hello guys does anyone knows why when i created a block by select objets node , it work for the first one and for the other one it works also but the first one disappears see video

List.Map and Function.Apply likely avoid the issue in the C3D version as they don’t utilize binding under the hood, but if the data is serialized into the dwg all bets are off.

As a workaround close Dynamo without saving in order to avoid binding

It’s an issue resulting from element bindings. There’s been a lot of discussion about it and I haven’t heard of a good solution yet. Would love to know if anybody has a workaround.
