Hi! I am learning how to create reducer family and I created one by using "blend", the 3d geometry works fine but when I try to draw a single line between the connecter centers to show in coarse level, I find I am not able to lock the endpoints of the line to the centers of the blend. Every time when the parameters change, the line will not change as expected. The reason I guess is for reducer family, there is offset for height and width, so the line actually is not in the same plane for the 2 main ref planes we see in the plan view. Is there anyone can tell me how to solve this problem? Any answer will be appreciated. (please see the image, the line is highlighted, and I attach my family too)
