Convert DRW to SLDPRT

Understanding DRW and SLDPRT file formats

DRW files are drawing files commonly associated with CAD software such as PTC Creo (formerly Pro/ENGINEER) or DraftSight. These files typically contain 2D engineering drawings, annotations, and layout information. On the other hand, SLDPRT files are SolidWorks Part files, which store 3D part models, including geometry, features, and design history, used in SolidWorks CAD software.

Why convert DRW to SLDPRT?

Converting a DRW file to SLDPRT is often necessary when you want to use 2D drawing data as a basis for creating or editing 3D models in SolidWorks. This conversion is common in collaborative engineering environments where different CAD systems are used.

How to convert DRW to SLDPRT

Direct conversion from DRW to SLDPRT is not natively supported, as DRW files are 2D drawings and SLDPRT files are 3D models. However, you can follow these steps to achieve the conversion:

1. Export the DRW file to a neutral 2D format such as DXF or DWG using your original CAD software (e.g., PTC Creo or DraftSight). Use File → Export → DXF/DWG.
2. Import the DXF/DWG file into SolidWorks by selecting File → Open and choosing the exported file.
3. In the SolidWorks DXF/DWG Import Wizard, select Import to a new part as 2D sketch.
4. Use the imported sketch as a base to create 3D features (e.g., extrude, revolve) and save the file as SLDPRT using File → Save As → SLDPRT.

Best software for DRW to SLDPRT conversion

• PTC Creo or DraftSight for exporting DRW to DXF/DWG.
• SolidWorks for importing DXF/DWG and creating SLDPRT files.
• For batch or automated conversions, consider Autodesk AutoCAD (for DWG/DXF handling) and SolidWorks Task Scheduler (for automating imports).

Tips and considerations

• Ensure your DRW file contains clean, well-organized geometry for best results.
• Some details (like annotations or dimensions) may not transfer directly to the 3D model.
• Manual adjustments in SolidWorks may be necessary to fully define the 3D part.
