Invisible lines Style

[Anonymous]

Im starter in working with revit API and i have a question about the invisible lines style. I want to draw a detail line with this style using API. Is this possible to do that?

Hi,
If you are referring to the style '<invisible lines>' (or something like that), then yes. Just use a filter (filteredelementcollector that looks for a style of that name. I'm unaware of a language independent way of doing that.

Thanks for your reply 

this is my code but it doesn't work

public Result Execute(ExternalCommandData revit, ref string message, ElementSet elements)
{

Document doc = revit.Application.ActiveUIDocument.Document;
Application app = revit.Application.Application;
XYZ st = new XYZ(0, 0, 0);
XYZ end = new XYZ(1000, 1000, 0);
Line geomline = Line.CreateBound(st, end);
View v = doc.ActiveView;
Autodesk.Revit.Creation.Document doc1 = doc.Create;
DetailCurve l1 = doc1.NewDetailCurve(v, geomline);

Categories categories = doc.Settings.Categories;
FilteredElementCollector col = new FilteredElementCollector(doc);
col.OfCategory(BuiltInCategory.OST_InvisibleLines);

l1.LineStyle = (GraphicsStyle)col;

            List<GraphicsStyle> _styles = new FilteredElementCollector(doc)
            .OfClass(typeof(GraphicsStyle))
            .Cast<GraphicsStyle>()
            .ToList();

            GraphicsStyle invisibleLineStyle = null;
            foreach (GraphicsStyle g in _styles)
            {
                if (g.Name == "<Invisible lines>")
                {
                    invisibleLineStyle = g;
                    break;
                }
            }
