Pset_Width Specifies the general properties for a Width event. IfcReferent/WIDTHEVENT IfcReferent/WIDTHEVENT Side Specifies if the width is measured to the RIGHT or to the LEFT of the curve referenced by the placement, or if the same value is applied to BOTH sides. LEFT RIGHT BOTH LEFT Left side Left side RIGHT Right side Right side BOTH Both sides TransitionWidth The type of transition of width used between the previous event and this event. CONST LINEAR CONST Specifies that transition of the width between the previous width event and this event shall be constant and equal to the previously specified width meaning that the change in width shall occur instantaneously at the location of this event. LINEAR Specifies that the transition of the width between the previous width event and this event shall be linearly interpolated providing a gradual width change. NominalWidth The nominal overall width of the object. The size information is provided in addition to the shape representation and the geometric parameters used within. In cases of inconsistency between the geometric parameters and the size properties, provided in the attached property set, the geometric parameters take precedence. Nominal Width 公称幅 공칭 폭 呼び幅寸法。 폭 치수
