Place Repeating Detail Again

Anonymous — Wed, 22 Feb 2012 16:06:55 GMT

Working on my first batch of programming with the API. Hit my first question that I cannot answer with Google.

I am trying to place a repeating detail. I read this

http://forums.autodesk.com/t5/Autodesk-Revit-API/Place-repeating-detail-using-the-API/td-p/3313195

And it mostly made sense. The problem is, in the code sample it says "// fine (sic) the family symbol here" as a comment in the code. I cannot figure out how to pick the family symbol I want.

I've spent a lot of time with FamilySymbol, but no luck.

Any guidance on selecting the symbol I want to use? And feel free to speak slowly. Like I said, this is my first dive in the Revit API. Thanks.

I'm not 100% if this is what you are looking for but here it is. A sample code searching a family symbol based on category and name. Code is C++/CLI but its somewhat similar with the C#

List<FamilySymbol^>^ familySymbols(Document^ document, 
                                                           BuiltInCategory category,
                                                           String^ name)
{
  // Filters
  ElementCategoryFilter ^categoryFilter = gcnew ElementCategoryFilter(category);
  ElementClassFilter ^classFilter             = gcnew ElementClassFilter(FamilySymbol::typeid);
  LogicalAndFilter ^lFilter                        = gcnew LogicalAndFilter(categoryFilter, classFilter);

  // Elements lookup
  FilteredElementCollector ^elementCollector = gcnew FilteredElementCollector(document);
  elementCollector->WherePasses(lFilter);

  // Find correct element and cast it to FamilySymbol
  List<FamilySymbol^> ^familyList = gcnew List<FamilySymbol^>;
  for each (Element ^elem in elementCollector)
  {
    FamilySymbol ^familySymbol = safe_cast<FamilySymbol^>(elem);
    if(familySymbol->Family->Name->Equals(name)
    {
      familyList->Add(familySymbol);
    }
  }

  return familyList;
}

Thanks. After some c# massagin, it does precisely what I wanted it to do.

Of course, after much pacing, I think I am realizing that I am not knowledgeable enough to know what I really need this to do.

Maybe I should back up and ask everyone, is it even possible to place a Repeating Detail with the API? With the above poster's help, I have been able to place single detail component and a line-based detail component, but no Repeating Detail. I have used different BuiltInCategories, different overloads of the NewFamilyInstance, but no dice.

So, is placing a Repeating Detail even possible?

@Anonymous It looks like you're right - placing Repeating Detail idea is here: Expose Repeated Detail Component to API
