What is a .SLDPRT file?
SLDPRT is a single-part 3D model from SolidWorks. Created and opened by SolidWorks.
- Did you know
- SolidWorks launched in 1995 and made 3D mechanical CAD affordable on Windows PCs.
- Under the bonnet a .sldprt is a Microsoft OLE compound document, the same structured-storage container technology used by classic .doc and .xls files.
- A part file holds one component’s feature-based history, the recipe of operations that build up its 3D solid.
- What Analyser shows you
- Open a SolidWorks part (.sldprt), assembly (.sldasm) or drawing (.slddrw). Older (pre-2015) files are OLE2 documents: Analyser reads the saved preview thumbnail and the document metadata (title, author, who last saved it and when). Files saved by SolidWorks 2015 or later are encrypted by Dassault Systemes, so they are identified but their contents cannot be read outside SolidWorks - in either case the editable Parasolid geometry stays proprietary, so export to STEP, STL or 3MF for the full 3D viewer.
- Open a .SLDPRT file
- Drag a .SLDPRT file onto the Analyser home page (or tap to pick one). It opens entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
