Convert DRW to PART

Understanding DRW and PART file formats

DRW files are drawing files commonly associated with CAD (Computer-Aided Design) software such as Solid Edge, CorelDRAW, or DraftSight. These files typically contain 2D or 3D vector graphics, technical drawings, or schematics. The specific structure and compatibility of a DRW file depend on the originating software.

PART files, on the other hand, are usually associated with SolidWorks and represent 3D part models. These files store detailed information about a single component, including geometry, features, and material properties, and are essential for 3D modeling and manufacturing workflows.

Why convert DRW to PART?

Converting a DRW file to a PART file is often necessary when you want to transform a 2D drawing or schematic into a 3D model for further design, simulation, or manufacturing in SolidWorks or compatible CAD software. This process enables engineers and designers to leverage existing drawings for 3D modeling, saving time and reducing errors.

How to convert DRW to PART

The conversion process typically involves importing the DRW file into a CAD program that supports both formats, then using built-in tools to create a 3D part from the 2D drawing. Here’s a general workflow using SolidWorks:

1. Open SolidWorks.
2. Go to File → Open and select your DRW file. If the file is from another CAD system, you may need to use the appropriate import options.
3. Once the drawing is open, use the Insert → DXF/DWG tool if necessary to import 2D geometry.
4. Use the Convert Entities tool to transfer 2D sketches onto a new part file.
5. Switch to a new part document (File → New → Part), and paste or recreate the sketch.
6. Use features like Extrude, Revolve, or Loft to create a 3D model from the 2D sketch.
7. Save the file as a .SLDPRT (SolidWorks Part) file using File → Save As.

Best software for DRW to PART conversion

• SolidWorks: The most reliable choice for converting DRW to PART, especially for engineering and manufacturing workflows.
• Autodesk Inventor: Can import certain DRW files and export to part formats, though compatibility may vary.
• FreeCAD: An open-source alternative that supports various CAD formats, though conversion may require additional steps.
• Online converters: Some online tools claim to convert DRW to PART, but results may be inconsistent and security should be considered.

Tips for successful conversion

• Ensure your DRW file is compatible with the target CAD software.
• Clean up the 2D drawing before importing to avoid errors in the 3D model.
• Check for lost or misaligned geometry after import and before creating the 3D part.
