C3D-0319 · 260714 Huckaby R2: read the GRCV squiggle linetype definition done

READ-ONLY. Dumps the GRCV linetype (the AutoCAD squiggle power-line pattern already loaded here) dash by dash with its shape number, scale and the shape style/SHX file it needs, plus every shape-file text style in the drawing.

C# payload

// GRCV is the squiggle pattern already in this drawing. Read its definition, and check the
// GRCV.shx shape file it depends on is available - a shape linetype draws nothing if the SHX
// is missing.
Log("drawing: " + Db.Filename);
var ltt = (LinetypeTable)Tx.GetObject(Db.LinetypeTableId, OpenMode.ForRead);
foreach (string nm in new[] { "GRCV", "POWER_LINE" }) {
    if (!ltt.Has(nm)) { Log(nm + ": not loaded"); continue; }
    var r = (LinetypeTableRecord)Tx.GetObject(ltt[nm], OpenMode.ForRead);
    Log(string.Format("{0}: dashes={1} patLen={2:F3} \"{3}\"", r.Name, r.NumDashes, r.PatternLength, r.Comments));
    for (int i = 0; i < r.NumDashes; i++) {
        string txt = ""; ObjectId sid = ObjectId.Null; double sc = 0; 
        try { txt = r.TextAt(i); } catch { }
        try { sid = r.ShapeStyleAt(i); } catch { }
        try { sc = r.ShapeScaleAt(i); } catch { }
        string sname = "";
        if (!sid.IsNull) { try { var ts = (TextStyleTableRecord)Tx.GetObject(sid, OpenMode.ForRead); sname = ts.Name + " file=" + ts.FileName; } catch { } }
        int shp = 0; try { shp = r.ShapeNumberAt(i); } catch { }
        Log(string.Format("   dash{0} len={1,7:F3} shapeNo={2} scale={3:F3} text=\"{4}\" style={5}",
