STL Troubleshooting

Common Problems Opening STL Files

Creo Parametric 3D Modeling Software Isn't There

Double-clicking your STL file prompts the message "- Can't Open STL File". Usually, this is because you do not have Creo Parametric 3D Modeling Software for - installed. This will prevent you from double-clicking to open the STL file because the OS doesn’t know how to handle it.

Tip: Another STL-related program can be selected to open the file by clicking "Show Apps" and finding the application.

Incorrect Creo Parametric 3D Modeling Software Version

In other instances, your Stereolithography File file version may not be supported by your version of Creo Parametric 3D Modeling Software. If you do not have the proper version Creo Parametric 3D Modeling Software (or any of the other programs listed above), you may need to try downloading a different version of it, or one of the other software applications listed above. The primary cause of this problem is that your Stereolithography File file was created by a different (newer) version of Creo Parametric 3D Modeling Software than what's installed.

Tip: Sometimes you can get a clue about the version of STL file you have by right clicking on the file, then clicking on "Properties" (Windows) or "Get Info" (Mac OSX).

Conclusion: The majority of STL file opening issues are due to not having the correct Creo Parametric 3D Modeling Software version installed.
