Convert Your 3D Mesh/Model FBX Files to ASE

Our free and fast tool will convert most 3D mesh or FBX (Autodesk Filmbox) model files to a standard ASE (Ascii Scene Export) 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 FBX files; up to 25 files at a time can be converted.

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

How to Convert your FBX to ASE Online?

Download your ASE

Click the download link once completed to receive your ASE file.

Frequently Asked Questions

How can I convert my FBX file to ASE?

First click the "Upload..." button, select your FBX file to upload. Select any configuration options. When the FBX to ASE conversion has completed, you can download your ASE file straight away.

How long does it take to convert my FBX to ASE?

We aim to process all FBX to ASE 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 FBX to ASE 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 FBX to ASE on ImageToStl.com?

Yes, of course! We do not store the FBX file you submit to us. The resulting ASE file, once created is deleted 15 minutes after upload and the download link will expire after this time.

Can I convert FBX to ASE on Windows, Linux, Android, iOS or Mac OS?

Yes! Our FBX to ASE 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 FBX conversion tool please consider white-listing our site. When an Ad Blocker is enabled there are some conversion limits on some of our tools and processing/conversion times will be longer.

What version of FBX file is supported?

Our tool can read binary FBX versions 7.0 and above and text formatted FBX files version 6.4 and above. Please ensure your FBX version meets these requirements before uploading.

I have several FBX files; can I batch convert my FBX to ASE?

Yes! Our FBX tool supports full batch conversions. You can upload up to 25 and FBX files at a time. Our tool will convert them all as quickly as possible. Once completed, you can either download the ASE files individually or download them all in a single ZIP file.

Description

The FBX format by AutoDesk was originally developed by Kaydara in the 1990s as a means to store 2D or 3D content with motion data. It has evolved over the years to become a widely used format by 3D modeling applications such as Blender, 3D Studio Max, and others due to its 3D animation capabilities.

The format is used to contain 3D models, which include vertices, faces, and other 3D geometry along with animation data. The format is proprietary; however, there is a publicly available API to use for development purposes. The file contents can be either text or binary, and work has been carried out by the Blender Foundation to document the format.

FBX Notes

If your FBX file contains texture files and other texture-related data, these will be included in the conversion process.

Description

The ASE format (Ascii Scene Export) is a plain text file format used to represent a full 3D scene. The 3ds Max software is the main supporter of ASE as an export format, though there is support within other applications such as Blender for ASE files.

An ASE file will contain 3D geometry data such as vertices, faces, normals, and other data. As the data is stored in human-readable text format, the files lend themselves to being easy to parse; however, they can become quite large when used with complex 3D scenes.

How does it work?

Converting from the FBX file format to ASE can be a complex process, and any tool used for this conversion process needs to be able to handle a variety of data conversion tasks as well as identify any defects within the 3D model and fix them. Here we will explain the conversion process used by our tool to accurately convert your FBX file to a valid ASE 3D model. Let's start with the conversion process, which involves the following steps:

Step 1: Read the Source FBX File

In its simplest form, an FBX file can be either a plain text or binary file containing 3D data such as vertices, faces, normals, and more. When combined, these make up the 3D model you see on your screen.

When our tool reads this 3D data, all we are interested in are the vertices, faces, and normals, as this is the only data that can be accurately converted into the final ASE file.

The FBX file can contain other data, such as material definitions and textures, that describe how a particular set of 3D geometry should be rendered. As we are creating an ASE file, which does not support materials and textures, we will be ignoring this data if it is present in the FBX file.

For more information regarding the FBX file format, please see this great article that goes into a lot of detail explaining the FBX format.

Step 2: Process File Data

With the FBX file data read, our tool generates an internal representation of the full 3D model and will attempt to fix any geometry issues encountered. Along with repairing any issues with the 3D model, the tool will remove any duplicated vertices and prepare the model for exporting to the ASE format.

Step 3: Saving to the ASE Format

With the conversion process entering its final stages, our tool now needs to take the in-memory 3D model we have created in step 2 and convert it to the ASE format.
