Floorplan(2 floors)
The Project Management feature (Project Browser and Project Navigator) was set up with the expectation that you would have separate Construct files for each level for items specific to that floor. You can have spanning Constructs that have objects that extend beyond a single level, such as exterior Walls (especially if they are Curtain Walls) or Stairs. On larger projects, you can have Divisions that separate a level into multiple Construct files as well, if that makes sense for your workflow.
The Constructs are then brought into View files, as needed, as external references to create the model contents for a View that is put on a Sheet, and the annotation is added there.
Model views are then created from the View files, and placed on Sheet files.
The above is an oversimplification but describes the main workflow. If your design has modeled elements that repeat in a building, you can create them in an Element file, and then that file is externally referenced into one or more Construct files for each instance of the repeated elements. You can have working View files if that helps you understand the design better, as well as View files that have multiple Constructs referenced to create a source for a Schedule Table that includes all of the scheduled elements in the project. Multi-level Views are also used for building elevations and sections.
All of the external referencing is managed through the Project Navigator.
If all of that is overkill for you, you can manually break up your model into floors per level, and then manually combine them when you need multiple levels for a particular view on a sheet.
Another alternative is to model everything in one file, and then use a combination of level-specific Display Configurations and level-specific layering to get a viewport to show what you want to see on each level's plan view. @ntellery has blogged extensively about such a system that he set up for his primarily residential/small-scale commercial practice.
Yes, it is different from the workflow in Revit.
To edit the values shown on the Project tab of the Project Navigator, select the icon that looks like a funnel with a pencil in the header of each section to open a worksheet where the properties can be modified.
No. Real-world elements are modeled/drawn in real-world sizes. Changing the annotation scale will not affect them. Changing the annotation scale will affect annotative annotations. Depending on your settings, some annotations may disappear (if they no longer have the current annotation scale assigned, you have disabled automatically adding a new annotation scale to existing annotations, and you are not displaying all annotations regardless of the annotation scale). It will also affect the size of the annotation that has the current annotation scale assigned so that it plots at the correct size for the chosen annotation scale.
