What is a CDW file

CDW files mostly belong to KOMPAS-3D. CDW files are used to store 3D design data in CAD applications, particularly with KOMPAS-3D systems. They often use a ZIP-based structure to bundle drawing elements such as vectors, layers, and metadata.

File Structure: The ZIP container organizes multiple parts of a single drawing.

Data Content: Contains detailed 3D design information and technical drawing data.

Usage: Serves as the native format for CAD drawings in KOMPAS-3D.

Access: Best viewed and edited using KOMPAS-3D or compatible CAD viewers.

FilExt.com tips: Some files are also described as traditional CAD drawing file formats. It is possible to extract and inspect the internal contents with ZIP tools if needed. For further details, visit this webpage.

How can I open a CDW file?

You need a suitable software like KOMPAS-3D to open a CDW file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your CDW file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a CDW file directly in the browser:. Just drag the file onto this browser window and drop it.

CDW format details:

To view or edit CDW files you need to know the file format, because it determines how the data in this file is stored. The initial characters of a file are called signature, sometimes also referred to as "magic bytes". The signature can be used to infer the file format. File extension, signature and file format must match; otherwise errors will occur when the file is opened. So you need a detailed analysis of a file to find out the format and the associated program. Below is our analysis of the CDW files:

The CDW extension is quite commonly used. The file itself is used by different programs with different formats. But the following two file formats are common:

• 50% of all CDW files internally use the ZIP format, so several files are combined and compressed into one CDW file. Primarily 5 to 10 files are included. File names inside are Contents, FileInfo, MetaInfo, MetaProductInfo, Options.xml, Preview, SysInfo, details, images and resourcesInfo. A little tip: If you rename the file extension to .zip and then double-click, you will see the included files and images. CDW files can be up to 12 MB in size, but are often around 46 KB - 170 KB. The following keywords are characteristic: AppName, FileInfo, [FileInfo], AppVersion=KOMPA and -3D V16. Files like these are about chertezh and skhema.
• 45% of all CDW files are KOMPAS Drawing files. They consist of unreadable binary data. The files are 52 KB to 540 KB in size, with a median of 130 KB. Certain words are almost always found in the files, such as DbQ8, HdR9$ and DOCUMENT_IMAGE.

All the rest of the CDW files (5%) have different formats. These files are often connected to plan or tgtu. You can get all the details of your CDW file by dragging it onto this page or by clicking the button "Choose your .cdw file to analyze" above.
