How to open SM3 file?

The main problem with DataCAD Symbol is that the SM3 file is incorrectly associated with programs. This is manifested by the fact that SM3 files open in unusual applications or do not have an assigned program. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the SM3 file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install DataCAD

An often overlooked issue is to make sure that DataCAD is installed on the computer. To do this, enter the name DataCAD into the system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Below you will find a list of applications that support SM3 files.

Programs to open SM3 file

Remember to download programs supporting SM3 files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of DataCAD with SM3 files

If the application is or has been freshly installed, but the SM3 file still does not use the DataCAD program, it means no association. This option is available from the level of Properties of a specific file available in the context menu. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can select the desired program. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. Checking the "Always use the selected program ..." box will permanently associate the SM3 file with the DataCAD program.

Step 3. Update DataCAD to the latest version

If, however, after binding DataCAD with DataCAD Symbol there were still problems, you should update the program to the latest version. This can be done using the application (if it provides such options) or from the DATACAD LLC. website and install the latest version.

Step 4. Check for the following problems with the SM3 file

If the above steps do not help, you can assume that the file itself is not correct. File problems can be divided into the following:

The SM3 file may be unusually small compared to the original file. This is most often caused by a problem while downloading the SM3 file. The only repair option is to download the file again.
The computer may have fallen victim to a computer virus or hacker. A quick virus scan using an up-to-date antivirus program should clear up any doubts. If this is not possible, you can use the online scanner. For the best results, we will scan the entire operating system, not just our SM3 file. As a result of the scan, sometimes it is not possible to recover SM3 files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
This can happen especially when the program is dynamically developed and the structure of the SM3 files changes over time. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for the failure. Repairing is very dependent on the file type. Some programs offer the ability to automatically repair SM3 file corruption. The easiest way to restore the file is from a backup or by contacting DATACAD LLC., but this one can be expensive. Not all damage can be reversed.
When reading, a message appears that the file was encrypted or corrupted. The encrypted SM3 files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. While there is usually no problem reading such a file, it may not be possible to save it. It is best to move SM3 to a different directory.
This problem usually affects more complex files. Some file types can only be opened in one program at a time. Closing other programs should help. Sometimes it is necessary to wait a while before referencing the SM3 file again. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If this does not work either, restart the device.
