Qto_PileBaseQuantities Base quantities that are common to the definition of all occurrences of piles. IfcPile IfcPile Length Total length of the pile not taking into account any cut-out's or other processing features. Q_LENGTH Length CrossSectionArea Total area of the cross section (or profile) of the pile. Q_AREA Cross Section Area OuterSurfaceArea Total area of the extruded surfaces of the pile (not taking into account the end cap areas), normally generated as perimeter * length. Q_AREA Outer Surface Area GrossSurfaceArea Total area of the pile, normally generated as perimeter * length + 2 * cross section area. It is the sum of OuterSurfaceArea + (2 x CrossSectionArea) and shall only be given, if the OuterSurfaceArea and CrossSectionArea cannot be established separately. Q_AREA Gross Surface Area GrossVolume Total gross volume of the pile, not taking into account possible processing features (cut-out's, etc.) or openings and recesses. Q_VOLUME Gross Volume NetVolume Total net volume of the pile, taking into account possible processing features (cut-out's, etc.) or openings and recesses. Q_VOLUME Net Volume GrossWeight Total gross weight of the pile without add-on parts, not taking into account possible processing features (cut-out's, etc.) or openings and recesses. Q_WEIGHT Gross Weight NetWeight Total net weight of the pile without add-on parts, taking into account possible processing features (cut-out's, etc.) or openings and recesses. Q_WEIGHT Net Weight
