Insert Dynamics block with parameters and attributs

KZambaux — Mon, 04 Feb 2019 14:53:56 GMT

Hi,

I have a block with parameters and attributs.

I can insert it. I see parameters and I can use it.

However, I don't have the attributs.

Attached, there are the block I want to insert and the code I am using.

What am I missing?

Thanks for your help

Ahmed

The code was not in my previous post:

[CommandMethod("MyCommand3")]
        public void MyCommand3() // This method can have any name
        {
            InsertBlock3(Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument.Database, sourceFileName, new Point3d(0, 0, 0));
        }

        public static void InsertBlock3(Database db, string FileName, Point3d InsertionPoint, double Rotation = 0)
        {
            ObjectId blkid = ObjectId.Null;

The steps of your code doing are correct, but you have code error where you used wrong BlockTableRecord (ModelSpace) to find AttributeDefinition in this line:

                            if (btr.HasAttributeDefinitions)
                            {
                                // Add attributes from the block table record
                                foreach (ObjectId objID in btr)

You are supposed to use "acBlkTblRec" instead of "btr".

Thanks for your help. However, your solution doesn't solved my problem.

I still don't have access to attributs.

Via the command line in Autocad, I used the command ATTSYNC. Then I select my block. Here, attributs are showing up.

How to perform ATTSYNC in code?

Maybe my issue is coming from the attributs themselves? Are they correctly defined?

Hi,

Your idea was right!! Thanks for your help.

I need also to change a little my code.

Here is the code I used:

public static void InsertBlock3(Database db, string FileName, Point3d InsertionPoint, double Rotation = 0)
        {
            ObjectId blkid = ObjectId.Null;
            using (Database bdb = new Database(false, true))
            {
                using (Transaction tr = db.TransactionManager.StartTransaction())
                {
                    bdb.ReadDwgFile(FileName, System.IO.FileShare.Read, true, "");
                    blkid = db.Insert(System.IO.Path.GetFileNameWithoutExtension(FileName), bdb, true);

                    BlockTable bt = (BlockTable)tr.GetObject(db.BlockTableId, OpenMode.ForRead);

                    BlockTableRecord btr = default(BlockTableRecord);
                    btr = (BlockTableRecord)tr.GetObject(bt[BlockTableRecord.ModelSpace], OpenMode.ForWrite);


                    using (btr)
                    {
                        BlockReference bref = new BlockReference(InsertionPoint, blkid);
                        using (bref)
                        {
                            BlockTableRecord acBlkTblRec;
                            acBlkTblRec = tr.GetObject(blkid, OpenMode.ForRead) as BlockTableRecord;

                            BlockTableRecord accurspaceblktblrecord = tr.GetObject(db.CurrentSpaceId, OpenMode.ForWrite) as BlockTableRecord;
                            accurspaceblktblrecord.AppendEntity(bref);
                            tr.AddNewlyCreatedDBObject(bref, true);

                            if (bref.IsDynamicBlock)
                            {
                                DynamicBlockReferencePropertyCollection dynBrefColl = bref.DynamicBlockReferencePropertyCollection;
                                foreach (DynamicBlockReferenceProperty dynBrefProps in dynBrefColl)
                                {
                                    if (dynBrefProps.PropertyName == "Visibility1")
                                    {
                                        dynBrefProps.Value = "M36";
                                    }
                                }
                            }

                            if (acBlkTblRec.HasAttributeDefinitions)
                            {
                                // Add attributes from the block table record
                                foreach (ObjectId objID in acBlkTblRec)
                                {
                                    DBObject dbObj = tr.GetObject(objID, OpenMode.ForRead) as DBObject;

                                    if (dbObj is AttributeDefinition)
                                    {
                                        AttributeDefinition acAtt = dbObj as AttributeDefinition;

                                        if (!acAtt.Constant)
                                        {
                                            using (AttributeReference acAttRef = new AttributeReference())
                                            {
                                                acAttRef.SetAttributeFromBlock(acAtt, bref.BlockTransform);
                                                acAttRef.Position = acAtt.Position.TransformBy(bref.BlockTransform);

                                                acAttRef.TextString = acAtt.TextString;

                                                bref.AttributeCollection.AppendAttribute(acAttRef);

                                                tr.AddNewlyCreatedDBObject(acAttRef, true);
                                            }
                                        }
                                    }
                                }
                            }
                        }
                    }
                    tr.Commit();
                }
            }
        }

With this code, attributs are showing perfectly.

I used this code as well

https://help.autodesk.com/view/OARX/2019/ENU/?guid=GUID-2107599E-9405-4D8B-A6DD-83D603B41568

I am still facing an issue.

As said, attributs are showing up. However, when I move the block, then regen, attributs values are not updated.

When I insert my block via the tool itself, I can move the block, and attributs are updated with a regen. Here nothing is updated.
