#RTCEUR Wish 2 – Highlight and Isolate Warning Elements

@marcellosgamb suggested an API that runs thru every error in a model turns element w/error red then as u fix each error turn normal

There is no API access to the Revit “Review Warnings” data, so this implementation requires the user to export the warning data. The program then imports this HTML, parses it to find the element IDs, and then isolates and colors the elements in two 3D views.

public void ShowWarningElements()
{
    Document doc = this.ActiveUIDocument.Document;

    string filename = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments), "warnings.html");

    IList<ElementId> ids = new List<ElementId>();

    using (StreamReader sr = new StreamReader(filename))
    {
        string line = "";
        while ((line = sr.ReadLine()) != null)
        {
            string[] row = System.Text.RegularExpressions.Regex.Split(line,"id ");
            if (row.Length != 3)
            {
                continue;
            }
            string id1 = row[1].Split(' ')[0];
            string id2 = row[2].Split(' ')[0];

            ids.Add(new ElementId(int.Parse(id1)));
            ids.Add(new ElementId(int.Parse(id2)));
        }
    }    

    View isolateView = new FilteredElementCollector(doc).OfClass(typeof(View)).Cast<View>().Where(q => q.Name == "IsolateWarningElements").FirstOrDefault();
    View overrideView = new FilteredElementCollector(doc).OfClass(typeof(View)).Cast<View>().Where(q => q.Name == "OverrideWarningElements").FirstOrDefault();

    OverrideGraphicSettings ogs = new OverrideGraphicSettings();
    Color red = new Color(255, 0, 0);
    ogs.SetProjectionLineColor(red);
    ogs.SetProjectionLineWeight(8);

    Element solidFill = new FilteredElementCollector(doc).OfClass(typeof(FillPatternElement)).Where(q => q.Name.Contains("Solid")).First();

    ogs.SetProjectionFillPatternId(solidFill.Id);
    ogs.SetProjectionFillColor(new Color(0, 255,0));

    using (Transaction t = new Transaction(doc, "Isolate/Override Warnings"))
    {
        t.Start();
        isolateView.IsolateElementsTemporary(ids);

        foreach (ElementId id in ids)
        {
            overrideView.SetElementOverrides(id, ogs);
        }
        t.Commit();
    }
}
