# Form in 3D

Using the definitions of Linear Form, Planar Form, and Solid Form as a guide, we will start to create geometric shapes in class.  You will need one shape for each definition.  The objects can be anything but should fit the definitions.

A general definition of Form:  Form refers to the visual and physical structure of an object.  It is three-dimensional.  Form cannot exist without space, and space is an aid to the perception and appreciation of form.

Linear Form–  It has been stated that a one-dimensional object is nonexistent in the environment.  However true or false this statement may be, let us assume that a linear form is one which possesses an exaggerated dimension, that of length; it is considerably longer that it is high or wide.  In linear form, space is articulated with a minimum of mass, by a long thin element.

Planar Form– When width is added to length, and thickness or height is still a minor aspect, planar form results.  The planar form is composed of long, wide, and thin shapes that articulate the space.  For our purposes, we will not adhere to a mathematical perspective that defines the planar form as a flat surface.  Any curved or otherwise irregular surface that has two exaggerated dimensions may be classified as a planar form.

Solid Form–  When space appears to be excluded from the form– when length, width, and thickness or height are near equilibrium– a solid form exists.  A solid form is completely surrounded by space; that is, it is defined by the space.  It may exist as a monolithic form, a uniform mass not penetrated by space.  In addition to the pure monolith, forms that contain concave and convex and negative areas may be categorized as solid forms as long as the proportion of mass is greater than the space penetrating the form.
