Parameter of Revit API – 20: Collect FamilyParameter Information Using FamilyParameter Infoer

We talked about collecting FamilyParameter information before. Now let’s see how FamilyParameter Infoer of RevitAddinWizard can assist us to do fulfill the same task. The FamilyParameter Infoer can be found from either the Revit Addin Coder sub-menu under the Tools or from Revit Addin Coder toolbar.

 

 
When the menu item or button is clicked, the FamilyParameter Infoer window will show up:

 

 
If all default settings are accepted and the OK button is clicked, the following FamilyParameter Infoer code will be created and added into the chosen class:

public class RawFamilyParameterInfo
{
    public  string Name { get; set; }
    public  string ElementID { get; set; }
    public  string GUID { get; set; }
    public  string BuiltinID { get; set; }
    public  BuiltInParameterGroup Group { get; set; }
    public  ParameterType Type { get; set; }
    public  StorageType Storage { get; set; }
    public  string Unit { get; set; }
    public  bool Shared { get; set; }
    public  bool ReadOnly { get; set; }
    public  bool Instance { get; set; }
    public  bool Reporting { get; set; }
    public  bool FormulaDetermined { get; set; }
    public  bool CanAssignFormula { get; set; }
}

public static string RawGetDUTString(FamilyParameter p)
{
    string unitType = string.Empty;
    try { unitType = p.DisplayUnitType.ToString(); }
    catch { }
   
    return unitType;
}

public static List<RawFamilyParameterInfo> RawGetFamilyParametersInfo(Document doc)
{
    List<RawFamilyParameterInfo> paramList =
        (from FamilyParameter p in doc.FamilyManager.Parameters
         select new RawFamilyParameterInfo
         {
            Name = p.Definition.Name,
            ElementID = p.Id.IntegerValue.ToString(),
            GUID = (p.Definition as ExternalDefinition) != null ? (p.Definition as ExternalDefinition).GUID.ToString() : string.Empty,
            BuiltinID = (p.Definition as InternalDefinition) != null ? (p.Definition as InternalDefinition).BuiltInParameter.ToString() : string.Empty,
            Group = p.Definition.ParameterGroup,
            Type = p.Definition.ParameterType,
            Storage = p.StorageType,
            Unit = RawGetDUTString(p),
            Shared = (p.Definition as ExternalDefinition) != null,
            ReadOnly = p.IsReadOnly,
            Instance = p.IsInstance,
            Reporting = p.IsReporting,
            FormulaDetermined = p.IsDeterminedByFormula,
            CanAssignFormula = p.CanAssignFormula,
   
         }).ToList();
    return paramList;
}

public static string RawParametersInfoToCSVString<T>(List<T> infoList, ref string title)
{
    StringBuilder sb = new StringBuilder();
    PropertyInfo[] propInfoArrary = typeof(T).GetProperties();
    foreach (PropertyInfo pi in propInfoArrary)
    {
        title += pi.Name + ",";
    }
    title = title.Remove(title.Length - 1);

    foreach (T info in infoList)
    {
        foreach (PropertyInfo pi in propInfoArrary)
        {
            object obj = info.GetType().InvokeMember(pi.Name, BindingFlags.GetProperty, null, info, null);
            IList list = obj as IList;
            if (list != null)
            {
                string str = string.Empty;
                foreach (object e in list)
                {
                    str += e.ToString() + ";";
                }
                str = str.Remove(str.Length - 1);

                sb.Append(str + ",");
            }
            else
            {
                sb.Append((obj == null ? string.Empty : obj.ToString()) + ",");
            }
        }
        sb.Remove(sb.Length - 1, 1).Append(Environment.NewLine);
    }

    return sb.ToString();
}

In terms of how to use these methods, please refer to previous posts for ideas and code examples.
FamilyParameter Infoer of RevitAddinWizard can create all these in a second.
