Revit二次开发小技巧（十二）组构件修改方法分享

有时候会涉及到组构件的修改，当是又想通过这一次的修改，可以同步到相同的组构件中。这里给大家分享一个自己封装的组构件修改的类，希望可以给大家点帮助。

public class GroupMethod{/// <summary>/// 目标组(名字、相同组名称的集合)/// </summary>private List<Tuple<string, GroupType, IEnumerable<Group>>> TargetGroupList = new List<Tuple<string, GroupType, IEnumerable<Group>>>();/// <summary>/// 原本组里面的ID/// </summary>private List<List<ElementId>> groupIDList = new List<List<ElementId>>();private Document Doc;/// <summary>/// 错误信息/// </summary>public string ErrorMessage = "";public GroupUtils(Document doc){Doc = doc;}/// <summary>/// 添加组合/// </summary>/// <param name="group"></param>public void AddGroup(Group targetGroup){int findGroupIndex = TargetGroupList.FindIndex(x => x.Item1 == targetGroup.Name);if (findGroupIndex == -1 && targetGroup != null){GroupType groupType = targetGroup.GroupType;var groups = groupType.Groups.OfType<Group>().Where(x => x.Id.IntegerValue != targetGroup.Id.IntegerValue);TargetGroupList.Add(Tuple.Create(targetGroup.Name, groupType, groups));//解组Transaction trans = null;if (!Doc.IsModifiable)trans = new Transaction(Doc, "解组");trans?.Start();groupIDList.Add(targetGroup.UngroupMembers().ToList());trans?.Commit();}}/// <summary>/// 修改组里面的构件结束/// </summary>/// <returns></returns>public bool ChangeEnding(){try{Transaction trans = null;if (!Doc.IsModifiable)trans = new Transaction(Doc, "重新成组");trans?.Start();for (int i = 0; i < TargetGroupList.Count; i++){var groupTuple = TargetGroupList[i];Group nwGroup = Doc.Create.NewGroup(groupIDList[i]);Doc.Regenerate();GroupType nwGroupTyple = nwGroup.GroupType;foreach (var oldGroup in groupTuple.Item3){oldGroup.GroupType = nwGroupTyple;}//删除原本的组Doc.Delete(groupTuple.Item2.Id);Doc.Regenerate();nwGroupTyple.Name = groupTuple.Item1;}trans?.Commit();return true;}catch (Exception ex){ErrorMessage += $"{ex.Message} 请联系开发人员tn";return false;}}}
