Hi,

Yes, with a transaction group but there are counter indications.

  • Layers must exists before you can cast entities on them.
  • An entity or a Block must have an id before you can re-query it.
  • …

Sometimes there is no way around.
For example: Adding a layer requires 2 steps to undo.

  • Undo set current
  • Undo creation

2, 3 … or much more steps to Undo (OO) the last GUI action is not at all strange. :wink:

If it is an option …
It is probably more interesting to complete all actions on the virtual objects before casting them.
The same advice as in this topic

    // Start a new transaction group
    doc.startTransactionGroup();

   // First operation
    var op = new RAddObjectsOperation();
    op.setTransactionGroup(doc.getTransactionGroup());
    ...
    op.addObject(...);
    op.addObject(...);
    di.applyOperation(op);

    // Second operation
    op = new RAddObjectsOperation();
    op.setTransactionGroup(doc.getTransactionGroup());
    ...
    op.addObject(...);
    di.applyOperation(op);

Or automatically within a limited section:

        doc.startTransactionGroup();

        // Add all operations to the current transaction group:
        doc.setAutoTransactionGroup(true);
        ....
        ..
        .
        doc.setAutoTransactionGroup(false);
