How Do I Create a 2D Block in AutoCAD?

Creating a 2D block in AutoCAD is a fundamental skill that every CAD designer should master. Blocks are reusable objects that can save you time and effort by allowing you to insert them multiple times in your drawings. In this tutorial, we will walk you through the step-by-step process of creating a 2D block in AutoCAD.

Step 1: Drawing the Block

To create a 2D block, you first need to draw the object or geometry that you want to turn into a block. This could be anything from a simple shape like a rectangle or circle to more complex objects like furniture or architectural elements.


If your block consists of multiple entities, it’s a good idea to group them together using the Group command (CMD+G). This will make it easier to select and modify the entire block as one unit later on.

Step 2: Defining the Block

Once you have drawn your object, it’s time to define it as a block. To do this, follow these steps:

  • Select all the entities that make up your block by either clicking and dragging over them or using a selection window.
  • Type BLOCK in the command line and press Enter.
  • In the Block Definition dialog box, enter a name for your block. Choose something descriptive so that it’s easy to identify later on.
  • Select the desired insertion point for your block. This is where AutoCAD will place the base point of your block when you insert it into other drawings.
  • Note: You can also specify other properties such as scale, rotation, and alignment in the Block Definition dialog box if needed.
  • Click OK to create the block.

Step 3: Saving the Block

Now that you have defined your block, it’s time to save it so that you can use it in other drawings. To save your block, follow these steps:

  • Type SAVE in the command line and press Enter.
  • In the Save Block dialog box, choose a location to save your block file. It’s a good practice to keep all your blocks in a separate folder for easy access.
  • Type a name for your block file and click Save.

Step 4: Inserting the Block

To insert your newly created block into another drawing, follow these steps:

  • Type INSERT in the command line and press Enter.
  • In the Insert dialog box, navigate to the location where you saved your block file.
  • Select the desired block from the list of available blocks.
  • Select the insertion point for your block in the drawing area. You can use object snaps (F3) or specify exact coordinates if needed.
  • Note: You can also modify other insertion options such as scale and rotation angle in the Insert dialog box if required.
  • Click OK to insert the block into your drawing.

Congratulations! You have successfully created and inserted a 2D block in AutoCAD.

Blocks are a powerful feature that can significantly enhance your productivity when working on CAD drawings. By creating reusable blocks, you can save time and maintain consistency throughout your designs.

Remember to practice creating and using blocks regularly to become proficient in this essential AutoCAD skill.
