How change the color a element?

Anonymous — Mon, 25 May 2015 22:41:31 GMT

Hello everyone:

I am trying change the color a element but the following code not work. I am using Revit 2015. The element is "Parts".

For to change to color I am using a foreach:

FilteredElementCollector collector = new 

FilteredElementCollector(m_revit.ActiveUIDocument.Document).OfClass(typeof(FamilyInstance));


foreach (FamilyInstance fi in collector)
                    {
Color color = m_revit.ActiveUIDocument.Application.Application.Create.NewColor();
                                      color.Blue = ( byte ) 150;
                                      color.Red = ( byte ) 200;
                                      color.Green = ( byte ) 200;

doc.ActiveView.set_ProjColorOverrideByElement(fi.Id, color);

}

set_ProjColoOverrideByElement is deprecate in Revit 2015?

Thank's for you help.

Regards,

David

Here goes:

UIApplication uiapp = commandData.Application;
UIDocument uidoc = uiapp.ActiveUIDocument;
Application app = uiapp.Application;
Document doc = uidoc.Document;

Color color = app.Create.NewColor();
color.Blue = (byte)150;
color.Red = (byte)0;
color.Green = (byte)0;

Selection sel = uidoc.Selection;

Reference ref1 = sel.PickObject(
ObjectType.Element,
"Pick element to change its colour");

Element elem = doc.GetElement(ref1.ElementId);

List<ElementId> ids = new List<ElementId>(1);
ids.Add(elem.Id);

Transaction trans = new Transaction(doc);
trans.Start("ChangeColor");

doc.ActiveView.set_ProjColorOverrideByElement(ids, color);

trans.Commit();

Thanks & Regards

On 2015 this method was replaced with

uiDoc.ActiveView.SetElementOverrides(....)

Hello,

I am using this code and not works with the parameters element Id and color. I'm doing wrong?.

if (category == "Parts")
{
 FilteredElementCollector collector = new FilteredElementCollector(m_revit.ActiveUIDocument.Document).OfClass(typeof(FamilyInstance));

 int i = 0;foreach (FamilyInstance fi in collector) {
                        
//Get parameters 
//Perforacion y cableado                            
Parameter perforacion = fi.LookupParameter("Dia Planeado de Perforacion e Inyeccion");
//Perfilado                            
Parameter perfilado = fi.LookupParameter("Dia Planeado de Perfilado");
//Acero
Parameter acero = fi.LookupParameter("Dia Planeado de Colocacion de Acero");
//Encofrado                            
Parameter encofrado = fi.LookupParameter("Dia Planeado de Encofrado");
//Concreto                            
Parameter concreto = fi.LookupParameter("Dia Planeado de Concreto");
//Tensado                            
Parameter tensado = fi.LookupParameter("Dia Planeado de Tensado");

if (ParameterToString(perforacion).Equals(day))
{
//change to color: Celeste
Color color = m_revit.ActiveUIDocument.Application.Application.Create.NewColor();
color.Blue = ( byte ) 150;
color.Red = ( byte ) 200;
color.Green = ( byte ) 200;

m_revit.ActiveUIDocument.Document.ActiveView.SetElementOverrides(fi.Id, color);
                            }
}

I believe you need to:

OverrideGraphicSettings ogs= new OverrideGraphicSettings();
ogs.SetProjectionLineColor(color); // or other here

And then

m_revit.ActiveUIDocument.Document.ActiveView.SetElementOverrides(fi.Id, ogs);

Hello Augusto:

Thank's very much for respond.

The code not have errores but the execute in Revit displays the following message:

I not understand the problem in this point.

The Code:

foreach (Part fi in collector){ ...........

if (ParameterToString(perforacion) == day)
 {
TaskDialog.Show("GYM-BIM", "Color Celeste = " + day);
//change to color: light blue
Color color = m_revit.ActiveUIDocument.Application.Application.Create.NewColor();
color.Blue = (byte)255;
color.Red = (byte)0;
color.Green = (byte)255;

OverrideGraphicSettings ogs = new OverrideGraphicSettings();
ogs.SetProjectionLineColor(color); // or other here

m_revit.ActiveUIDocument.Document.ActiveView.SetElementOverrides(fi.Id, ogs);

                            }

David

Please try create the color with:

Color color = new Color(0, 255, 255); // RGB
