File with STEP extension contains 3D CAD object data saved in text format that conforms to ISO 10303-21 standard, also know as Standard for The Exchange of Product Data - STEP. The format was developed as a standardized data sharing format for CAD and CAM applications and platforms. STEP file is divided into parts or section, such as:
STEP standard was developed in 1994 roku by ISO, and the latest version is designated as version 3. Third version supports references to external resources, data sharing using compressed archives based on ZIP algorithm, UTF-8 encoding, and use of digital signatures. STEP files can be opened using a text editor as its syntax is to a certain extent human-readable. STEP files also use extensions such as STP and P21.
The list that follows enumerates programs compatible with STEP files, divided into 7 categories based on operating system on which they are available. Files with STEP suffix can be copied to any mobile device or system platform, but it may not be possible to open them properly on target system.
Being unable to open files with STEP extension can be have various origins. On the bright side, the most encountered issues pertaining to STEP 3D Model files aren’t complex. In most cases they can be addressed swiftly and effectively without assistance from a specialist. We have prepared a listing of which will help you resolve your problems with STEP files.
The most common reason for such problems is the lack of proper applications that supports STEP files installed on the system. The most obvious solution is to download and install SolidWorks or one to the listed programs: TurboCAD, Fusion 360. The full list of programs grouped by operating systems can be found above. The safest method of downloading SolidWorks installed is by going to developer’s website (SolidWorks Corporation) and downloading the software using provided links.
If you already have SolidWorks installed on your systems and STEP files are still not opened properly, check if you have the latest version of the software. It may also happen that software creators by updating their applications add compatibility with other, newer file formats. The reason that SolidWorks cannot handle files with STEP may be that the software is outdated. The most recent version of SolidWorks is backward compatible and can handle file formats supported by older versions of the software.
If you have the latest version of SolidWorks installed and the problem persists, select it as the default program to be used to manage STEP on your device. The method is quite simple and varies little across operating systems.
Change the default application in Windows
Change the default application in Mac OS
If you followed the instructions form the previous steps yet the issue is still not solved, you should verify the STEP file in question. It is probable that the file is corrupted and thus cannot be accessed.
If the STEP is indeed infected, it is possible that the malware is blocking it from opening. It is advised to scan the system for viruses and malware as soon as possible or use an online antivirus scanner. STEP file is infected with malware? Follow the steps suggested by your antivirus software.
If the STEP file was sent to you by someone else, ask this person to resend the file to you. The file might have been copied erroneously and the data lost integrity, which precludes from accessing the file. If the STEP file has been downloaded from the internet only partially, try to redownload it.
Some files require elevated access rights to open them. Switch to an account that has required privileges and try opening the STEP 3D Model file again.
If the systems has insufficient resources to open STEP files, try closing all currently running applications and try again.
Regularly updated system, drivers, and programs keep your computer secure. This may also prevent problems with STEP 3D Model files. Outdated drivers or software may have caused the inability to use a peripheral device needed to handle STEP files.
