附加信息
The polyline.intersect returns no point intersection with the xFactor=1000 however cShape.intersect(gShape, 2) returns a line of length 0.0269786.
Intersection dimensions are mutually exclusive, since the geometries intersect as a line (1dim) the intersection they do not also intersect as a point (0dim).
User will need to run intersect twice to get both point and and line intersection, then to deal with each as desired.
How these geometries which are identical except for scale return different results will be due to the dataset's resolution and tolerance which affects how the geometries are stored and processes. With xFactor=1000 the 2 lines collapse and run coincidentally for a portion of their length causing a 2 dimention intersection.
Also best practice says geometric operations should not be done with unknown coordinate system.
