Convert EDRW to PRT

Understanding edrw and prt file formats

EDRW files are eDrawings files, a lightweight, read-only format developed by Dassault Systèmes for sharing 2D and 3D CAD data. These files are commonly used for viewing and markup, not for editing or direct CAD modeling.

PRT files are Part files used by various CAD software, such as Siemens NX, PTC Creo, and SolidWorks, to store 3D part models. These files contain detailed geometry, features, and design data for manufacturing and engineering purposes.

How to convert edrw to prt

Direct conversion from EDRW to PRT is not straightforward because EDRW is a viewing format and does not contain full model data. To convert, you typically need access to the original CAD file (such as SLDPRT for SolidWorks) or use a workaround by exporting to an intermediary format.

Recommended software for conversion

• SolidWorks: If you have access to the original SolidWorks file, open it in SolidWorks and use File → Save As to export as a PRT file compatible with your target CAD software.
• eDrawings Professional: Allows exporting EDRW to formats like STL or STEP, which can then be imported into CAD software and saved as PRT. Use File → Save As and select a neutral format.
• Autodesk Fusion 360: Import a neutral format (like STEP) and then export as a PRT file if supported.

Step-by-step conversion process

1. Open the EDRW file in eDrawings Professional.
2. Go to File → Save As and choose a neutral format such as STEP (.step, .stp) or IGES (.igs).
3. Open the exported file in your CAD software (e.g., SolidWorks, Siemens NX, or PTC Creo).
4. Save or export the file as a PRT file using File → Save As and selecting the appropriate PRT format.

Important considerations

• EDRW files do not contain full model data, so some features may be lost during conversion.
• Always try to obtain the original CAD file for best results.
• Neutral formats like STEP or IGES are widely supported for interoperability.
