When placing a Column that will intersect a Composite wall, your choice of Geometry method – wrapped or unwrapped – will affect the display of the wall/column in the Floor Plan.
Use the wrapped/unwrapped icons from the Column Info Box or the Column Settings dialog box to determine how the columns will interact with composite walls.
Wrapped Columns can only break through the core skins of composite Walls. The other wall skins wrap around the column, retaining their thickness.
Unwrapped Columns (those using the Freestanding Construction method) do not modify the shape of the wall, just cut out a place for themselves, breaking through all wall skins.
The separator line between wall skins and the column are removed where their Building Materials match.
Wrapped Columns (those placed with the “wrapped” construction method) break through the core skins of composite Walls, provided that the column intersects the core of the composite Wall. The other (non-core) wall skins wrap around the column, thus adding this thickness to the column.
Note: For composites, the skins that are “core” are defined in Options > Element Attributes > Composites.
Note: Wrapping is not available for curved or polygonal Walls, or for Columns whose veneer is defined as “Finish”.
In 3D view, Columns placed with the Wrapped Construction Method will inherit the Surface of the connecting Walls, even if the wall is not a composite wall, and even if there are no wall skins configured to actually wrap around the Columns.
