标签：star dialog levels efi extern with amp tran lin 由于Revit的版本问题，在网上找的生成墙图元的代码，在我机器上的Revit 2016中编译不能通过，通过多次调试，终于找到在revit 2016中使用API生成墙图元的代码，现在贴出来。 下面的代码在Revit 2016 + VS2013的环境下通过。 revit API 生成墙图元 标签：star dialog levels efi extern with amp tran lin 原文地址：http://www.cnblogs.com/laoxia/p/7750488.htmlclass CreateWall : IExternalCommand
