Saving an AutoCAD File in a Lower Version
To achieve compatibility with earlier AutoCAD versions, follow these detailed instructions to save a file in a lower version.
Step 1: Use the Command Line
Begin by opening your AutoCAD 2025 application. Once the program is running, locate the command line at the bottom of the interface. Type the command SAVEAS and press Enter. This initiates the Save As dialog.
Step 2: Access Save As Dialog
After entering the SAVEAS command, the Save As dialog box will appear. This window lets you specify various options for saving your file.
Step 3: Choose the File Type
In the Save As dialog, look for the "Files of Type" dropdown menu typically found near the bottom of the window. Click on this dropdown to see a list of available file formats. Select the appropriate earlier version of the DWG format you wish to save your file as. Make sure to choose a format that will ensure compatibility with the version you desire.
Step 4: Save the File
After selecting the file type, navigate to the location where you want to save the file. Enter a name for your file in the "File Name" field, and confirm by clicking the Save button. Your drawing is now saved in the chosen lower version format.
Alternative Method: Changing Compatibility Settings
If you want to convert your files to a lower version outside the standard Save As process, you can use compatibility tools:
- Go to the menu and select
Tools, then navigate toUtility. - Find and double-click on the option labeled “Downward Compatibility.”
- Select the file you wish to convert and choose the desired target version from the drop-down menu at the top.
- Specify the target folder where the converted file will be saved, and then click
Runto complete the conversion.
