Objects grouped inside a block instance during `BlockEdit` do not keep their grouping. Once you click **OK** to close the block editor and re-enter `BlockEdit` on the same instance, the grouped objects are ungrouped.

**Steps to Reproduce:**

1. Double-click a block instance to launch `BlockEdit`.

2. Select two or more objects inside the block and run `Group`.

3. Click **OK** to save and exit `BlockEdit`.

4. Double-click the same block instance to re-open `BlockEdit`.

**Result:** The objects lose their group property and become individual, ungrouped elements.

Is it possible to have group definitions persist within block definitions in the **Rhino 9 Beta** release?

@dimitri_jlantiashvil pls run \_SystemInfo and post back the results. If you could send an example file with it, that would be useful.  
I wasn’t able to reproduce it with these steps:

1. I created 2 cubes
2. Made a block out of them
3. Entered BlockEdit by double-clicking
4. Grouped the two cubes
5. Closed/Saved the block
6. Double Clicked the block

Objects are still grouped

Hi **[Gijs de Zwart](https://discourse.mcneel.com/u/gijs)**, thanks for looking into this.

You likely weren’t able to reproduce it because this issue appears to already be fixed in the Rhino 9 Beta you are testing with. However, the bug is definitely still present and reproducible using those exact steps in the current Rhino 8 release.

Would you still like me to post my `_SystemInfo` and an example file from Rhino 8, or is the fact that it’s fixed in the Beta sufficient?

Hi @dimitri_jlantiashvil,

BlockEdit in the V9 Beta contains many fixes. This is one of them.

These fixes will not be ported to V8, unfortunately. These fixes, taken as a whole, required some significant code refactoring. So it’s not possible to separate this fix from all the other fixes that were made.
