Description
Units data was imported from polygon data in the UNITS column of the Layer to Feature Class sheet. The Door Close Buffer parameter requires polyline data from the UNIT_LINES column. Any values in the OPENINGS and CLOSE_DOORS columns were ignored.
Solution
To use the Door Close Buffer parameter, list one or more CAD polyline layers in the UNIT_LINES column of the Layer to Feature Class sheet. Remove CAD layers from the UNITS column.
