Sweep Patches
Generic swept surfaces consist of 2 or more curves joined end-to-end
In NURBS modelling they are called U,V pairs
Surface created by uniformly deform one curve to another
The quality of surface is determined by bounding lines

Crease Lines
Differentiate sweep forms from blobs
Created by the meeting of two different planes or surfaces
May be positive or negative, but has more inherent 'integrity' than a feature line
Persistent elements, dominate the form even after filleting
Effective carrier of meaning and emotion
The edges where sweep patches meet in CAD
Voluminous Form
Compare the forms in terms of Useable volume: Most of the internal space can be used to house
mechanisms Stance: Viewers look from the ‘best-looking' side
Virtual Edges
Family of curves add dynamism to forms There are times when it is not possible to place curves on a product form Curves can be ‘drawn’ on near flat surface as high-lights by bending the
surface

Highlights
Highlights are areas of a surface that reflect major light source to the viewer
Compare with planar, cylindrical or ruled surfaces, glossy sweep surfaces produce smaller and more dynamic, flowing highlights
The more pronounce a sweep surface is, the more complicate the highlights will be
The background reflection is intensified by double curvature of sweep surface
Edge enhancement
Face-breaking
Relax surface

Voluminous Form
Transfer the curve family to a 150X150X150 foam cube The new form should be able to house a cube 100X100X100 big Make good use of the 25 thick zone
