layer translation mappings Assignments of a set of layers to another set of layers that
defines standards. These standards include layer names and layer properties. Also called
layer mappings.
layout The environment in which you create and design paper space layout viewports to
be plotted. Multiple layouts can be created for each drawing.
layout viewports Objects that are created in paper space that display views. See also paper
space. (VPORTS)
leader tail The portion of a leader line that is connected to the annotation.
lens length Defines the magnification properties of a camera's lens. The greater the lens
length, the narrower the field of view.
level of smoothness The property assigned to a mesh object to control how much the edges
of the object are smoothed. Level 0 (zero) represents the least rounded shape for a specified
mesh object. Higher levels result in increased smoothness.
light glyph The graphic representation of a point light or a spotlight.
limits See drawing limits.
line font See linetype.
linetype How a line or type of curve is displayed. For example, a continuous line has a
different linetype than a dashed line. Also called line font. (LINETYPE)
lineweight A width value that can be assigned to all graphical objects except TrueType

fonts and raster images.
link To use object linking and embedding (OLE) to reference data in another file. When
data is linked, any changes to it in the source document are automatically updated in any
destination document. See also embed.
LL84 coordinate system Common latitude longitudinal-based coordinate system where
latitude and longitude are both measured from -90 to 90 degrees.
Longitude begins at 0 degrees at the Prime Meridian in Greenwich, England and is measured
from -180 to 180.
Latitude is 0 degrees at the equator and is measured from -90 to 90.
lofted solid/surface A solid or surface that is drawn through a set of two or more
cross-section curves. The cross sections define the profile (shape) of the resulting solid or
surface. Cross sections (generally, curves or lines) can be open or closed. (LOFT)
lookup property In a dynamic block definition, a lookup parameter that you add to a
lookup table. The lookup parameter label is used as the property name. When the parameter
