C3D-0109 · READ-ONLY: the fire hydrant and valve entities and their colours [FH-READ] done

Lists every entity on FIRE_HYDRANT, FIRE_HYDRANT_VALVE and WATER_VALVE with its type, colour override and position, to find why four entities show as three and why they render blue while the layer is red. No changes.

C# payload

// READ-ONLY. The 4 FIRE_HYDRANT entities: what they are, their colour and where they sit.
// User sees only 3 and they render blue despite the layer being red - so at least one carries a
// hardcoded colour override, and one may be coincident with another.
var ms = (BlockTableRecord)Tx.GetObject(SymbolUtilityServices.GetBlockModelSpaceId(Db), OpenMode.ForRead);
var lt = (LayerTable)Tx.GetObject(Db.LayerTableId, OpenMode.ForRead);
Log("drawing: " + Db.Filename);

foreach (string nm in new string[] { "FIRE_HYDRANT", "FIRE_HYDRANT_VALVE", "WATER_VALVE" }) {
    if (!lt.Has(nm)) { Log(nm + ": layer missing"); continue; }
    var l = (LayerTableRecord)Tx.GetObject(lt[nm], OpenMode.ForRead);
    Log("");
    Log("=== " + nm + "  layerColor=" + l.Color + " ===");
    foreach (ObjectId id in ms) {
        Autodesk.AutoCAD.DatabaseServices.DBObject o;
        try { o = Tx.GetObject(id, OpenMode.ForRead); } catch { continue; }
        var ent = o as Autodesk.AutoCAD.DatabaseServices.Entity;
        if (ent == null) continue;
        string lay; try { lay = ent.Layer; } catch { continue; }
        if (lay != nm) continue;

        string where = "";
        var cp = o as CogoPoint;
        if (cp != null) where = String.Format("pt {0} \"{1}\" at {2:F2},{3:F2}", cp.PointNumber, cp.RawDescription, cp.Easting, cp.Northing);
        var br = o as BlockReference;
        if (br != null) where = String.Format("block {0} at {1:F2},{2:F2}", br.Name, br.Position.X, br.Position.Y);

        Log(String.Format("  [{0}] {1,-16} color={2,-10} {3}", o.Handle, o.GetType().Name, ent.Color, where));
