Block editing takes forever when there are many blocks in the model

Rhino Rhino for Windows
1

Does anyone have an idea why block editing takes a really Long time sometimes?
I assume it has something to do with the number of block instances and definitions you have in the model.

In my case (right now) I am working in a model with maybe 100 block definitions ans quite more instances.
I am trying to edit one of These blocks now and opening it took about 15 minutes which makes each editing really annyoing.

Is there any cure for that? Apart from using less blocks as this stuff is Input from other companies…

Hi Dominik - 15 minutes seems excessive to say the least - are the blocks nested or especially complex?

Hi Pascal,

the blocks are nested but not really deep. Nor are they very complex. One example is attached.
Closing it takes another 15 minutes by the way.

When opening this example everything is very quick. But when opening this block in my original file it takes ages…

Hi Dominik - are the blocks inserted as linked (i.e. BlockEdit opens them in a new instance of Rhino) or embedded, so BlockEdit just works directly in the current file?

Hi Pascal,

all of them are embedded.
I just looked up how many blocks there are in the document.
There are about 9000 definitions. I know thats a lot. But all this comes form external sources (Autocad). So there is no way for me to make that stuff less…

I just wonder what happens internally in Rhino so editing a block takes so long

Hi Dominik - I’ve checked with the developer but unfortunately he’s out of the office for a few days…

Hi Pascal,
no worries. This is not urgent at all. But that might be something to improve for the future.

Hi Dominik - can you possibly upload a model that is big enough to show the problem (SaveSmall, Zip) to www/rhino3d.com/Upload , to my (Pascal) attention?

thanks,

Hi there, I am facing same issue with block editing in Rhino 6 and 7 Windows. It takes ages to get into the block to edit it and it tooks another ages to close the dialog when it is edited. This was never problem in Rhino 5. The block contains only text instance for the drawing purposes ie. revision mark which is on all several pages like “Rev-A” i need to change to “Rev-B”. Nothing complex inside the block and block count is only about 10 instances. Why it takes so long? It is annoing while this is just simple text.

Can you share your block so I can test it on my system?

This is not possible with this file. This is running project with sensitive data, i am not allowed to share it.
And just the block itself doesnt show the behavior when you try to edit it. I think it has somethig to do with the complexity of the file.

When there is not yet any drawing in the model - the scene is almost empty, to edit any block is fast.
But later, when the drawings takes place in the scene, and there is lots of curves of the model, it takes ages to edit any block in place.
