A SIM file contains a 3D scene created by SimLab Composer, a 3D modeling, animation, and rendering application. It stores one or more objects and the surrounding 3D environment. SIM files may also include animations, materials, lighting effects, and annotations.
More Information
SimLab Composer comes with various capabilities, including support for different types of models, 3D rendering, building VR scenes, and creating interactive VR training sessions. When saving a scene with SimLab Composer, the application creates a SIM file, which is the native SimLab Composer scene format.
To create a SIM file with SimLab Composer, select , modify the scene, then select or . After saving the file, you can close it, re-open it, then continue editing the scene in the file.
You can also export SimLab SIM scenes to other formats, such as .STL, .3DS, .DWF, .DWG, .OBJ, .DXF, .DAE, .3MF, .U3D, .USDZ, and .PDF. To export a SIM file with SimLab Composer, select .
How to open a SIM file

A SIM file contains a circuit simulation created by LogikSim, an open-source program used to test and design logic circuits. It stores a circuit design, which includes wire connection points and various components.
More Information
SIM files are created and opened using LogikSim. The files are used to store all types of circuits, such as simple AND gates or complex computing systems. There is no other program that supports LogikSim SIM file type. But LogikSim is available to download for free.
NOTE: LogikSim is typically used by high school and college students to learn about circuits and how they work.

A SIM file may also be a simulation or video game created by Stagecast Creator, a discontinued visual programming app. It contains all the scripts and assets, such as images or sounds, needed to run the simulation or game. Those who want to edit the simulation or game a SIM file contains must open it with Stagecast Creator. Those who just want to run the simulation or game a SIM file contains can open it with Stagecast Player.
More Information
Stagecast Creator was a multiplatform app used primarily to teach children how to program. In Creator, novice programmers could create animated stories, games, and simulations. These programs were saved as SIM files.
SIM files are re-named .ZIP files, which store all the constituent files necessary to run a program. Those constituent files may be compiled scripts, image assets, audio assets, or other program resources. Notably, the files a SIM file contains do not use file extensions, and most of them are named either iMP### or MP###. Thus, determining exactly which file contains what asset can be difficult and time-consuming.
How to open a SIM file
You can open a SIM file with Stagecast Creator or Stagecast Player. Opening a SIM file with Stagecast Creator allows you to both play and edit the simulation or game the file contains. Opening a SIM file with Stagecast Players allows you only to play the simulation or game the file contains.
To open a SIM file with Stagecast Creator, start the program and select . Then, navigate to and open your SIM file.
If you want to extract the assets a SIM file contains, you can do so by renaming it to use the .zip extension (instead of .sim) and then opening it as you would any ZIP file.
