Basic workarounds in case of errors while importing projects and other operations with projects

If an exception occurs while importing a project or another error occurs while working with the project and this error is not otherwise specified, perform the following workarounds:

1. Clean the project.

2. If the error still occurs, delete the project-internal database and have it created anew:

   1. Start the explorer of the operating system and go to the folder of the workspace.
      If you are unsure what the folder of the workspace is, select in logi.CAD 3: menu File, command Switch Workspace and Other... – The opened dialog displays the folder of the workspace.

   2. Move on into this sub-folder: .metadata\.plugins\com.logicals.projectindex\database\project-name\

   3. In this sub-folder, delete these files: project.mv.db and project.trace.db

   4. In the project explorer of logi.CAD 3: Delete the project. Make sure that Delete project contents on disk (cannot be done) is cleared in the dialog.

   5. In the project explorer again: Import the project. Now the project-internal database is created anew.
