Convert Your 3D Mesh/Model KMZ Files to STEP

Our free and fast tool will convert most 3D mesh or KMZ (Keyhole Markup Language) 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 KMZ files; up to 25 files at a time can be converted.

To convert your KMZ 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 KMZ to STEP conversion process, see the conversion information section below.

Description

A KMZ, which is short for Keyhole Markup Zip, is a compressed ZIP file used to contain geographic data, including 3D models, images, and terrain.

The KMZ format comprises a single KML file containing XML data and supporting assets such as images and 3D models using the Collada DAE format, all contained within a compressed ZIP format. There are several specialist map-rendering applications that can open KMZ files.

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

Step 1: Read the Source KMZ File

In its simplest form, an KMZ file is a binary data file containing 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 KMZ file format, please see this great article that goes into a lot of detail explaining the KMZ format.

Step 2: Process File Data

With the KMZ 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 KMZ file to STEP?

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

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

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

Yes, of course! We do not store the KMZ 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 KMZ to STEP converter?

No. All our conversion tools process your KMZ 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 KMZ to STEP on Windows, Linux, Android, iOS or Mac OS?

Yes! Our KMZ 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 KMZ 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 KMZ to STEP?

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