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.
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.
You can draw something once and use it many times as a block insert to avoid extra work and save time.
All insertions of a block are automatically updated when you modify a block definition.
It is easy to standardize drawings and have a consistent approach when everyone in an office uses the same symbol library for blocks.
