found out
Here is two polylines in Civil 3D
And it does the same with these two circles
Interesting is that when I tested distance between a 3D polyline and a 2D Polyline I actually got 3D distance

@patrick.ericson is correct.
Given two geometrys called A and B, this node basically:
- Finds the closest point on A to B.
- Finds the closest point on B to A.
- Gets the distances from the point on A to the point on B.
The specifics of the method aren’t that (nor are they published), but it serves the purpose of understanding well enough. You can build a generic representation thereof using the Geometry.ClosestPointTo node.
Note that geometry A and B can be any valid non-mesh physical geometry; you can use a Point, Curve, Surface or Solid as either input.

Thank you all for the information.
