Many engineers and students are faced with the need to urgently view or edit a three-dimensional model while away from a desktop computer. A logical question arises: how to open KOMPAS-3D on Android for quick access to the project? It is important to immediately set the record straight: there is no full-fledged native version of this computer-aided design system for mobile operating systems. The architecture i: There is no full-fledged native version of this computer-aided design system for mobile operating systems. Architecture Android and computing power of smartphones do not yet allow running heavy CAD kernels directly.
However, this does not mean that you will be left without access to your drawings. Developers from ASCON and third-party companies offer a number of effective workarounds. You can use cloud servicesspecialized viewers or remote access tools. In this article we will analyze in detail all the available ways to interact with files of the format .m3d i .a3d on your device.
The modern mobile application market offers flexible solutions for engineers. From simple geometry viewing to full editing via remote desktop, the choice depends on your specific needs. Next, we will look at the technical nuances of each method so that you can choose the best option for your work in the field.
Official solutions from the developer ASCON
ASCON, the developer of the system KOMPAS-3D, understands the needs of mobile users. In response to demand, specialized applications were released that allow you to work with system data on tablets and smartphones. The main tool here is the application KOMPAS-3D Viewer. It is intended exclusively for viewing models and drawings without the ability to deeply edit them or create new geometry from scratch.
The functionality of the viewer is wide enough for control and presentation tasks. The user can rotate the model, zoom in on individual nodes, measure distances between points, and even make cross-sections. Work with associative views is supported, which is critical for reading design documentation. The interface is adapted for touch control, allowing you to conveniently manipulate a three-dimensional scene fingers.
⚠️ Attention: The KOMPAS-3D Viewer application does not allow saving changes to source files. This is a tool for reading and analyzing geometry only.
To run the application, you will need a model file saved in a compatible format. Most often these are the system’s own formats or universal exchange standards. It is important to ensure that the version of the viewer on your device matches or is newer than the CAD version in which the file was created to avoid errors in displaying complex surfaces.
Before installing the viewer, check the availability of free space on the device - some complex assemblies may require a significant amount of RAM for smooth rotation.
Preparing files for mobile viewing
To open a project on your phone, it is not enough to simply copy the file from your computer. Often, preliminary conversion or export of data into a format understandable by a mobile application is required. Standard files .m3d may not open directly in third-party apps without special plugins or converters. Therefore, the preparation stage is key in the mobile engineering chain.
It is recommended to use the format PDF 3D or STEP for data transfer. The PDF 3D format is especially convenient because it allows you to embed a 3D model directly into the documentation, which can be opened with any modern reader on Android. To export to KOMPAS-3D on a PC, you must use the save menu and select the appropriate file type in the drop-down list.
- 📂 Use the STEP format to transfer pure geometry without construction history.
- 📄 Export to PDF 3D if you need to save views and specifications along with the model.
- 💾 Compress RAR or ZIP archives before sending if the assembly file is larger than 50 MB.
After exporting, the file must be transferred to the device. This can be done via cloud storage, instant messenger or USB cable. When transferring via instant messengers, make sure that the file is sent as documentand not as a media file to avoid losing data or changing the extension.
☑️ Preparing the model for viewing
Third-party viewers and universal viewers
If the official application for some reason does not suit you, the store Google Play offers many alternatives. There are universal CAD viewers that can open files from various design systems. Among the popular solutions are applications that support the .stp, .igs and .xtformats. These apps often have a lighter interface and run faster on budget smartphones.
However, when using third-party software, it is worth considering the risks of losing display accuracy. Complex mates, specific size fonts, or unique material designations may not display correctly. Universal viewers sacrifice detail for speed and compatibility with multiple formats. They are ideal for quickly estimating dimensions, but for accepting critical components it is better to use native software.
