CAD blocks are named groups of objects that act as a single 2D or 3D object. They are used to create repeated content, such as drawing symbols or standard components. Blocks help you to save time, maintain consistency and reduce file size by re-using and sharing content rather than re-drawing it every time you need it.
With AutoCAD and AutoCAD LT software, you can create your own CAD blocks or choose from a large library of pre-made blocks, including:
Doors and windows
You can add attributes or dynamic properties to CAD blocks so they can accommodate different text strings, shapes or sizes. All CAD blocks can use the following properties:
A dynamic block has flexibility and intelligence. You can easily change a dynamic block reference in a drawing while you work, manipulating the geometry through custom grips or custom properties. Dynamic blocks let you adjust the block reference in place as needed, rather than search for another block to insert or redefine the existing one.
