When I try to insert a block with attributes in a side loaded dwg with the following code I get the error wrong database at the line brBlock.AttributeCollection.AppendAttribute(ar); . Can someone point me in the right direction of what I'm doing wrong? I have tried getting the getting the blocktablerecord from the blockreference but with no luck.
Thanks in advance.

Reset to default 0The transaction used to insert the new block reference is not commited.
public static ObjectId InsertBlockReference(Database db, string blockName, Point3d position, Dictionary<string, string> attribValues)
{
var brId = ObjectId.Null;
using (var tr = db.TransactionManager.StartTransaction())
{
// Get the BlockTable
var bt = (BlockTable)tr.GetObject(db.BlockTableId, OpenMode.ForRead);
// Check if the BlockTable contains the block definition
if (bt.Has(blockName))
{
// Get the model space
var modelSpace = (BlockTableRecord)tr.GetObject(bt[BlockTableRecord.ModelSpace], OpenMode.ForWrite);
// Insert a new block reference
var br = new BlockReference(position, bt[blockName]);
brId = modelSpace.AppendEntity(br);
tr.AddNewlyCreatedDBObject(br, true);
// Add attribute references to the block reference
// Get the block definition
var btr = (BlockTableRecord)tr.GetObject(bt[blockName], OpenMode.ForRead);
// Get all attribute definitions in the block definition
var attDefClass = RXObject.GetClass(typeof(AttributeDefinition));
foreach (ObjectId id in btr)
{
if (id.ObjectClass == attDefClass)
{
var attDef = (AttributeDefinition)tr.GetObject(id, OpenMode.ForRead);
// if the attribute definition is not constant, create a new attribute reference
if (!attDef.Constant)
{
var attRef = new AttributeReference();
attRef.SetAttributeFromBlock(attDef, br.BlockTransform);
if (attribValues != null && attribValues.ContainsKey(attDef.Tag))
{
attRef.TextString = attribValues[attDef.Tag];
}
br.AttributeCollection.AppendAttribute(attRef);
tr.AddNewlyCreatedDBObject(attRef, true);
}
}
}
}
tr.Commit();
}
return brId;
}
public static void InsertTbm(Database db)

var attribValues = new Dictionary<string, string>

};
InsertBlockReference(db, "Alstom_TBM_DATA01_S_N", Point3d.Origin, attribValues);
}
Added the line ar.SetDatabaseDefaults(db); problem is now resolved
