Table Of Contents
label block
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.
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.
