### Remarks

Both points must be finite and further apart than [\_minEdgeLength](/engine/6000.7/script-reference/unity/u2d/physics/physicsworld/minedgelength.md). See [\_areEdgesValid](/engine/6000.7/script-reference/unity/u2d/physics/segmentgeometry/areedgesvalid.md) for the point separation on its own.
