Unusable block

Goodmorning everyone,

I’m trying to add some walls to my scene which we’ve defined as blocks. But there are 2 specific blocks that, when imported, become completely unusable.

  • I can’t move them anymore
  • They show up in block manager but can’t select / delete them
  • Pressing delete does nothing

I basically have to exit the file, re-open and the block is gone.

My coworkers don’t have this issue so it’s definitely on my end.

Any advice? Thanks in advance!


Hey Niels -

Just so that I understand, you have separate 3dm files and you are inserting these as blocks in your current document?

That makes it sound like the instance ends up on a locked layer.

I take it you can select the definition in the block manager but you can’t select them in the Rhino viewport?

That’s the Delete button in the block manager?

Please run the Rhino SystemInfo command and copy-paste the result here.

Hey Wim,
Yes, we are using seperate 3dm files as blocks.
They are not on a locked layer, but i also don’t see the draghandle when selecting them.
They do indeed show in the blockmanager, but all options except “refresh” and “delete” are greyed out.
Click delete here or typing delete in command doesnt do anything.

See the log below

Thank you!

Hey Niels -

But you can select them? The color changes and you can see details in the Properties panel?

There is no pop-up when you click the Delete button in the block manager?

The current version is 7 SR32 - I would update to that version first.
Also, you are running 3 third-party plug-ins. Can you reproduce the issue when those are disabled and Rhino restarted?

for now, the problem seems fixed after once importing the block as “grouped”… i can now also import it as a block again without problem.

very strange.
