C3D-0394 · READ-ONLY: SEWER_* E1 layers on the ACAD C-Store [C3D-E1READ2] done

Lists every SEWER* layer with top-level and in-block counts, so the E1 layers can be mapped to their standard SEWER counterparts.

C# payload

// Find SEWER_*_E1 (or "SEWER_XX E1") layers and their standard SEWER_XX counterparts, with
// top-level vs in-block counts, so the E1 objects can be moved to the standard layers.
Log("drawing: " + Db.Filename);
var bt = (BlockTable)Tx.GetObject(Db.BlockTableId, OpenMode.ForRead);
var lt = (LayerTable)Tx.GetObject(Db.LayerTableId, OpenMode.ForRead);

var top=new Dictionary<string,int>(); var blk=new Dictionary<string,int>();
foreach (ObjectId bid in bt){ var def=(BlockTableRecord)Tx.GetObject(bid,OpenMode.ForRead); var d=def.IsLayout?top:blk; foreach (ObjectId sid in def){ var e=Tx.GetObject(sid,OpenMode.ForRead) as Autodesk.AutoCAD.DatabaseServices.Entity; if (e==null) continue; if(!d.ContainsKey(e.Layer)) d[e.Layer]=0; d[e.Layer]++; } }

Log("=== all SEWER* layers ===");
foreach (ObjectId id in lt){
    var l=(LayerTableRecord)Tx.GetObject(id,OpenMode.ForRead);
    if (l.Name.IndexOf("SEWER",StringComparison.OrdinalIgnoreCase)<0) continue;
    int t=top.ContainsKey(l.Name)?top[l.Name]:0, b=blk.ContainsKey(l.Name)?blk[l.Name]:0;
    Log(string.Format("  {0,-34} top={1,-4} inblk={2,-4} {3}{4}", l.Name, t, b, l.IsFrozen?"FRZ ":"", l.IsOff?"OFF":""));
