1、Revit在橋梁中的應用二次開發篇（1）族建模篇簡單講了怎么在revit軟件中手動建橋梁模型，更多的基礎操作的 內容可以直接看revit在建筑中應用的相關教程，其實也是相通的，沒必要多 講。這次誠意滿滿，花了兩天時間專門研究二次開發中族的應用。以下代碼親 測可試，結合AUTODESK REV二次開發基礎教程可以獲得更好的效果。因 為書本上都是一些代碼片段，而且是基于2015版的，在2016版的revit上部分代碼跑不了。我也嘗試了很久，終于基本上搞通了族相關的語法。基礎知識直接看書，這里直接上代碼。書里的代碼片段可以想辦法插到完 整代碼中運行。1、找到族實例/用id找到族實例Elemerit

26、到重復的名字，只能用GetParameters 得到一個集合，如果你只用唯一的名字，那只用取 list0 就可以了IList <Parameter > list = familyInstance . GetParameters (" 底高度 "); Parameter param = list 0;strParamInfo += param. Definition .Name + "value is:" + param. AsValueString () + "n" ;/ 方法三：見下圖/ 修改參數的值Transactio
