Dynamic block doesnt correctly update after property value change

Anonymous — Tue, 17 Mar 2020 15:18:46 GMT

Hi,

I'm writing a script that needs to update a dynamic block reference size. When I modify the block reference through the DynamicBlockReferencePropertyCollection, it doesn't get visually updated in the same way as it would if I would move the grip.

Code:

private void UpdateBlockReferenceParameter(Database db, BlockReference blockRef, int referenceIndex, double value) { var objectID = blockRef.Id; using (Transaction transaction = db.TransactionManager.StartTransaction()) { DBObject obj = transaction.GetObject(objectID, OpenMode.ForWrite); BlockReference br = ((BlockReference)obj); br.DynamicBlockReferencePropertyCollection[referenceIndex].Value = value; transaction.Commit(); } } ... for (int i=0; i<br.DynamicBlockReferencePropertyCollection.Count; i++) { if (br.DynamicBlockReferencePropertyCollection[i].UnitsType == DynamicBlockReferencePropertyUnitsType.Distance) { UpdateBlockReferenceParameter(database, br, i, (double)(200 + i)); } }

And this is the result:

On the top: the original

In the middle: the dynamic block after running this snippet

On the bottom: the same dynamic block after moving the grip.

The middle version (which is the problem) fixes itself if I move the grip by a small amount after running the script.

What is wrong with what I am doing? How can it be solved?
