 var box = vdcanvas.GetEntityBBox(ents);//the bounding box of all entities
if (box) {//if the entity exist
    var pt1 = vdgeo.newpoint(box[0], box[1], box[2]); // The lower left point of the bounding box 
    var pt2 = vdgeo.newpoint(box[3], box[4], box[5]); // The upper right point of the bounding box 
    var center = vdgeo.MidPoint(pt1, pt2); // The middle point between lower left and upper right point of the bounding box 
}
vdcanvas.CmdScale(ents, center,[-1.0,1.0,1.0,0])//through CmdScale command
