Topic: Dynamic block & BlockTableRecord.GetBlockReferenceIds method

Hi all.
Fragment of my code:

Code: [Select]

...
//btr - it is BlockTableRecord.
//db - it is Database object.
using (Transaction t = db.TransactionManager.StartTransaction()) {
BlockTable bt = (BlockTable) t.GetObject(db.BlockTableId, OpenMode.ForRead);
foreach (ObjectId brId in btr.GetBlockReferenceIds(directOnly, false)) {
...
Problem code row:

Code: [Select]

btr.GetBlockReferenceIds(directOnly, false)if btr is dynamic block, then it's row can't find block reference ids. Why?

Thank you.

For DynamicBlock here is GetAnonymousBlockIds

You're semi correct.

In fact, GetAnonymousBlockIds returns BlockTableRecords, not BlockReferences.  You'd then need to get the .GetBlockReferenceIds of the Anonymous BlockTableRecords to get the Anonymous BlockReferences.

I know it. The subject isn't actual for a long time, but all the same thanks for the answer.
