Hello Ruben,
This sounds like you didn’t save your configuration settings. To prevent this issue, once you’re finished customizing, click the disc icon to save your drawing set:
This will give you the option to save to the location of your choice (you can keep it with the other ConDoc drawing sets, or save them to your project-specific folders). To reload your drawing set, click on the “Folder” icon in the configurator.
Hope this helps!
