2.4.1 - Object Properties

Every AutoCAD object, such as a line or a circle, has properties.
Object properties control the appearance and behavior of objects and are used to organize a drawing.
Some properties such as Color, Linetype, and Layer are common to all objects.
Every object has general properties, including its layer, color, linetype, linetype scale, lineweight, transparency, and plot style.
In addition, some objects have properties that are specific to their type.
For example, the unique properties of a circle include its radius and area.
When you select an object, its properties or quick properties palette is displayed and lists the selected object's properties.  When more than one object is selected, only those properties common to all selected objects are displayed.
When you specify the current properties in a drawing, all newly created objects use those settings automatically. For example, if you set the current layer to Walls, the objects you make will be on the Walls layer.

Use the Properties Palette

The Properties palette (Fig. provides a complete list of all property settings.
• If a single object is selected, you can view and change the properties for that object.
• If several objects are selected, you can view and change their common properties.

Quick Properties palette

  • On the “Drawing Status Bar” (Fig., turn on the icon Quick Properties .
    After this, when you click an object, the Quick Properties palette opens, and you can make changes to its properties (Fig.
