Create Block Libraries
A block library is a collection of block definitions stored in a single drawing
file. You can use block libraries supplied by Autodesk or other vendors or
create your own.
You can organize a set of related block definitions by creating the blocks in
the same drawing file. Drawing files used this way are called block, or symbol,
libraries. These block definitions can be inserted individually into any drawing
that you are working on. Block library drawings are not different from other
drawing files except in how they are used.
When you use BLOCK to define each block definition in the block library
drawing, you can include a short description of the block.
Optionally, you can also document each block definition by inserting it in
the drawing area of the library drawing. In addition to the block geometry,
you can include text that provides the block name, the date of creation, the
date of the last modification, and any special instructions or conventions.
This creates a visual index of the blocks in the block library drawing.
Use the Content palette to view and insert block definitions from the current
or an existing drawing. Insert a block from the Content palette does not
overwrite an existing block definition in a drawing with one that comes from
another drawing.
Attach Data to Blocks (Block Attributes)
You can attach information to blocks and later extract the information to
create a bill of materials or other report.
