When working with multiple levels, you may have come across times when the objects in your drawing are visible in the 2D view only by a dashed outline, like this:
Don’t worry - your drawing isn't broken! It is just a way of seeing which level objects belong to, and to maintain visibility of all or some levels when working.
When using multi-levels, only the active level will show components filled in. All other levels that are still visible will just show the outlines of their objects. In the example above, the active level is the Base, which does not contain any objects. Changing the active level to Level 1, however, will show the objects that are placed there:
To change active level, simply right-click the desired Level name at the bottom of the screen, or select it in the Level overview in the Architectural component tab.
