欢迎来到MicroStation Python世界! 使用MicroStation时的常见任务之一是处理选定的元素。本文通过一个Python脚本来演示如何管理MicroStation中的选定元素。
让我们深入探讨在MicroStation中处理选定元素,检查元素是否被选中,迭代它们,并对每个元素执行操作。请参阅Python管理器文章以创建和加载Python项目。将您的项目命名为SelectionSet.py并将其保存到任意文件夹下。在编辑器中打开该项目以编写Python脚本。
导入模块
该脚本首先导入几个模块,这些模块提供了与MicroStation交互以及操作选择集的函数和类。
from MSPyBentley import *
from MSPyBentleyGeom import *
from MSPyECObjects import *
from MSPyDgnPlatform import *
from MSPyDgnView import *
from MSPyMstnPlatform import *
处理选定元素
ProcessSelectedElements()函数旨在管理和处理选定的元素。让我们分步实现这些功能:
def ProcessSelectedElements ():
eh = ElementHandle()
selSetMgr = SelectionSetManager.GetManager()
elmTypeString = WString()
# Check of Selection Set is active
if False == selSetMgr.IsActive():
print("No elements selected...")
# Process selected elements
for i in range(selSetMgr.NumSelected()):
# Get Element Handle of selected element
ret = selSetMgr.GetElement(i, eh)
if BentleyStatus.eSUCCESS == ret:
# Do Something
eh.GetHandler().GetTypeName (elmTypeString, 100)
# Empty Selection Set
selSetMgr.EmptyAll()
main函数初始化当前模型并调用ProcessSelectedElements()函数来处理选定的元素。
下面是完整的脚本:
from MSPyBentley import *
from MSPyBentleyGeom import *
from MSPyECObjects import *
from MSPyDgnPlatform import *
from MSPyDgnView import *
from MSPyMstnPlatform import *
# Get Level Name of Level ID passed as argument
def GetLevelName(lvlId):
global ACTIVEMODEL
levelCache = ACTIVEMODEL.GetDgnFile().GetLevelCache()
it = iter(levelCache)
for level in it:
levelId = level.GetLevelId()
if lvlId == levelId:
return level.GetName()
# Process Selected Elements
def ProcessSelectedElements():
elmTypeString = WString()
eh = ElementHandle()
selSetMgr = SelectionSetManager.GetManager()
# Check of Selection Set is active
if False == selSetMgr.IsActive():
print("No elements selected...")
# Process selected elements
for i in range(selSetMgr.NumSelected()):
# Get Element Handle of selected element
ret = selSetMgr.GetElement(i, eh)
if BentleyStatus.eSUCCESS == ret:
eh.GetHandler().GetTypeName (elmTypeString, 100)
msElement = MSElement()
msElement = eh.GetElement()
levelId = msElement.ehdr.level
levelName = GetLevelName(levelId)
print("***")
print(f"Element Description: {elmTypeString}")
print(f"Element Type: {eh.ElementType}, Element ID: {eh.ElementId}")
print(f"Level Name: {levelName}, Level ID: {levelId}")
# Empty Selection Set
selSetMgr.EmptyAll()
# Main function
def main():
global ACTIVEMODEL
ACTIVEMODEL = ISessionMgr.ActiveDgnModelRef
ProcessSelectedElements()
# Main
if __name__ == "__main__":
print("********** Selection Set **********")
main()
运行/执行项目
从当前模型中选择一些元素,然后从Python管理器对话框中选择项目SelectionSet.py并运行/执行Python脚本。
选定的元素信息(描述、类型、Id、层名称、层Id)将显示在MicroStation文本窗口中。
此脚本提供了一个使用Python处理MicroStation中选定元素的基本框架。您可以自由定制脚本以满足您的特定需求,并将其集成到您的工作流程中。
祝您编程愉快!
