Objects creation and modification	Creating and using blocks
Introduction to blocks
Overview     Operations     Commands

Blocks can be created and used in several ways:

• combining objects to create a block definition in the current drawing;
• Using the Blocks Manager  to manage the blocks already inserted in the current drawing;
• you can create a drawing file and later insert it as a block in other drawings;
• you can create a drawing file with several block definitions to serve as a block-part library.

A block can be composed of objects drawn on several layers with various colors, linetypes and lineweight properties. Although a block is always inserted on the current layer, the block reference preserves information about the original layer, color and linetype properties of the objects that are contained in the block. It is possible to control whether the objects in a block retain their original properties or inherit their properties from the current layer, color, linetype or lineweight settings.

You can use Remove selected block to remove unused block definitions from a drawing.
