Nice print and color scheme, Labern! Hi Arjan, If you just load the 3MF file as a model it would not change your workspace. If you do load it as a workspace it will transfer my settings as well. I agree that it's not as clear as it could be in terms of behavior naming the functionality. However, the settings visibility was turned off for this project when it was saved and is also loaded along with the project. So, this is the intended behavior. In practice, a project is your entire workspace + the models that you had loaded when you saved them. I would argue that changing the settings visibility could have a "[ ] Also load workspace settings (settings visibility)" checkbox so that it allows you to have control over keeping these as you had them before. I'm now adding the 3MF file since there's not too much to the 3MF project itself that you might want to load. And the regular 3MF file actually also knows which extruders and profiles to use for which volume, so that's probably the version you wanted in teh first place?

Some remarks, saving a 3MF file in CURA does NOT create a project file. Only explicitly saving a project from file/save project will create a "project 3MF". Also it's not possible to save a project from the save button (only an 3MF) so the save project is implemented very confusingly. 2th issue, If you load this hairy lion project in cura 2.4 ALL you visibility settings are screwed up (empty) on ALL of your machines. Think the behavior on visibility settings in project files, and in general need a bit off rework :)
