I'm trying to create a new plug-in on Revit 2016/2017 with the API.
The idea is to copy a set of element from small revit file to a central one to compile them.

Here is the code I'm using :

```
FilterableValueProvider provider = new ParameterValueProvider(new ElementId(BuiltInParameter.ALL_MODEL_TYPE_NAME));
FilterRule rule = new FilterStringRule(provider, new FilterStringContains(), "BY_GO", false);
ElementParameterFilter epf = new ElementParameterFilter(rule, true);
ICollection<ElementId> npText = new FilteredElementCollector(secDoc, secView.Id).WherePasses(epf).ToElementIds();
using (TransactionGroup tx = new TransactionGroup(mainDoc, "Insert " + Main._roomFile.Typology))
{
    ICollection<ElementId> pastedElements;
    tx.Start();
    using (Transaction tr = new Transaction(mainDoc, "Copy elements"))
    {
        tr.Start();
        pastedElements = ElementTransformUtils.CopyElements(secView, npText, mainView, null, new CopyPasteOptions());
        tr.Commit();
    }
    using (Transaction tr = new Transaction(mainDoc, "Move elements"))
    {
        tr.Start();
        pastedElements = new FilteredElementCollector(mainDoc, pastedElements).WherePasses(epf).ToElementIds();
        XYZ originePoint = new FilteredElementCollector(mainDoc, pastedElements).OfClass(typeof(Floor)).First().get_BoundingBox(null).Min;
        XYZ translation = extremitePoint - originePoint;
        translation = new XYZ(translation.X, translation.Y, 0);
        ElementTransformUtils.MoveElements(mainDoc, pastedElements, translation);
        tr.Commit();
    }

    tx.Assimilate();
}

```

When I use it, everything is good except the dimensions. They are inside the new document (I can get them with there id and RevitLookup) but they are hidden. If I select on of them and add a witness line the dimension is now visible again.
I tried to close and reopen Revit and place the vien on a sheet bt nothing.

Any idea ?

Thank you !
