solid history A property of a solid that allows you to see and modify the original forms of
the solid.
solid object An object that represents the entire volume of an object, for example a box.
solid primitive A basic solid form. Solid primitives include: box, wedge, cone, cylinder,
sphere, torus, and pyramid.
spatial index A list that organizes objects based on their location in space. A spatial index
is used to locate what portion of the drawing is read when you partially open a drawing.
Saving a spatial index with a drawing also enhances performance when working with external
references. The INDEXCTL on page 2365 system variable controls whether layer and spatial
indexes are saved with a drawing.
specular reflection The light in a narrow cone where the angle of the incoming beam equals
the angle of the reflected beam.

STB file For plot style table file. Contains plot styles and their characteristics.

action, determines how the objects within or crossed by the frame are edited in the block
reference.
sub-prompt A command prompt that instructs for a form of input to complete a command
or alter a property.
subdivision A division, or tessellation in a mesh object. As a mesh object is smoothed, the
number of subdivisions increases.
