I need to create a polyLine that goes through 100 points. Is there any way that I can write the python code which uses the array of points to generate the polyLine?
yes you can.
Use the function CreatePolyLine from the module XCoreModeling
This function takes a list of points as input. Points need to be Vec3 objects
from s4l_v1.model import Vec3
#points is your array of 100 points with spatial coordinates
points = [Vec3(p) for p in points]
