Does AutoCAD Have Built in Blocks?

AutoCAD is a powerful software used by architects, engineers, and designers for creating detailed and accurate 2D and 3D drawings. One of the key features of AutoCAD is its ability to work with blocks.

But what exactly are blocks in AutoCAD, and does AutoCAD have built-in blocks? Let’s dive into the world of AutoCAD blocks and find out.

Understanding Blocks in AutoCAD

Blocks in AutoCAD are pre-defined collections of objects that can be reused throughout a drawing or even across multiple drawings. They are like reusable templates that can save time and effort when creating complex drawings. Blocks can be simple objects or more intricate designs, such as furniture, doors, windows, or entire building plans.

When you create a block in AutoCAD, you define its geometry and attributes. Once defined, you can insert the block into your drawing multiple times at different locations or scales without having to recreate it from scratch each time.

Creating Custom Blocks

To create custom blocks in AutoCAD, you can either draw the objects directly within the Block Editor or convert existing objects into a block. The Block Editor provides a dedicated environment where you can modify and fine-tune your block’s geometry, attributes, and behavior.

To access the Block Editor in AutoCAD, simply type “BEDIT” on the command line or right-click on an existing block and select “Edit Block.” In this editor, you have all the familiar drawing tools at your disposal to create or modify your block’s components.

AutoCAD’s Built-in Blocks Library

Yes, AutoCAD does come with a library of built-in blocks that cover various commonly used objects. These blocks are available as part of the standard installation and can be easily accessed through the Design Center.

The Design Center is a powerful tool in AutoCAD that allows you to browse and insert content from various sources, including the built-in blocks library. To open the Design Center, simply type “ADCENTER” on the command line or use the shortcut “Ctrl+2.”

Once opened, navigate to the Blocks section within the Design Center window. Here, you’ll find a wide range of pre-defined blocks organized into categories such as architectural, electrical, mechanical, and more. You can preview each block before inserting it into your drawing.

Inserting Blocks from the Library

To insert a block from AutoCAD’s built-in library, follow these steps:

  • Open the Design Center by typing “ADCENTER” on the command line or using the shortcut “Ctrl+2.”
  • Navigate to the Blocks section within the Design Center window.
  • Select the desired block category.
  • Browse through the available blocks and click on one to preview it.
  • Click on the “Insert” button to place the block in your drawing.

Customizing Built-in Blocks

The great thing about AutoCAD’s built-in blocks is that they are highly customizable. Once inserted into your drawing, you can modify their geometry, attributes, and properties to suit your specific needs.

To modify a built-in block in AutoCAD:

  1. Select the block you want to modify.
  2. Type “REFEDIT” on the command line or right-click and select “Edit Reference.”
  3. In the Reference Edit dialog box, you can make changes to individual objects within the block definition.
  4. Once you’ve made the desired modifications, save and exit the Reference Edit dialog.


AutoCAD does indeed have a built-in library of blocks that can be easily accessed through the Design Center. These pre-defined blocks cover a wide range of objects commonly used in architectural, electrical, and mechanical drawings.

However, it’s important to note that you can also create your own custom blocks using AutoCAD’s Block Editor. This flexibility allows you to streamline your workflow and enhance your productivity when working with AutoCAD.

So whether you choose to use the built-in blocks or create your own, incorporating blocks into your AutoCAD drawings can save you valuable time and effort while ensuring consistency and accuracy across your designs.
