170 | Chapter 14 Control the Properties of Objects
Overview of Object Properties
Every object you draw has properties. Some properties are general and apply
to most objects; for example, layer, color, linetype, and plot style. Other
properties are object-specific; for example, the properties of a circle include
radius and area, and the properties of a line include length and angle.
Most general properties can be assigned to an object by layer or can be
assigned to an object directly.
■ When a property is set to the value BYLAYER, the object is assigned the
same value as the layer on which it is drawn.
For example, if a line drawn on Layer0 is assigned the color
BYLAYER, and
Layer0 is assigned the color Red, the line is red.
■ When a property is set to a specific value, that value overrides the value
set for the layer.
For example, if a line drawn on Layer0 is assigned the color Blue, and
Layer0 is assigned the color Red, the line is blue.

Display and Change the Properties of Objects
You can display and change the current properties for any object in your
drawing in the following ways:
■ Open the Properties palette and view and change the settings for all prop-
erties of the object.
■ View and change the settings in the Layer control on the Layers toolbar
and the Color, Linetype, Lineweight, and Plot Style controls on the Prop-
erties toolbar.
■ Use LIST to view information in the text window.
■ Use the ID command to display a coordinate location.
Note For all methods except the ID command, the PICKFIRST system variable
must be on (set to 1, the default).
