1.获取共享参数
1 private string GetSharInfo(Autodesk.Revit.ApplicationServices.Application revitApp)
2 {
3 StringBuilder str = new StringBuilder();
4 DefinitionFile definitionFile = revitApp.OpenSharedParameterFile();
5 DefinitionGroups groups = definitionFile.Groups;
6 foreach (DefinitionGroup group in groups)
7 {
8 foreach (Definition definition in group.Definitions)
9 {
10 string name = definition.Name;
11 ParameterType type = definition.ParameterType;
12 str.AppendLine(string.Format("{0}---{1}", name, type.ToString()));
13 }
14 }
15 return str.ToString();
16 }
2.创建共享参数
1 private void CreateSharInfo(Autodesk.Revit.ApplicationServices.Application revitApp, Autodesk.Revit.DB.Document revitDoc)
2 {
3 try
4 {
5 string sharedParametersFilename = @"C:\shared-parameters.txt";
6 string groupName = "MyGroup";
7 string definitionName = "MyDefinition";
8 ParameterType parameterType = ParameterType.Text;
9 CategorySet categorySet = new CategorySet();
10 Category wallCategory = revitDoc.Settings.Categories.get_Item(BuiltInCategory.OST_Walls);
11 categorySet.Insert(wallCategory);
12 bool instanceParameter = true;
13 BuiltInParameterGroup parameterGroup = BuiltInParameterGroup.PG_DATA;
14 if (!System.IO.File.Exists(sharedParametersFilename))
15 {
16 try
17 {
18 System.IO.StreamWriter sw = System.IO.File.CreateText(sharedParametersFilename);
19 sw.Close();
20 }
21 catch (Exception)
22 {
23 throw new Exception(string.Format("Can't create shared parameter file:{0}", sharedParametersFilename));
24 }
25 }
26 revitApp.SharedParametersFilename = sharedParametersFilename;
27
28 DefinitionFile definitionFile = revitApp.OpenSharedParameterFile();
29 if (definitionFile == null)
30 {
31 throw new Exception("Can not open shared parameter file");
32 }
33
34 DefinitionGroups groups = definitionFile.Groups;
35 DefinitionGroup group = groups.get_Item(groupName);
36 if (group == null)
37 {
38 group = groups.Create(groupName);
39 }
40 Definition definition = group.Definitions.get_Item(definitionName);
41 if (definition == null)
42 {
43 definition = group.Definitions.Create(new ExternalDefinitionCreationOptions(definitionName, parameterType));
44 }
45 ElementBinding binding = null;
46 if (instanceParameter)
47 {
48 binding = revitApp.Create.NewInstanceBinding(categorySet);
49 }
50 else
51 {
52 binding = revitApp.Create.NewTypeBinding(categorySet);
53 }
54 bool insertSuccess = revitDoc.ParameterBindings.Insert(definition, binding, parameterGroup);
55 if (!insertSuccess)
56 {
57 throw new Exception("Failed to bind definition to category");
58 }
59 }
60 catch (Exception ex)
61 {
62 throw ex;
63 }
64 }
3.获取项目参数(API无法创建项目参数的)
1 private string GetProjectParam(Autodesk.Revit.DB.Document revitDoc)
2 {
3 StringBuilder strBuild = new StringBuilder();
4 BindingMap map = revitDoc.ParameterBindings;
5 DefinitionBindingMapIterator dep = map.ForwardIterator();
6 while (dep.MoveNext())
7 {
8 Definition definition = dep.Key;
9 string definitionName = definition.Name;
10 ParameterType parameterType = definition.ParameterType;
11 InstanceBinding instanceBinding = dep.Current as InstanceBinding;
12 if (instanceBinding != null)
13 {
14 CategorySet categorySet = instanceBinding.Categories;
15 strBuild.AppendLine(string.Format("Name:{0} Type:{1} CategorySet:{2}", definitionName, parameterType, categorySet.GetType().ToString()));
16 }
17 else
18 {
19 strBuild.AppendLine(string.Format("Name:{0} Type:{1}", definitionName, parameterType));
20 }
21 }
22 return strBuild.ToString();
23 }
4.创建项目参数
Revit API无法创建项目参数，目前没有找到创建方法。
