Does it still happen after you load-protect Lynx and restart Rhino? I did not see any weird behavior.

Hi thanks for your response.
Yes i have just tested by disabling Lynx and i have restart rhino. but the bug is againe present :frowning:

I am able to reproduce this here (no Lynx installed) sorta - by selecting certain combinations of objects and not others. But it’s not 100% repeatable, I can move, see the anomaly, undo, then redo and I no longer see it. Also depends on the direction of the move, I can only make it happen (sometimes) with moves that are perpendicular to the horizontal beam axis (in Y for example). This definitely looks like a display problem with blocks.

Then @stevebaer needs to have a look at this.

verry thanks

Hello - I don’t see this yet here… Does ClearAllMeshes and then shading again clear this up?


Hi Pascal, I have test the ClearAllMeshes command and the bug is present. :frowning:

Hi @pascal
Try these steps:

  1. Open the original file, don’t move the view.
  2. Set the display mode to shaded.
  3. Select the two smaller gray “brackets” and the 4 uppermost red “pins” you see (together).
  4. Move the selection in the Y direction with the green Gumball arrow.
  5. You should see the effect.
  6. Undo the move, leave the items selected.
  7. Try moving again in Y. You no longer see the problem.

Thanks Mitch - got it now (at least sometimes)- I think I tried every other combination…
