Hi, not sure to understand, but you can get the points with GetPointAtParameter method of any curve derived object, so, you can get the parameters with the StartPoint and EndPoint properties of any curve derived object, the middle point can be obtained with the distance, get the total length substracting the distance at StartParameter from the distance at  EndParameter divide by 2 and then get the point at that distance with GetPointAtDistance.
