How to move one bspline so is tangent to other two

I have 3 splines, and I want to move one of them so is tangent to the other two, is that possible?

I want to move the selected spline to a position where it is perfectly tangent to the two below (which can't be moved).

This was done "by hand":

However, if you zoom in, they are not tangent (to any zoom in):

  • Please advise on version being used.

    If using MicroStation CONNECT Edition one option is to use 3D Constraints.

    First you will need to 'Fix' the curves not to be moved, then Constrain the remaining curve to them.

    If when your  finished and  you  use the remove constraints option from the contraints  tool , does  it leaves the  lines where you left them  tangential but  not  constrained as we may want to modify the lines at a later time.. and  it makes it hard  on next user  to figure out its constrained as we turn off the markers ie no hints left... haha...

  • If you remove constraints from the object, although keeps its position, it's no longer linked anymore, so there's no point in saying that the next user won't figure out that is constrained because it's not, it's like if you neved constrained it but it's in a different position.
