Table Of Contents
When you insert a block you are inserting a block reference. The information
is not copied from the block definition to the drawing area. Instead, a link is
established between the block reference and the block definition. Therefore,
if the block definition is changed, all references are updated automatically.
Use PURGE to remove unused block definitions from a drawing.
Blocks and Layers
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. You can control whether objects in a block retain their original
properties or inherit their properties from the current layer, color, linetype,
or lineweight settings.
Annotative Blocks
You can also create blocks. For more information about creating and working
with an annotative blocks, see
Create Annotative Blocks and Attributes on
page 667.
