How to convert stl to stp file
- 3D modeling
- No ratings yet.
Both STL and STEP formats are fairly common CAD/3D model formats and well-supported in many programs. So you should have no trouble to find a program capable of stl to stp conversion. Many 3D modeling tools or converters can be used for it as it should not be difficult to actually convert stl to stp.

Understanding STL and STP file formats
STL (Stereolithography) is a widely used file format in 3D printing and computer-aided design (CAD) that represents the surface geometry of a 3D object without any color, texture, or other attributes. It is primarily used for 3D printing and rapid prototyping.
STP (Standard for the Exchange of Product model data), also known as STEP (Standard for the Exchange of Product model data), is a comprehensive file format used for representing 3D objects in CAD software. It includes detailed information about the geometry, topology, and other attributes of the 3D model, making it ideal for complex engineering and manufacturing processes.
Why convert STL to STP?
Converting an STL file to an STP file is often necessary when you need to include more detailed information about a 3D model, such as its dimensions, materials, and other attributes, which are not supported by the STL format. This conversion is essential for engineering, manufacturing, and collaborative design processes where detailed model data is required.
Best software for STL to STP conversion
Several software options are available for converting STL files to STP files. Here are some of the best:
- FreeCAD: An open-source parametric 3D CAD modeler that supports a wide range of file formats. To convert, use File → Import to open the STL file, then File → Export to save it as an STP file.
- Autodesk Fusion 360: A powerful CAD tool that offers STL to STP conversion. Import the STL file, then use File → Export to save it as an STP file.
- SolidWorks: A professional CAD software that allows for easy conversion between different file formats. Open the STL file and use File → Save As to export it as an STP file.
Steps to convert STL to STP using FreeCAD
- Open FreeCAD and go to File → Import to load your STL file.
- Once the file is imported, navigate to Part workbench.
- Select the imported mesh and use Part → Create shape from mesh.
- Convert the shape to a solid using Part → Convert to solid.
- Finally, export the solid as an STP file using File → Export.

Frequently asked questions
Is the STL to STP converter free?
Yes, converting STL to STP on 101convert.com is completely free. No registration, email address or installation is required. If you need a higher file size limit or want to convert more files at once, see our plans.
How large can my STL file be?
You can upload STL files up to 500 MB and convert up to 5 files at once in a single batch.
What happens to my uploaded files?
Files are processed automatically and deleted from our servers within a few minutes after conversion. We never view or share your files.
Do I need to install any software to convert STL to STP?
No. The STL to STP conversion runs entirely online in your browser and works on Windows, Mac, Linux, Android and iPhone.
Did the conversion fail?
In most cases, the cause is an incorrect file format. Please upload a valid STL file for this STL to STP conversion. Occasionally, the issue may be on our side. We analyze recurring conversion failures and disable or fix the converter if we detect a defect.
