Table Of Contents
landing gap An optional space between a leader tail and the leader content.
layer A logical grouping of data that are like transparent acetate overlays on
a drawing. You can view layers individually or in combination. (LAYER)
layer index A list showing the objects on each layer. A layer index is used to
locate what portion of the drawing is read when you partially open a drawing.
Saving a layer index with a drawing also enhances performance when you
work with external references. The INDEXCTL system variable controls whether
layer and spatial indexes are saved with a drawing.
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.
