    Hi


    If I use from command line UCS "_ob" and select an object it moves and
    rotates my UCS tangent to this object. Thats OK.

    But when I made instruction in lisp (vl-cmdf "_ucs" "_ob" (list #ob pkt)) it
    moves and rotates my UCS to the end of object (if it's a polyline in the
    end of n-th element) even PKT is not a vertex.

    I tried to draw a tangent line to arc or spline from lisp.

    What am I doing wrong with (vl-cmdf "_ucs" "_ob" (list #ob pkt)) ??
    All OSNAPS are disabled.

    I don't want to use vlax-curve-getfirstderiv because it doesn't work it
    autocad lt.

    Any help will be greatfull
