How Many Types of Blocks Are There in AutoCAD?

AutoCAD is a powerful software used by architects, engineers, and designers to create precise and detailed drawings. One of the key features of AutoCAD is its ability to work with various types of blocks. In this article, we will explore the different types of blocks in AutoCAD and how they can be used.

1. Insertion Blocks:
Insertion blocks are the most common type of block in AutoCAD.

They are created by drawing a set of objects and then saving them as a block. Insertion blocks can be inserted into your drawing multiple times, allowing you to reuse common elements such as furniture, symbols, or annotations.

Let’s say you are creating a floor plan for a building. Instead of redrawing doors and windows every time, you can create insertion blocks for them and insert them whenever needed. This saves time and ensures consistency throughout your drawing.

2. Dynamic Blocks:
Dynamic blocks take insertion blocks to the next level by adding flexibility and interactivity. With dynamic blocks, you can create parameters and actions that modify the appearance or behavior of the block when it is inserted.

Imagine you have created a dynamic block for a door. You can add parameters such as width and height, which can be adjusted after insertion using grips or properties palette. This allows you to easily customize the door size without redrawing it.

3. Attribute Blocks:
Attribute blocks are similar to insertion blocks but have additional properties called attributes. Attributes are text fields that can contain information such as part numbers, names, or descriptions.

If you are creating a drawing for a product catalog, you can use attribute blocks to add attributes like part numbers or prices to your products. These attributes can be easily edited after insertion, making it convenient for updating information.

4. Xrefs (External References):
Xrefs are blocks that are referenced from external files.

This allows you to collaborate with others by linking their drawings into your own. Any changes made to the referenced file will automatically update in your drawing.

Suppose you are working on a project with multiple disciplines, such as architecture, structure, and MEP (Mechanical, Electrical, Plumbing). Each discipline can work on their own drawings and reference them into a master drawing to ensure coordination and avoid duplication of effort.


AutoCAD offers various types of blocks that enhance productivity and efficiency in your drawing workflow. Whether you need to reuse common elements, create flexible designs, add attributes, or collaborate with others, blocks provide a versatile solution. By mastering the different types of blocks in AutoCAD, you can optimize your design process and create accurate and professional drawings.
