How Do I Match Block Properties in AutoCAD?

AutoCAD is a powerful software tool used by architects, engineers, and designers for creating and editing 2D and 3D designs. One of the key features of AutoCAD is the ability to work with blocks, which are pre-defined objects that can be reused throughout a drawing. In this tutorial, we will explore how to match block properties in AutoCAD.

Understanding Block Properties

Before we dive into matching block properties, let’s first understand what block properties are. Block properties are the characteristics or attributes assigned to a block. These can include things like color, layer, linetype, scale, rotation angle, and more.

When you insert a block into an AutoCAD drawing, it will inherit the properties of the original block definition. However, there may be cases where you want to change certain properties of a block instance without modifying the original definition. That’s where matching block properties comes in handy.

The ‘Match Properties’ Command

The ‘Match Properties’ command in AutoCAD allows you to copy the properties of one object and apply them to another object. This can be particularly useful when you want to match the properties of one block instance with another.

To use the ‘Match Properties’ command:

  • Select the object with the desired properties (the source).
  • Type MATCHPROP on the command line.
  • Select the objects that you want to apply the matched properties to (the Targets).
  • Press Enter or right-click to finish the command.

The selected objects will now have their properties updated to match those of the source object.

Matching Specific Block Properties

In some cases, you may not want to match all of the properties of a block instance. AutoCAD allows you to specify which properties you want to match using the ‘Match Properties’ command.

To match specific block properties:

  • Select the source object with the desired properties.
  • In the ‘Match Properties’ dialog box, select the properties you want to match. You can choose from options like color, layer, linetype, lineweight, and more.
  • Select the objects that you want to apply the matched properties to.

The selected objects will now have their specified properties updated to match those of the source object.

Matching Block Properties Across Drawings

AutoCAD also allows you to match block properties across different drawings. This can be useful when you have similar blocks in multiple drawings and want to ensure consistency in their properties.

To match block properties across drawings:

  • Open both the source drawing (with the desired block properties) and the Target drawing (where you want to apply those properties).
  • In the Target drawing, type XREF on the command line and press Enter.
  • In the ‘External Reference’ dialog box, click on ‘Attach DWG’ and select the source drawing file.
  • Select ‘Overlay’ as the attachment type and click ‘OK’.
  • Type MATCHPROP on the command line and follow similar steps as mentioned earlier to match block properties between drawings.

The blocks in your Target drawing will now have their properties updated based on those from the source drawing.


Matching block properties in AutoCAD is a powerful feature that allows you to quickly update the properties of block instances. Whether you want to match all properties or only specific ones, the ‘Match Properties’ command has got you covered. With the ability to match properties across drawings, you can ensure consistency and efficiency in your AutoCAD workflow.

So go ahead and give it a try! Experiment with matching different block properties and see how it can enhance your AutoCAD experience.
