public void GetStructuralType(FamilyInstance familyInstance)
{string message = "";switch (familyInstance.StructuralType){case StructuralType.Beam: // 结构梁message = "FamilyInstance is a beam.";break;case StructuralType.Brace: // 结构支撑message = "FamilyInstance is a brace.";break;case StructuralType.Column: // 结构柱message = "FamilyInstance is a column.";break;case StructuralType.Footing: // 独立地基message = "FamilyInstance is a footing.";break;default:message = "FamilyInstance is non-structural or unknown framing.";break;}
}
