Drafting Elements are strictly two-dimensional: they include Lines, Hotspots, Figures and Drawings. With the exception of Drawings, they do not appear in list views.
The Floor Plan and Section/Elevation/Interior Elevation and 3D Document display of drafting elements depends on the attribute choices made for them in their respective Tool Settings dialog boxes. Attribute sets for Drafting Elements (pencolors, line types, fill types) are managed from the dialog boxes in Options > Element Attributes.
For faster display or output, the 2D appearance of some of the attributes can be modified using the commands at View > On-Screen View Options.