Some advanced applications allow you not only to view, but also to perform basic measurements. You can check the hole diameter or cut length directly on your phone screen. This is useful when purchasing materials or monitoring the dimensions of a workpiece in the workshop, when there is no computer with installed KOMPAS-3D.
| Application name | Supported formats | Measurement capability | Price |
|---|---|---|---|
| KOMPAS-3D Viewer | m3d, a3d, kdw | Yes | Free |
| CAD Assistant | STEP, IGES, BREP | Yes | Free |
| eDrawings | SLDPRT, STEP, IGES | Yes | There are paid features |
| AutoCAD Mobile | DWG, DXF | Yes | Subscription |
Use of cloud services and web versions
With the development of technology, it became possible to work with heavy CAD systems through a browser. Cloud platforms allow you to run a lightweight version of the design system directly in your mobile browser window. To do this, you don’t need to install anything; you just need to have a stable Internet connection and an account in the appropriate service. This solves the problem of the lack of computing power of the smartphone itself.
Services like Cloud BIM or specialized web interfaces from ASCON allow you to upload models to the server and open them from any device. All graphics processing takes place on a remote server, and the finished image is broadcast to the phone screen. This approach ensures high performance even on older phone models, since the load falls on the cloud infrastructure. Working through the cloud has its own characteristics. You will need constant access to the network, since the offline mode in such services is often limited or non-existent. In addition, the response speed of the interface will directly depend on the quality of your mobile connection. If the signal is poor, the rotation of the model may occur with delays. cloud infrastructure.

⚠️ Attention: When working in the cloud, make sure that your connection is secure, especially if you are uploading confidential drawings to third-party servers.
To get started, you usually just need to go to the service website, log in and upload the file through the browser interface. Some platforms allow you to receive direct viewing links that you can send to colleagues. This simplifies the process of approving documentation, since the recipient does not need to install special software.
Remote access to a work PC
The most powerful way to open KOMPAS-3D on Android is to connect to your home or office computer remotely. Using apps like TeamViewer, AnyDesk or RDP, you turn your smartphone screen into a monitor for a powerful workstation. In this case, only the remote control client runs on the phone, and all the hard work of building models is done by the processor of your PC.
This method gives you 100% of the functionality of the desktop version of the app. You can not only watch, but also edit, create new parts and assemble components. The only limitation is ease of control. It is difficult to operate a mouse and keyboard via a touch screen, so this method is better suited for making minor edits or demonstrating a model to a customer.
Setting up RDP access:1. Enable remote desktop in Windows settings.
2. Find out the IP address of the computer on the local network.
3. Install the Microsoft Remote Desktop app on Android.
4. Enter your IP and account information to connect.
The quality of the picture and the response speed depend on the channel bandwidth. For comfortable work with 3D graphics, it is recommended to use a Wi-Fi connection rather than mobile data. Setting up graphics compression in the remote access client will help reduce delays when transferring images of complex scenes.
Why can remote access be slow?
Delays arise due to the need to transfer a high-resolution video stream from a PC to a phone in real time. With complex geometry and rapid rotation of the model, the volume of transmitted data increases sharply, which can overload the communication channel.
Comparison of methods and selection of the optimal solution
The choice of how to open files depends on your goals. If you just need to show the model to the client or check the dimensions in the workshop, it is enough mobile viewer. It's fast, offline and doesn't require internet. If there is serious work to be done on changing the design, then you cannot do without remote access or a powerful tablet with Windows.
Let's consider the key selection criteria. Autonomy of work is important for traveling to sites where there is no stable connection. In such cases, a locally installed application is the only option. For office work or work from home, cloud solutions and remote access provide maximum flexibility and power.
- 🚀 Launch speed: Local applications start instantly, cloud applications require the Internet.
- 🛠 Functionality: Remote access provides 100% of the capabilities, viewers - only viewing.
- 🔋 Power consumption: Heavy 3D scenes quickly drain your phone's battery when rendering locally.
Don't forget about data security. Storing drawings in the cloud requires trusting the service provider, while browsing locally ensures the files don't leave your device. Assess the risks of information leakage before choosing a method for transferring data to a mobile device.
For one-time viewing tasks, use official viewers, and for full-fledged work, organize remote access to a powerful PC.
Frequently asked questions (FAQ)
Is it possible to install the full version of KOMPAS-3D on tablet with Android?
