The Mechanical Forms
Cubes, cylinders and their Boolean results are easy to machine
Mechanical forms lack the subtle, interesting changes in silhouette and high-lights which free-forms possess
To make geometrical forms interesting, designers focus on dramatic overall compositions or play around with graphical tricks such as asymmetry, contrast, repetition, etc.
Discussion
Internal edges aligned to one or two directions. Everything snap to an invisible ‘grid’. The overall result is a sense of order emerge from microscopic chaos

The Aesthetic Judgement for Geometrical Form Design
Good product forms are those which produce interesting 2D image at all viewing angles
Interesting 2D images are the result of variation and contrastVolumetric proportionSilhouette contoursGraphical elements on surfaces
The Developable Forms
Ruled Surfaces
Ruled surfaces are transitional surfacesbetween two open or closed profilesBetween one open or closed profile and a point
There must be at least one straight line that connect any point on the one profile to the other profile or point
Planes and Cylindrical surfaces are a sub-set of ruled surfaces
Developable Surface
In mathematics, a developable surface is a surface that can be flattened onto a plane without distortion
Many developable surfaces can be visualised as the surface formed by moving a straight line in space
Developable surfaces that can be realized in 3D space are cylinders, cones, planes
Spheres are not developable as they cannot be unrolled into a plane
All developable surfaces are ruled surfacesNot all ruled surfaces are developable surface,
hyperboloids are examples of ruled surfaces that are not developable
Developable Product Forms
Straight ruled surfaces appears on many products formed by folding and bending sheet materials
Skilful combination of ruled surfaces can make a mathematically simple developable surface looks as dynamic as very complex surface
By introducing free-form curves and varying the matching endpoints, designers can introduce dynamism to the product form

Sweep Patches
Sweep Surfaces
Sweep surfaces are transitional surfacesBetween 2 profiles connected at a common
end pointBetween 3 profiles connected at 2 or 3 common
end pointsBetween 4 profiles connected at 4 common end
points
Planes, Cylindrical, and Ruled surfaces are a sub-set of sweep surfaces
Generic swept surfaces consist of 2 or more curves joined end-to-end
In NURBS modelling they are called U,V pairs
From any point on one profile
At least 1 straight line to other profile
Single curvature
Not single curvature
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
