landing

The portion of a leader object that acts as a pointer to the object being called
out. A landing can either be a straight line or a spline curve.

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.

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.

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)
