Computes the minimum distance between two paths.

Name Type Range Description
inPath1 Path First input path
inPath2 Path Second input path
inPathDistanceMode PathDistanceMode Distance measuring method
inResolution Real 0.0 -
outDistance Real Minimal distance between input paths
outConnectingSegment Segment2D Segment connecting input paths having minimal length


The operation finds the minimal distance between a characteristic point of inPath1 and path inPath2. The distance between a point and a path is computed as follows, depending on the value of inPathDistanceMode:

  • The distance to nearest characteristic point of inPath2, if inPathDistanceMode is set to PointToPoint.
  • The minimal distance to inPath2 segments adjacent to the nearest characteristic point of inPath2 (which is much more precise), if inPathDistanceMode is set to PointToSegment.

The operation computes the outDistance distance and, additionally, the outConnectingSegment line segment corresponding to the result.


The PathToPathDistance run on the sample paths produces outDistance = 9.509.

The resulting outConnectingSegment drawn onto the input paths.
