    1.-Draw a B-Spline curve using B-Spline by reference point;

    2.-Do the last 2 points near applying dimension;

    3.-Draw a reference line between both points ;

    4.- Now, draw a line witch start from the last B-Spline Point and apply co-linear constrain between this line and the reference line;

    5.- Edit the dimension to the minimal feasible (mathematical Limit concept);

    6.-Now click "select" and move the line to make sure that still is tangent to the B-Spline.
    (some point may needs coincident constraint).

    I hope this help.

    This method has better behavior in ADV11.2 than the last one in my other laptop.
