Hi ,I am trying to create a face from modellines (which includes both lines and curves) and then using that face as a based for creating a direct shape.are there any option for creating the face?
Thanks so much,

Hi ,

thanks for your respond.my problem is how first I could create face from series of model lines (both curve and line are included in set of model line) and then your solution comes  after that.

also I rather to  filter   all model line based on the graphic style in whole doc than doing selection.

my problem is creation of face from those sets of model line.

Please advise!

Thanks,

Hi @Anonymous ,

From my understanding, it is not possible to create a face directly via API.

First, understand what is face is and how it works in Revit

My suggestion is to create an extrusion element from a set of model lines and from the created element you can get the faces.

Hi @Anonymous ,

To get the face

 //Element created by the model line
                Element e;

                Options option = app.Create.NewGeometryOptions();
                option.ComputeReferences = true;
                option.IncludeNonVisibleObjects = true;
                option.View = doc.ActiveView;

                GeometryElement geoElement = e.get_Geometry(option) as GeometryElement;
                foreach(GeometryObject geoObject in geoElement)
                {
                    Solid solid = geoObject as Solid;

                    //The Face Array contains all the faces and from the face array, you can get your required face
                    FaceArray faceArray = solid.Faces;
                }
