To import a DXF/DWG file into Altium Designer, use the "AutoCAD" import feature within the schematic or PCB editor.
Here's a step-by-step guide:
- Open Your Project: Open the Altium Designer project containing the schematic or PCB document where you want to import the DXF/DWG file.
- Open the Target Document: Open the specific schematic or PCB document in which you want to place the imported data.
- Navigate to the Import Command: From the main menus of the active schematic or PCB editor, go to File » Import » AutoCAD.
- Select the DXF/DWG File: The "Import File" dialog box will appear. Browse to the location of your DXF or DWG file and select it.
- Configure Import Settings (If Needed): Depending on the complexity of the DXF/DWG file and your desired outcome, you might need to adjust the import settings. These settings can typically be accessed after selecting the file, often in a subsequent dialog. Common settings might include:
- Layer Mapping: Assigning DXF/DWG layers to Altium layers.
- Units: Specifying the units used in the DXF/DWG file (e.g., millimeters, inches).
- Scaling: Adjusting the size of the imported data.
- Object Conversion: Defining how specific DXF/DWG objects (e.g., lines, arcs, text) are converted into Altium objects. Some layers might need to be converted to keepout layers or silkscreen overlays, depending on the design requirements.
- Complete the Import: After configuring the settings (if necessary), confirm your choices to proceed with the import process. Altium will convert the DXF/DWG data into Altium objects within the active document.
- Verify the Imported Data: Inspect the imported data to ensure it is correctly placed and scaled. You may need to make further adjustments to the imported objects to align them with your existing design.
Important Considerations:
- Units: Ensure the units in the DXF/DWG file are consistent with the units used in your Altium project. Incorrect unit settings can lead to scaling issues.
- Layer Mapping: Carefully map the DXF/DWG layers to appropriate Altium layers to maintain the intended organization and functionality of the imported data.
- Complexity: Complex DXF/DWG files may require more processing time and may not import perfectly. Simplifying the DXF/DWG file before importing can improve the results.
- Version Compatibility: Verify that the DXF/DWG file version is compatible with your version of Altium Designer.
