   vdcanvas.GetUserLine(_onActionGetDistanceStateChanged);
}

function _onActionGetDistanceStateChanged(action, status) {
    var vdcanvas = action.vdrawOwner();

    if (status == 'start') {
        vdcanvas.Prompt('pick first point');
    } else if (status == 'count') {
        vdcanvas.Prompt('pick second point');
    } else if (status == 'end') {
        vdcanvas.Prompt(':');
        if (!action.IsCanceled()) {
           var distance = vdgeo.Distance2D(action.ResValue[0], action.ResValue[1]);
           vdcanvas.Prompt('Distance = ' + distance.toString());
       }
