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 DesignCenter to view and copy block definitions individually from block
library drawings (or from any existing drawing) to your current drawing.
DesignCenter does not overwrite an existing block definition in a drawing
with one that comes from another drawing.
To create a block library drawing
1 Begin a new drawing.
2 Define a block.
3 Repeat step 2 for as many related block definitions as you want to make.
4 Save the drawing using a name appropriate for a library drawing.
These blocks can be inserted into any drawing using DesignCenter
(ADCENTER).
