Description | The "H/D Ratio" is a measure of the structural slenderness. The property "H/D Ratio" is activated upon selection of the "Shape" property (symbol S in the "Activation Rule" below). The available "Shape" S options are: - "CV" -> Cylindrical Vertical; - "CH" -> Cylindrical Horizontal; - "CVD" -> Cylindrical Dished Vertical; - "CHS" -> Cylindrical Hemispheroidal; - "CHD" -> Cylindrical Dished Horizontal. |
