You can use our AC to STL conversion tool to quickly and easily convert your 3D model files for free. You may upload up to 20 files at one time, and our batch AC to STL converter will process each 3D model and present you with a download link for each file once completed.
Or drag and drop your files here to upload.
A maximum of 20 files can be uploaded at once.
Our 3D model AC to STL tool will load your AC file and, where supported, attempt to extract all the relevant 3D features, such as geometry, textures, and animations. To access the 3D conversion configuration options, click the button when you have selected your files. The current options support the ability to voxelize your 3D model and more.
Here are two simple steps to convert your AC to STL using our fast and free AC converter tool.
First, click the "Upload..." button and select your AC file to upload. Your AC file will be uploaded to our servers. When the AC to STL conversion has completed, you can download your STL file right away.
We aim to process all AC to STL conversions as quickly as possible; this usually takes around 5 seconds; however, this can be longer for certain files, so please be patient.
We aim to provide the best conversion experience. Our tools are under constant review and development, with new features being added every week.

AC Converter Capabilities
Our AC 3D Model/Mesh tool does not support any colour material data contained within AC files, so the converted file will not contain any colour information.

The STL, or Standard Triangle Language, file format has been around since the '80s and is supported by most modern 3D modelling applications. In particular, the STL format has become something of a standard format within the area of 3D printing, despite the rise of more modern formats such as 3MF.
STL files come in two flavours: binary or text format. The text format is human-readable, making it easy to perform manual edits, but can lead to very large file sizes. As you can imagine, the binary format is much more compact and represents the majority of the STL files you are likely to encounter.
The format itself is very simple; the 3D model is represented by a sequential list of triangles, with each triangle defined with 3 points consisting of their X, Y, and Z positions, along with an additional vector that contains the face normal (the direction the face is pointing). There is an additional attribute block for each triangle; however, this is largely unused and thus unsupported.
STL Converter Capabilities
Our 3D conversion tool does not support colour or material information in STL files, so your file will not contain any colour information.
Your AC file will be converted to a STL file using our unified 3D model and mesh conversion tool. Our AC 3D tool performs accurate conversions of 3D elements such as vertices, faces, normals, and relevant material information. Our tool will not attempt to transfer any colour information if it is present in your AC file; your final 3D model will contain only geometry data.
