BIM模型中有很多不规则的构件,在IFC中这些不规则的构件一般用顶点的形式表示,顶点坐标提取路径:
IfcObject->IfcProductDefinitionShape->IfcShapeRepresentation->Item属性->IfcExtrudedAreaSolid
->IfcArbitraryClosedProfileDef->IfcPolyline->IfcCartesianPoint
->IfcArbitraryClosedProfileDef->IfcPolyline->IfcCartesianPoint
revit中创建不规则形状并导出ifc文件

常用的表面是矩形形状的构件属于规则构件,只有一个顶点坐标和长宽值(XDim,YDim),订单制需要自己推算
