A SLDPRT file is a SOLIDWORKS Part file, which is the native file format used by SOLIDWORKS to save one individual 3D component. The name can be understood as SolidWorks Part, where "SLD" refers to SOLIDWORKS and "PRT" refers to part. A part is one separate object within a design, such as a bolt, gear, bracket, pipe fitting, plastic casing, machine plate, wheel rim, engine cover, or any single component used in a larger product or mechanical system. This makes a SLDPRT file different from a SLDASM file, which is an assembly file made up of multiple parts, and a SLDDRW file, which is used for technical drawings or blueprints.
A SLDPRT file is not just a simple 3D image or preview. It can contain detailed and editable CAD information, including the part’s 3D geometry, dimensions, sketches, features, materials, appearance, and design history.

The 3D geometry includes the visible shape of the object, such as its surfaces, edges, faces, holes, curves, thickness, and overall form. The dimensions control the exact measurements of the part, such as length, width, height, diameter, radius, wall thickness, hole spacing, and angles. These dimensions are important because they allow the part to be edited accurately; for example, changing a hole diameter or part thickness can update the model without redrawing the entire object.
The file may also contain sketches, which are the 2D drawings used as the starting point for creating the 3D model. A designer might begin with a rectangle, circle, slot, or custom profile, then turn that sketch into a 3D shape using tools like extrusion, revolve, or cutting. These modeling steps are stored as features, such as extrude, cut, fillet, chamfer, shell, pattern, hole wizard, and revolve. SOLIDWORKS usually keeps these features in a design history or feature tree, allowing the designer to go back and modify earlier steps. This is one reason SLDPRT files are very useful in engineering and manufacturing, because they remain editable rather than being treated as fixed shapes.
A SLDPRT file can also store material and appearance information. The material may define whether the part is made from steel, aluminum, plastic, rubber, wood, or another material, which can affect calculations such as weight, density, strength, and simulation results. The appearance controls how the part looks on screen, including color, texture, transparency, shine, or surface finish. For example, a metal bracket may appear silver, a plastic cover may be black, and a transparent part may look like glass.
In a typical SOLIDWORKS workflow, a SLDPRT file is first created as an individual part. It can then be inserted into a SLDASM assembly file, where it is combined with other parts to form a complete machine, product, or structure. The same part can also be used to create a SLDDRW drawing file, which shows technical views, dimensions, notes, and manufacturing details. This allows one part file to be reused in different stages of design, documentation, testing, and production.
You can open a SLDPRT file using SOLIDWORKS, which is the most reliable program for this file type because it can usually preserve the editable design data. Other CAD programs and viewers, such as eDrawings Viewer, Autodesk Fusion, FreeCAD, or online CAD viewers, may also open or import SLDPRT files, but compatibility can vary. Some programs may only show the final 3D shape and may not preserve the original sketches, features, or design history. Also, if the file was created in a newer version of SOLIDWORKS, it may not open correctly in an older version. In that case, the file may need to be opened with a newer SOLIDWORKS version or exported into a more universal CAD format such as STEP, IGES, or STL.
Overall, a SLDPRT file is the digital 3D model of one SOLIDWORKS part. It is commonly used in mechanical design, product modeling, manufacturing, 3D printing, CNC machining, mold design, engineering documentation, and prototyping. It allows designers and engineers to create accurate parts, revise measurements, test fit and function, prepare drawings, combine parts into assemblies, and send models for production. In simple terms, a SLDPRT file is one detailed and editable building block of a larger design.
