Paint ModelText's face via revit 2015 API

Anonymous · ‎04-21-2016

I'm trying to paint ModelText's face via the APIs and there are some erros in doc.Paint(modelText.Id, face, elementId). But I ever try to paint the FamilyInstance and Wall's face by using the same way is ok. If revit doesn't open ModelText's Transaction document ? Any guidance would be appreciated.

Thanks,

Nicky

// Paint the E_path's face
public void PaintModelTextFaces(ModelText modelText, ElementId elementId)
{
Document doc = modelText.Document;
Autodesk.Revit.DB.Options opt = new Options();
Autodesk.Revit.DB.GeometryElement geomElem = modelText.get_Geometry(opt);

foreach (GeometryObject geomObj in geomElem)
{
if (geomObj is Solid)
{
Solid f = geomObj as Solid;
foreach (Face face in f.Faces)
{
using (Transaction trans = new Transaction(doc))
{
trans.Start("PaintModelTextFaces");
doc.Paint(modelText.Id, face, elementId);
trans.Commit();
}
}
}
}
}

Can I make new family instances or duplicate the modeltext to place it in a project ?

Maybe i have to use this?

ElementTransformUtils.CopyElement(CachedDoc, pickedObj.ElementId, xyz);

FrankHolidaytoiling · ‎09-21-2017

only u need the users to keep a copy of the model text, still i will do some reclining after that one ...ahhh
