Improving the upper surface<br />

SHOE DESIGN AND VISUALIZATION WITH RHINOCEROS<br />

The upper <strong>and</strong> sole surfaces are not as smooth <strong>and</strong> well defined as we would like them to<br />

be. Improving the surfaces requires additional cross-section curves to better control the<br />

surface creation.<br />

To create additional input curves for the upper<br />

1 In the Right viewport, on the construction<br />

plane, create two curves as shown. (Curve<br />

menu: Free-Form > Control Points)<br />

2 Use the Project comm<strong>and</strong> to project these<br />

two curves onto the upper surface. (Curve<br />

menu: Curve From Objects > Project)<br />

3 In the Top viewport, use the Hide comm<strong>and</strong> to remove the last surface from the<br />

view. (Edit menu: Visibility > Hide)<br />

We will now be able to see imperfections in the section curves.<br />

To improve the quality of the cross-section curves<br />

1 Rebuild the curves with 30 control points <strong>and</strong> degree 3. (Edit menu: Rebuild)<br />

Once the curve has been rebuilt, there still may be imperfections that we cannot<br />

see clearly.<br />
