CAD blocks

What are CAD blocks?

CAD blocks are named groups of objects that act as a single 2D or 3D object. You can use them to create repeated content, such as drawing symbols, common components, and standard details. Blocks help you save time, maintain consistency, and reduce file size, since you can reuse and share content.

How do I use CAD blocks?

You can create your own CAD blocks or choose them pre-made in both AutoCAD and AutoCAD LT software. Insert a block into a CAD drawing either by specifying a drawing file or block definition within a drawing file. Then, you can easily move, copy, rotate, or scale it.

What are dynamic blocks?

Dynamic blocks can save you time and decrease file size. Create one block that can change shape, size, or configuration depending on usage instead of inserting multiple static blocks. Add attributes or dynamic properties to CAD blocks, so they can accommodate different text strings, shapes, or sizes.

Why should I use dynamic blocks?

Dynamic blocks have flexibility and intelligence. You can easily change a dynamic block reference in a drawing while you work, manipulating the geometry through custom grips or properties. You can adjust the block reference in place. For example, instead of creating multiple blocks for different table types and chair settings, you can create one table block.
