2 Hàm InitialBlockFromFile
Hàm InitialBlockFromFile có tác dụng tạo mới 1 BlockReference. Nếu BlockTableRecord chưa có sẵn thì sẽ mở bản vẽ theo đường dẫn để Import.
Ngoài ra, còn khởi tạo sẵn các AttributeReference và lưu thành List để sử dụng theo yêu cầu sau này.
Code:
public static BlockReference InitialBlockFromFile(string blockName, string filepath, Point3d p, double angle = 0, double scale = 1)
{
List<AttributeReference> atrs = new List<AttributeReference>();
return InitialBlockFromFile(blockName, ref atrs, filepath, p, angle, scale);
}
public static BlockReference InitialBlockFromFile(string blockName, ref List<AttributeReference> atrs, string filepath, Point3d p, double angle = 0, double scale = 1)
{
Database db = HostApplicationServices.WorkingDatabase;
BlockReference br = null;
using (Transaction mytr = db.TransactionManager.StartTransaction())
{
BlockTable bt = db.BlockTableId.GetObject(OpenMode.ForRead) as BlockTable;
ObjectId blkid = ObjectId.Null;
if (bt.Has(blockName) && !bt[blockName].IsErased)
blkid = bt[blockName];
else
{
if (!File.Exists(filepath)) return br;
Database sourceDb = new Database(false, true);
sourceDb.ReadDwgFile(filepath, System.IO.FileShare.Read, true, "");
using (Transaction tr = sourceDb.TransactionManager.StartTransaction())
{
BlockTable bt1 = tr.GetObject(sourceDb.BlockTableId, OpenMode.ForRead) as BlockTable;
ObjectIdCollection blockIds = new ObjectIdCollection();
if (bt1.Has(blockName))
{
blkid = bt1[blockName];
blockIds.Add(blkid);
IdMapping mapping = new IdMapping();
sourceDb.WblockCloneObjects(blockIds, db.BlockTableId, mapping, DuplicateRecordCloning.Replace, false);
blkid = mapping[blkid].Value;
}
}
sourceDb.CloseInput(true);
sourceDb.Dispose();
}
if (blkid != ObjectId.Null)
{
br = new BlockReference(p, blkid);
br.ScaleFactors = new Scale3d(scale);
br.Rotation = angle;
BlockTableRecord blockDef = blkid.GetObject(OpenMode.ForRead) as BlockTableRecord;
if (blockDef != null)
{
foreach (ObjectId id in blockDef)
{
DBObject obj = id.GetObject(OpenMode.ForRead);
AttributeDefinition attDef = obj as AttributeDefinition;
if (attDef != null && !attDef.Constant)
{
AttributeReference attRef = new AttributeReference();
attRef.SetAttributeFromBlock(attDef, br.BlockTransform);
atrs.Add(attRef);
}
}
}
}
mytr.Commit();
}
return br;
}Load toàn bộ AttributeReference
3 Hàm Initial (Khởi tạo AttributeReference)
Trong dotNet, khi tạo 1 BlockReference mới, sẽ không có sẵn các Attribute. Do dó cần phải khởi tạo bằng hàm Initial sau đây .
Code:
public static List<AttributeReference> Initial(this BlockReference br, Database db = null)
{
if (db == null) db = br.Database;
if (db == null) db = HostApplicationServices.WorkingDatabase;
List<AttributeReference> atrs = new List<AttributeReference>();
ObjectId blkid = db.Search(br.RealName(), TBType.Block);
if (blkid == ObjectId.Null) return atrs;
using (var tr = blkid.Database.TransactionManager.StartTransaction())
{
BlockTableRecord blockDef = tr.GetObject(blkid, OpenMode.ForRead) as BlockTableRecord;
if (blockDef != null)
{
foreach (ObjectId id in blockDef)
{
DBObject obj = id.GetObject(OpenMode.ForRead);
AttributeDefinition attDef = obj as AttributeDefinition;
if (attDef != null && !attDef.Constant)
{
AttributeReference atr = new AttributeReference();
atr.SetAttributeFromBlock(attDef, br.BlockTransform);
atr.TextString = attDef.TextString;
atrs.Add(atr);
}
}
}
tr.Commit();
}
return atrs;
}Cách sử dụng:
Code:
public static ObjectId InsertAtPoint(this Point3d p)
{
ObjectId id = ObjectId.Null;
var db = HostApplicationServices.WorkingDatabase;
var blkname = "YourBlockName";
var att = "Z";
double scale = 1.0;
using (var tr = db.TransactionManager.StartTransaction())
{
var bt = tr.GetObject(db.CurrentSpaceId, OpenMode.ForWrite) as BlockTableRecord;
var br = Tbls.InitialBlockFromFile(blkname, "YourFilePath", p, 0, scale);
id = bt.AppendEntity(br);
tr.AddNewlyCreatedDBObject(br, true);
var atrs = br.Initial();
foreach (var atr in atrs)
{
if (atr.Tag == att)
atr.TextString = p.Z.ToString("0.00");
br.AttributeCollection.AppendAttribute(atr);
tr.AddNewlyCreatedDBObject(atr, true);
}
tr.Commit();
}
return id;
