Adding Shared Parameters to Families

[raghulan]

Here is what I am trying to add.

1. user would add list of folders which contains all the family files.

2. Get all the files

3. Add parameter to the families

4. I want the shared parameter to be non editable.

Here is the code.

foreach (string li in GVar.rvtFmlyList)
                {
                    string s = "";
                    Autodesk.Revit.DB.Document doc;
                    try
                    {
                        //string directory = @"C:\ProgramData\Autodesk\RVT 2014\Libraries\Australia\Columns";
                        string Def_file = @"C:\Users\raghulang\Desktop\ADVipSecure.txt";

                        // loop through all files in the directory
                        //check directory exists
                        if (System.IO.Directory.Exists(li))
                        {
                            foreach (string filename in System.IO.Directory.GetFiles(li))
                            {
                                //MessageBox.Show("Directory exists!!" + directory + "||" + filename);
                                s += "Family Name,Family Type,";
                                try
                                {
                                    doc = GVar.app.OpenDocumentFile(filename);

                                    if (!doc.IsFamilyDocument)
                                    {
                                        //MessageBox.Show("Not Family" + directory + "||" + filename);
                                        //return; // skip any files that are not families
                                    }
                                    //MessageBox.Show("Family" + directory + "||" + filename);
                                    Autodesk.Revit.DB.FamilyManager familyManager = doc.FamilyManager;

                                    DefinitionFile defFile = Helper.RevitHelper.SetAndOpenExternalSharedParamFile(GVar.app, Def_file);
                                    DefinitionGroups myGroups = defFile.Groups;
                                    DefinitionGroup myGroup = myGroups.get_Item("ADVipSecure");
                                    Definitions myDefinitions = myGroup.Definitions;
                                    ExternalDefinition eDef = myDefinitions.get_Item("Company Name") as ExternalDefinition;

                                    //Family family = Helper.RevitHelper.FindElementByName(doc, typeof(Family), filename) as Family;
                                    //MessageBox.Show(family.Name);
                                    //Document familyDoc = doc.EditFamily(family);

                                    familyManager.AddParameter(eDef, BuiltInParameterGroup.PG_IDENTITY_DATA, true);

                                    doc.Close(false);
                                }
                                catch (Autodesk.Revit.Exceptions.ArgumentNullException ae)
                                {
                                    MessageBox.Show(ae.ToString());
                                }
                                catch (Autodesk.Revit.Exceptions.FamilyContextException ae)
                                {

                                }
                                catch (Autodesk.Revit.Exceptions.FileAccessException ae)
                                {
                                    MessageBox.Show(ae.ToString());
                                }
                                catch (Autodesk.Revit.Exceptions.FileNotFoundException ae)
                                {

                                }

                            }
                        }
                        else
                        {
                            MessageBox.Show("Directory dont exists!!");
                        }
                    }
                    catch (SystemException ex)
                    {
                        MessageBox.Show(ex.ToString());
                    }
                }
                trans.Commit();
            }

I am getting different erros when trying different things such as follows,

Autodesk.Revit.Exceptions.InvalidOperationException: A sub-transaction can only be active inside an open Transaction.
at Autodesk.Revit.DB.SubTransaction.Start()

I am able to get this working,

Now I just want to know how to add a shared parameter to Family type or Symbol and set its value.

JUST INCASE IF IT HELPS SOMEONE..

 if (doc.IsFamilyDocument)
                                {
                                    //MessageBox.Show("Not Family" + directory + "||" + filename);
                                    //return; // skip any files that are not families

Thank you this did help me, still works in 2017.

...except I have no idea what Helper.RevitHelper is, the below substitutions are in bold.

FamilyManager familyManager = famDoc.FamilyManager;
UIDocument uidoc = ActiveUIDocument;

uidoc.Application.Application.SharedParametersFilename = fileName;
DefinitionFile defFile = uidoc.Application.Application.OpenSharedParameterFile();
DefinitionGroups myGroups = defFile.Groups;
DefinitionGroup myGroup = myGroups.get_Item("_98_PRL_Generic Dimensions");

Definitions myDefinitions = myGroup.Definitions;
ExternalDefinition eDef = myDefinitions.get_Item("PRL_WIDTH") as ExternalDefinition;

using (Transaction y = new Transaction(famDoc, "Put in parameter"))
{
    y.Start();
		familyManager.AddParameter(eDef, BuiltInParameterGroup.PG_IDENTITY_DATA, true);
	y.Commit();
}
