What Are Blocks?

A block definition is a named imprint for a selection set of objects.

when this imprint is stored in the current drawing it can be easily  inserted any number of times at various scales and orientations.
an inserted block is one object that can be selected by selecting any part of the inserted block.
 The most common use of blocks is for drawing symbols.
you can create your own symbol library or purchase libraries of  standard drafting & design symbols.
typical symbols from various industries are shown below.

Faster Drawings

Use blocks for drawing symbols to minimize disk space and maximize AutoCAD performance.

each additional block insert requires only a small amount of additional storage space compared to multiple copies of objects.

Less Work

You can draw something once and use it many times as a block insert to avoid extra work and save time.

Automatic Update

All insertions of a block are automatically updated when you modify a block definition.

Standard Dwgs

It is easy to standardize drawings and have a consistent approach when everyone in an office uses the same symbol library for blocks.
