How to Export PNG in AutoCAD?

Step-by-Step Guide to Export PNG from AutoCAD

Understanding the Export Process

Exporting images in AutoCAD can create high-quality visuals for presentations, documentation, or web use. The PNG format is particularly beneficial for its lossless compression and support for transparency. Follow the detailed steps below to successfully export a PNG file in AutoCAD 2025.

Setting Up the Image Size

1. Access the Export Command: Start by accessing the command line in AutoCAD. Type EXPORT or EXPORTPNG and press Enter.
2. Configure Image Dimensions: A dialog box will appear prompting you to input the desired image dimensions. For instance, if you want an image at a size of 17 inches by 11 inches at 300 DPI (dots per inch), calculate the pixel size as follows:
   • Width: 17 inches × 300 DPI = 5100 pixels
   • Height: 11 inches × 300 DPI = 3300 pixels
     Enter these dimensions into the appropriate fields and select "Next."

Naming and Saving the File

1. File Naming: After setting the image size, you will have the opportunity to name your file. Input a descriptive name such as "17x11_PNG" and click "Next."
2. Complete Export Process: Review the settings and click "Finish." You will receive a confirmation message that the export has been completed successfully. Click "OK" to finalize the process.

Making PNG Images Transparent

If you want to create a transparent PNG from your drawing:

1. Zoom into the Image: Focus closely on the image area where you need to make the color transparent.
2. Select the Image Frame: Click on the image frame to activate it.
3. Access Properties: Right-click on the image and select ‘Properties’ to open the Properties palette.
4. Set Transparency: Find the option labeled ‘Transparency Color,’ click it, and the Transparency Color dialog will open.
5. Choose a Color: Click ‘Select’ and then pick the specific color from the image that you wish to make transparent.

Standard Export from AutoCAD

To perform a standard image export:

1. Navigate to the Output Tab: Access the ‘Output’ tab within your current workspace. Choose ‘Map Data Transfer As Image.’
2. Select Image Format: In the dialog that appears, select the image format in which you would like to save the file from the "Files of Type" dropdown.
3. Specify Location: Indicate the name and storage location for the image. Click ‘Save’ to export the file.

Exporting a High-Resolution PNG

If high resolution is crucial:

1. Use the PLOT Command: Input PLOT or PAGESETUP in the command line.
2. Select Export Options: In the Plot dialog, choose either ‘PublishToWeb JPG’ or ‘PublishToWeb PNG.’
3. Choosing Resolution: Select from the default paper sizes provided, or if necessary, create a custom resolution by clicking on ‘Properties’ and setting your desired DPI for finer detail.
