It came up when I needed to export a schedule containing Walls, Floors, Roof, Beams and Columns.
For consistency I needed to export the Height/Thickness of all the elements ( Because Length and Width are not available currently for Floors and Roof). Problem was in an inconsistency in "naming" of a parameter describing the same property.
Also maybe make the Width and Length available somehow for Floors at least if not for Roofs as well.
Currently the workaround is using Dynamo to create a custom schedule and export it to CSV.
