Editing a block within a block is maddening

Which is pretty counter-intuitive, measured by the normal standards of the Rhino user interface. A top-level block opens for editing by double clicking, but everything nested below that has to be accessed by picking from a list? That’s always struck me as ugly.

I tried it and switching through the list was slow also. Double click would be very helpful.


Yes, please consider doble clicking. IMO, it just doesn’t make any sense getting into the first block by double clicking and changing the behaviour for sub blocks, it just seems like you can not edit sub blocks within a blocks. There have been many people asking how to do it because the current workflow is no intuitive at all.


Thanks for the added votes on this one. I’ve included them on the existing feature request here https://mcneel.myjetbrains.com/youtrack/issue/RH-29349


Thanks Brian.

Really glad to see my 3+ year old thread living on. Still would love to see this feature!

+1 on double-click

What does it mean when the nested blocks are unavailable for editing?
I’m attempting to change blocks imported from SKP whose blocks have material attributes assigned to default which I’d like to change to "by Layer’. With blocks imported from Skp some of the nested blocks have the ghostbusters symbol and I can’t edit them. I can explode everything and set the material attributes as I want but it’s more steps, and destructive.

I add my vote +1
Importing step files from other programs with nested blocks representing assembled objects result in a pain to edit them without exploding everything.

+1 vote for double clicking on a block within a block! Any progress?

The list doesn’t always work. It’ll get stuck and wont’ edit anything and I end up having to exit and THEN go back in. Unless someone knows how to always make the list work.

Alternative would be to at least let user select the nested block, then run an EditBlock command. This currently doesn’t work either.

Also finding a lot of trouble with this. +1 Vote for double clicking on a block within a block.

+1 vote for this! Blocks within blocks are important!

I know it’s been going for a while but +1 vote on this please.
Or has Rhino been designed to discourage blocks within blocks?

+1 vote for this one too! Coming from sketchup it is really flustrating, having to scroll trough nested blocks menu all the time.

Yep… added y’all’s comments here -

Editing nested blocks is still strange and not intuitive. I wish to:

  • click the nested block and see my selection within Block Edit window (highlight the name or sth…)
  • click the name in Block Edit window and see the selection in 3D without editing it instantly. What usually happens is that I edit nested block and click “OK” which actually closes the whole block edit, but I somehow expect to close only nested block editing and returning one “level up”
  • have better appearance of nested block being edited; at this moment I am getting really strange overlay of the original block grayed out (locked?) so it’s difficult to work on my modifications:

+1 for this topic, 6 years later! I import a lot of geometry from Revit, and it all comes in as a long list of blocks inside of blocks. If I double click on the nested block, why am I not able to directly edit that block?

6 years…wow. +1 to double click for sub blocks.

Oh. Hello.

Look at that. Another thread on this. How surprising.

But don’t worry. Unlike other companies, McNeel listens!
