Convert Your 3D Mesh/Model ASE Files to STEP

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

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

How to Convert your ASE to STEP Online?

Here are two simple steps to convert your ASE to STEP.

Upload a ASE

Click the "Upload a ASE File" button and select a ASE to upload. The maximum file size is 100MB.

Download your STEP

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

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.

Description

The STEP file format is a 3D format defined in 1994 and used to store 3D objects for use in computer-aided design (CAD) applications. STEP files are text-based, formatted files containing one command per line, with a full 3D model comprising of many commands.

Although STEP files are widely supported by most CAD applications, the format does have its limitations, such as the necessity to read the complete file into memory in order to parse the contents, and due to the textual storage of information, the files can be quite large and time-consuming to process.

How does it work?

Converting from the ASE file format to STEP 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 ASE file to a valid STEP 3D model. Let's start with the conversion process, which involves the following steps:

Step 1: Read the Source ASE File

In its simplest form, an ASE file is a plain text file containing human-readable 3D data such as vertices, faces, normals, and more. When combined, these make up the 3D model you see on your screen.

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

Step 2: Process File Data

With the ASE 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 STEP format.

Step 3: Saving to the STEP 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 STEP format.

Frequently Asked Questions

How can I convert my ASE file to STEP?

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

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

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

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

Do I need a high-spec. computer to use the ASE to STEP converter?

No. All our conversion tools process your ASE 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 STEP file quickly.

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

Yes! Our ASE to STEP 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 ASE 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.

Can I get support with converting my ASE to STEP?

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