All about A3D Files
The A3D file type is primarily associated with Amapi.
What is an A3D file?
A3D files mostly belong to Amapi by Eovia. The A3D file extension is primarily associated with Evio's legacy 3D modelling software known as Amapi. The models in such A3D files usually comprised both static and dynamic 3D forms like architectural design, home/office furniture design, prototypes of industrial machinery, and simulations. Users could also develop and store games with interactive 3D graphics using the A3D format. Another major association of the A3D file extension is the Alternativa3D export file used to export 3D models from the web hosted version of AlternativaPlayer onto a local machine. By convention, the entry point to the exported models is the defaultModel.ad3 file located in the model folder of the exported zip file.
How to open an A3D file
You need a suitable software like Amapi from Eovia to open an A3D 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 A3D file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a A3D file directly in the browser:. Just drag the file onto this browser window and drop it.

A3D file format details:
To find out what program is needed to open A3D files, you need to determine the file format. The first characters in a file identify the file format, for example, HTML files start with the bytes <html>. Nonetheless, different programs can utilize the same file extension to represent distinct file formats. Double-clicking on the file often results in an error when opening. If there are problems opening a file, you must first determine the file format used. In the following you will find our evaluation of the A3D files:
A3D is not a commonly used file extension and includes various formats for various programs. However, the following two file formats are common:
- 25% of all A3D files use ZIP compression, so several files are compressed and saved in one A3D file. Primarily 5 to 9 files are included. File names are e.g. Contents, FileInfo, MetaInfo, MetaProductInfo, Preview, SysInfo, details, images and resourcesInfo. You can see the included files and images by renaming the file extension to .zip and then double-clicking it. The files are on average 270 KB in size and range from 51 KB to 1 MB. The files contain the following words: AppName, FileInfo, [FileInfo], AppVersion=KOMPA and -3D v18.
- 20% of all A3D files start with the bytes I-code MS , which are crucial for this file format. These are binary files, so they do not contain words or text. The average file size is 150 KB with most files being between 32 KB and 830 KB in size. The files contain the following words: "Report window, Bridges, Calc text, Dimension round, Long text, Long text cont, NCompressed image, Report File #, Report text desc, Subtype, Dim R/, suf and I-code MS U. A common filename is ArtiosCAD_3D.A3D. Files like these are sometimes connected to artioscad.
The remaining 55% of all A3D files are different files with different signatures, such as Glview. Files like these are sometimes linked to tile. If you want to find out what your A3D file contains, drag and drop it onto this page.
