Importing raster images into AutoCAD allows you to bring real-world images, such as aerial photographs, scanned drawings, or maps, directly into your drawing environment. This can be useful for tracing, overlaying information, or providing context for your design.
Steps to Import a Raster Image
Based on common AutoCAD workflows, here is a standard method to import a raster image:
The process often involves using the File menu options to attach or link an image file.
-
Access the Import/Link Option:
- Click the File menu.
- Select Import/Link.
- Choose Image from the options.
This step is directly supported by the provided reference: "Click File menu Import/Link Image."
-
Select Your Image:
- In the Open dialog box that appears, browse to the location of the raster image file you want to import.
- Select the desired image file.
- Click Open or OK.
This step is directly supported by the provided reference: "In the Open dialog box, select the image that you want to import."
-
Specify Insertion Options:
After selecting the image, AutoCAD typically presents a dialog box (like the "Attach Image" or "Image" dialog) where you can specify:- Insertion Point: Where the lower-left corner (or other base point) of the image will be placed in your drawing (you can specify coordinates or pick a point on screen).
- Scale: The size of the image in drawing units.
- Rotation: The angle at which the image will be inserted.
- You might also see options for path type (full path, relative path, no path) for the linked image.
-
Place the Image:
Once you confirm the options in the dialog box, the image will be inserted into your drawing at the specified location, scale, and rotation.
Common Raster Image Formats
AutoCAD supports several common raster image file formats for import, including:
- JPEG (.jpg, .jpeg)
- PNG (.png)
- TIFF (.tif, .tiff)
- BMP (.bmp)
The ability to import various formats makes it versatile for different sources like digital cameras, scanners, and online maps.
Why Import Raster Images?
Raster images serve numerous purposes in CAD drawings:
- Underlays: Placing a scanned drawing or map beneath your design to trace or reference.
- Context: Adding site photos or aerial imagery to provide visual context.
- Digitizing: Converting information from paper maps or images into digital CAD data.
Using the "Import/Link Image" method through the File menu is a straightforward way to bring these visual elements into your AutoCAD project, linking them to your drawing rather than embedding them directly, which helps keep drawing file sizes manageable.
