Hej
I am trying to contrain an spline to those references lines to build an insulation detail family paramtric. All the references families flex appropiately, but my problem is that I cant constrain the spline to those vertex (blue circles) When I am trying to do it then the spline aligned to the red circle, (same vertical). Why is this happening? Why always end and start of an spline be in the same line (either vertical or horizontal).
