Understanding Raster Images in AutoCAD
Raster images, commonly used in design and drafting, can occupy unnecessary space in your AutoCAD drawings if not managed correctly. This guide provides a comprehensive step-by-step process for deleting raster images in AutoCAD, specifically tailored for AutoCAD 2025.
Step 1: Identify the Raster Image
Before proceeding to delete a raster image, ensure that you can clearly identify the raster object you wish to remove. This could include images embedded in your drawing or linked from external files.
Step 2: Open the External References Palette
- Navigate to the View tab on the ribbon at the top of the AutoCAD workspace.
- Find and click on the External References button. This will open the External References palette, displaying a list of all linked images and files within your current drawing.
Step 3: Locate the Target Image
In the External References palette, sift through the list to find the image you want to delete. This can be done by scrolling through the entries or using the search function within the palette if available.
Step 4: Detach the Image
- Once you’ve located the desired image in the External References palette, right-click on the image name.
- Select Detach from the context menu. This action unlinks the image from your drawing file and concurrently removes all instances of that image from your workspace.
Step 5: Verify Deletion
After detaching the image, verify that it has been removed:
- Click on different areas of your drawing where the image previously existed.
- Ensure that no remnants are visually present in your workspace.
Deleting Raster Objects from the Drawing
For raster images defined as objects such as REM regions or bitonal regions, follow these steps:
Step 6: Select the Raster Object
- Click on the raster object you want to delete. If the raster image is not immediately selectable, ensure that you are in the correct layer or use the Layer Properties Manager to make it active.
- If necessary, zoom in to ensure accurate selection, or utilize the Select command for precision.
Step 7: Use the ERASE Command
- With the raster object selected, type ERASE in the command line.
- Press Enter to execute the command. The selected raster object will now be removed from your drawing.
