A method and system are described for generating railing objects that model railing structures, such as fences. According to the method, a railing object is generated along a path within a design layout. As rendered, the railing object includes posts and railings, with the option of using filling material between the posts. According to one variation, the railing object substantially follows an existing path. The railing object may comprise an increasing number of segments to better follow the curvature of the path. Any modification applied to the path is automatically applied to the railing object after the railing object is applied to the path. That is, every railing object component (e.g. post, railing, fencing) will be repositioned along the new position of the path. A mechanism is provided for automatically applying the modifications to the geometric dimensions of a single component instance of a railing object to every instance of that component on the railing object. A mechanism is also provided for positioning corners in the railing object to match corners on the path. |
