How to Select Similar Objects in AutoCAD?

Understanding Object Selection in AutoCAD

Selecting similar objects in AutoCAD can significantly improve your workflow, especially in larger projects. Using the appropriate command allows you to quickly highlight all objects of a specific type, thus saving time and effort. Here’s a detailed guide on how to accomplish this effectively in AutoCAD 2025.

Using the SELECTSIMILAR Command

One of the simplest methods to select similar objects is through the SELECTSIMILAR command. Follow these steps:

1. Type SELECTSIMILAR in the command line and press Enter.
2. Select any object from the drawing that represents the category you wish to highlight. For instance, if you want to select all lines, just click on one line.
3. AutoCAD will automatically highlight all similar objects in the drawing, based on the type of object you selected.

Selecting By Right-Clicking

An alternative approach is to use the right-click function for a context menu option:

1. Click on an object that you want to use as a reference for your selection.
2. Right-click on the selected object.
3. Select Select Similar from the context menu that appears. All objects similar to the one you selected will then be highlighted.

Filtering Objects with Quick Select

If you need to filter objects based on specific attributes or properties, you can use the Quick Select feature:

1. Open the Properties palette from the menu.
2. Click on the Quick Select button to open the Quick Select dialog window.
3. In the dialog, set the Object Type to the desired category, such as Block Reference.
4. Under Property, choose the specific property you want to filter by, like Name.
5. For Operator, typically leave it as = Equals.
6. In the Value section, select the name of the block or object you wish to target from the dropdown list.
7. Click OK to execute the selection. All matching objects will be selected.

Utilizing Layer Selections

To efficiently select all objects on a particular layer, follow these steps:

1. Access the Layers panel within the software.
2. Hold the Control key (or Command key for Mac users) and click on the name of the layer that contains the objects you want to select.
3. This will create a selection encompassing every object present on that layer.

Using Multiple Selection Methods

For selections that require more complexity, consider combining various methods:

1. Utilize the crossing or window selection. Click once to start your selection box, drag the cursor to encompass your desired items, and click again to finalize.
2. Alternatively, for manual selections, hold down the Shift key while clicking on objects to add them to your current selection.

Displaying All Objects in AutoCAD

If you wish to view all objects within your drawing, ensuring no elements are hidden, follow these steps:

1. Type OPTIONS in the command line to access the Options window.
2. Navigate to the Display tab.
3. Locate the Layout elements section and check the box next to Display Layout and Model tabs.
4. Click OK to apply the changes and close the window.
