Revit二次开发 族参数的获取

Posted 2020-12-11 liaocheng

 

本文章代码写的是对族参数的获取，并转成DataTable可作为数据源直接绑定在form窗体控件上

流程思路为：

1.在固定位置找到族文件，加载到项目中

2.读取族文件中所有类型：Get_FamilySymbol(Family family);

3.获取族文件参数： GetParameter(Element e, string header)

4. 获取族文件中所有类型参数：getSymbolpara()

5.将族类型信息参数转成DataTable表格：ShowAllBuildinPara()

6.卸载族文件

　　　　tran.Start("载入族");
　　　　bool b = doc.LoadFamily(s,out family);
　　　　tran.Commit();
　　　　if (b){TaskDialog.Show("11","加载成功");} 
　　　　Get_FamilySymbol(family);//获取族类型
　　　　Element element = family as Element;
　　　　GetParameter(element,"11");//获取族文件参数
　　　　getSymbolpara();//获取族类型参数
　　　　ShowAllBuildinPara();//将族类型信息参数转成table表格
　　　　Transaction trandelete = new Transaction(doc);//创建事物
　　　　trandelete.Start("删除族");//开启事物 
　　　　trandelete.Commit();//关闭事物
　　　　return Result.Succeeded;
