Extract text from SolidWorks library feature parts (SLDLFP)
To convert SLDLFP library feature parts to another format, you need SolidWorks or other Cad software.
To convert other file formats to the "CAD Library Feature Part" file type, you need software like SolidWorks or a similar tool.
An .SLDLFP file is a SolidWorks Library Feature Part, heavily utilized by mechanical engineers and designers to store and reuse common 3D features (like complex cuts or holes) or 2D structural sketches known as weldment profiles. Created by Dassault Systèmes, it speeds up CAD workflows by eliminating the need to redraw repetitive geometry.
However, this file format is heavily restricted by its proprietary nature. Under the hood, it relies on an OLE2 Microsoft Compound container structure that is entirely locked into the SolidWorks ecosystem. Users attempting to share these profiles with colleagues using different CAD software, like AutoCAD or Fusion 360, will quickly realize the files are completely unreadable outside of SolidWorks. You must have an active - and often expensive - software license just to see the geometry.
To bypass these frustrating vendor lock-ins, you must convert the .SLDLFP file. For cross-platform 3D interoperability, converting to universally accepted formats like STEP (Standard for the Exchange of Product model data) or IGES is highly recommended. These formats strip away the proprietary feature history but preserve the core geometry for use in almost any modern CAD tool. If you simply want to remove the "library feature" behavior and use it as a standard model, converting it to an SLDPRT is the best approach.
Converting an .SLDLFP natively requires SolidWorks, and standard online tools routinely fail because they cannot interpret the proprietary parametric data streams. If our analysis detects a supported underlying format, we can help you extract the data without installing heavy CAD suites.
Convert.Guru analyzes your SLDLFP file, detects the exact format, and lets you read the text inside.
Users also converted DWG, SLDPRT, STL and PRT files.
If you want to convert SLDLFP file to DWG, DXF, DGN, RVT, RFA, SKP, 3DM, STEP, IGES, SAT, X_T or X_B, you can use SolidWorks or similar software from the "Reusable CAD Feature Storage" category. In the File menu, look for Save As… or Export….
To convert SLDASM, DGN, PRT, IAM, X_B, CATPRODUCT, SLDPRT, RVT, ASM, DWG, CATPART or DXF files to SLDLFP, try SolidWorks or another comparable tool in the "Reusable CAD Feature Storage" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our SLDLFP converter.
