BLOCK
Create Block Libraries
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 draw-
ing that you are working on. Block library drawings are not different from
other AutoCAD 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 that can be viewed
in DesignCenter.
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.
