To weight selected edges, hold down the period key (‘.’) and drag. To weight selected edges and all
points connected to them, hold down the period key and Shift-drag. To weight selected edges and
their shared points, hold down the period key and Ctrl-drag.
Polygon mode
Selected polygon. ‘.’ + drag. ‘.’ + Ctrl-drag.
To weight all points and edges of the selected polygons, hold down the period key (‘.’) and drag. To
weight only the edges of the selected polygons, hold down the period key and Ctrl-drag.
Manual weighting
Select the elements (i.e. points, edges or polygons) that you want to weight. Select the Live Selection
tool. You can now edit the HyperNURBS weighting parameters in the Attribute manager on the
HyperNURBS Weights tab.
Select the Live Selection tool and edit the weighting parameters in the Attribute manager.
To assign a specic weight to the selected elements such as 60%, set Mode to Set, set Strength to
the desired value and click the Set button. To add or subtract weight, set Mode to Add or Sub, set
Strength to the amount that you want to add or subtract and click Set.
Modeling with HyperNURBS
Keep the following in mind when modeling with HyperNURBS:
Use rectangles in preference to triangles — triangles tend to disrupt the smooth ow of the
HyperNURBS surface. However, don’t be afraid to use triangles if you must. Place the triangles in
areas where there are lots of points close together, to conne the distortion to a small area. You can
often avoid visible distortion by tucking the triangles away in the less critical areas.
