                var dimstyle = new vddimmanager(); //create the object
                dimstyle.BLK = 'dimblck1';
                //create a dimension using the above dimension manager properties
                var dim = dimstyle.Create(vdcanvas, [-3, -2, 0], [3, -2, 0], [0, 0, 0]); //the dimension will be added in the entities of the layout
                vdcanvas.DrawEntity(dim); //draw the new object on the canvas
