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.

  • Why is this option not available in a 2D model?

    It seems like a very basic set of constraints and should be equally applicable to both 2D and 3D models.
