If you have stumbled upon a file with the .dft extension, you are likely dealing with a Solid Edge Draft Document. These are 2D engineering drawings commonly used in manufacturing and mechanical design.
Because Solid Edge is high-end, expensive software, not everyone has it installed. Finding a true "online" viewer for this specific proprietary format is tricky. Here is a breakdown of the best ways to view DFT files, ranging from web-based workarounds to free desktop tools.
If you are on a Windows PC, the most reliable method is to use the official free viewer provided by Siemens. Dft File Viewer Online
How to use it:
If you have a DFT file sitting on your desktop right now, follow this universal workflow to view it within two minutes. If you have stumbled upon a file with the
Step 1: Choose your platform. Navigate to ShareCAD.org or SharePLM (search "Siemens Online Viewer").
Step 2: Upload the file.
Click "Choose File" or drag your .DFT file into the browser drop zone. Note: Check the website’s privacy policy regarding file retention before uploading sensitive military/automotive designs. How to use it: If you have a
Step 3: Wait for server rendering. The cloud server slices the DFT file into tiles (similar to Google Maps for engineering). This usually takes 5 to 20 seconds depending on file complexity.
Step 4: Interact with the drawing. Once loaded, use your mouse or touchscreen to:
Step 5: Export (If needed). Most online viewers do not allow you to edit the DFT file (that requires Solid Edge), but you can usually Print to PDF or take a screenshot to share the visual information with non-engineering colleagues.
Before looking for a viewer, it is crucial to identify exactly what type of DFT file you have, as the extension is used by two very different types of software:
