Grouping Objects Together
Creating Blocks
A block is a group of objects that you can define as one object, or
block definition. For example, you could use individual objects such
as lines and curves to draw a symbol, and then you can define those
objects as a block that you can reuse from drawing to drawing. If at
some point you must edit the individual objects within the block,
then you can explode the block.
Key Concepts
■
Use the BLOCK command to define blocks to exist in the current
drawing only. Use the WBLOCK command to define blocks as .dwg
files that are independent of the current drawing.
■
You can create a library of blocks, each a frequently used
combination of objects.
■
You can create custom blocks and save them as external files to use
as symbols.
■
If you change the original block definition, then all references to
the block definition are updated automatically. However, if you
import a block definition from another file and that file is not
attached as an xref, any changes you make to the block definition
are not updated in the current file.
■
After you insert a block, you can scale, rotate, or explode it.
Exploding a block breaks it down into its component objects. You
can then modify the objects or redefine the block.
You can use AutoCAD block creation and definition tools as shown in
the following tasks.
