Frequently asked questions

How to fix blank work windows in Simplebim.

If you have accidentally performed some action that caused your work windows to become completely blank and display nothing, please follow these steps to resolve the issue.
If this happens you will need to reset the workspace. Since this is not an option in the software you will need to delete the workspace file from the user settings. The default path to the user settings is: 
  1. C:\Users\<username>\AppData\Local\Datacubist\simplebim\7 (For Naviate Simplebim instead of Datacubist it could say i.e. Symetri.)
In this folder there is a Workspaces sub-folder, which contains the saved workspace settings.
  1. C:\Users\<username>\AppData\Local\Datacubist\simplebim\7\Workspaces
Delete all the files in the workspaces sub-folder and the issue is solved.

Why cannot I open a .cube file in the Simplebim Editor?

Saving a file in the One Click LCA plugin saves the file as a .cube file. This .cube file you can only open in the plugin. Opening a .cube file will open the model using the plugin. The reason why you cannot open a .cube file with the Simplebim Editor is because the plugin adds information to the model that the standard version of Simplebim does not know how to read.

Can I export an IFC file from the Simplebim plugin?

Exporting an IFC file from the One Click LCA plugin is not possible by design. Exporting only works in the full version of Simplebim.

How do I release a Simplebim license?

Releasing the license
The license can be released from the About dialog. If you have a single user license you 'move the license to another computer' to release it. If you have a network license you 'release the license permanently'. Releasing the license will close Simplebim, so please be sure to save any unsaved work before releasing the license.

Uninstalling Simplebim
Simplebim can be uninstalled normally through the Windows Control Panel. Uninstalling does not release your licenses. The best practice is to release your license before uninstalling Simplebim. 

Simplebim licenses are further explained on the Simplebim support pages, please check the guidance for releasing licenses here: Simplebim Licensing
