Convert Your BREP CAD Files to STL

Our free and fast tool will convert most BREP (Boundary representation) CAD files to a standard STL (Standard Triangle Language) 3D model file that can then be edited further in most popular 3D editing packages such as Blender or 3D printed without any further processing. Our conversion tool can also batch convert multiple BREP files; up to 200 files at a time can be converted.

To convert your BREP file, click the Upload button above and select the file to convert. Once selected, the file will be converted to a STL file and will be ready for download shortly afterwards. For more information about the BREP to STL conversion process, see the conversion information section below.

Description

A BREP file (or boundary representation) is a file used in CAD applications to store a shape that consists of vertices to define the points and faces and edges to create the final shape.

Commonly found as an option for importing into CAD applications, BREP is a well-supported and easy-to-use format for transferring data between different CAD applications.

Description

The STL file format has its roots in the 1980's and is the native file format for 3D Systems stereolithography CAD software. The format defines a triangulated mesh with vertices and faces and is a popular format for sharing 3D printable model files.

There were several formats that attempted to extend the STL format, namely SolidView and VisCAM, whose formats included limited 15-bit color information for each mesh face, which is often ignored by most modern 3D software. The STL format can be either text or binary; our tools will support both formats.

STL Notes

The standard STL file format does not support colored faces, vertices, or texture information. The STL file generated by the tool will contain only raw mesh/triangle data by default, which is perfect for 3D printing.

The tool also has the option to save the file to one of the non-standard formats that support colored faces, such as VisCAM and SolidView which is perfect if you want to further process the STL in software that supports these formats.

Supported Features

Mesh geometry
Face colors via the VisCAM and SolidView formats
Binary and text versions are supported

Frequently Asked Questions

What is an STL file?

The STL file format describes an unstructured triangulated surface of the triangles using a 3D Cartesian coordinate system. STL files do not contain any scale information, and the units are arbitrary. We have a more detailed description of an STL file which can be found on our STL file page.

What STL formats can I convert to?

Our tool will save all STL files in binary format. Optionally, our tool will allow you to save to the non-standard color STL format.

I have several BREP files; can I batch convert my BREP to STL?

Yes! Our BREP tool supports full batch conversions. You can upload up to 200 BREP files at a time. Our tool will convert them all as quickly as possible. Once completed, you can either download the STL files individually or download them all in a single ZIP file.

How can I convert my BREP file to STL?

First click the "Upload..." button, and select your BREP file to upload. You can also drag and drop your file onto the tool. Once your file is selected, you can set any configuration options. When the BREP to STL conversion has completed, you can download your STL file straight away.

How long does it take to convert my BREP to STL?

We aim to process all BREP to STL conversions as quickly as possible, this usually takes around 5 seconds but can be more for larger more complex files so please be patient.

How accurate is the BREP to STL conversion?

We aim to create the most accurate conversions with our tools. Our tools are under constant development with new features and improvements being added every week.

Is it safe to convert my BREP to STL on ImageToStl.com?

Yes, of course! We do not store the BREP file you submit to us. The resulting STL file, once created, is stored for 4 hours after upload; after this time it is deleted, and the short-term download link will stop working. You can create a long-term download Url with most tools that will ensure the file is retained for 24 hours, allowing you to download the file when convenient. Our tools also come with a Delete button, allowing you to delete the file immediately.

Do I need a high-spec. computer to use the BREP to STL converter?

No. All our conversion tools process your BREP file on our dedicated conversion servers, meaning you can use our tools on low-spec computers, laptops, tablets, and mobile devices and receive your converted STL file quickly.

Can I convert my BREP to STL on Windows, Linux, Android, iOS or Mac OS?

Yes! Our BREP to STL tool will run on any system with a modern web browser. No specialist software is needed to run any of our conversion tools.

What if I am using an Ad Blocker, will that affect things?

Yes. Although you can use an Ad Blocker, if you like our BREP conversion tool please consider white-listing our website. When an Ad Blocker is enabled there are some conversion limits and some settings may not be available when using our tools. Processing/conversion and download times will also be longer.

Can I get support with converting my BREP to STL?

Yes. When you have converted your BREP to STL, there is a "Feedback" option that you can use to let us know of any issues you encountered when converting your file.
