Hi,
I am working with blocks in GH with the new native Rhino components and I noticed that if user inputs both breps and blocks, the “Explode Object” component explodes both?
You need to filter by type first. Or group by type…
I always wanted to do this also, but I found the filter components to no be quite intuitive.
How can I group or filter by geometry type?
Elefront makes it very straightforward.
Sorry I’m not at my computer and I don’t remember the details by heart. But right clicking the inputs is where you start…
i have similar issues of exploding a block in Grasshopper. It is showing error “Data conversion failed from Block Instance to Block” for Explode Block Component; and “Solution exception:Object reference not set to an instance of an object.” for Explode Blocks component. I want to create a bounding box around the block. How to do that?
Hey Guys, I havnt received reply to the previous comment so following up on the same. Sharing the file too. I want to explode the block so i can find the outer most point of the block where i need to place another block item. I am also finding that insert block component is not able to find the block from rhino file. The type case is same but still not able to find it. Please help. I was waiting for several days. need to get some progress. Cannot do another without getting this sorted.. Please Help

Two things.
thanks Martin, your suggested workflow works.
I use @martinsiegrist dropdown component to input into the ObjectType Filter:
object-type_value-list.gh (2.2 KB)
Thank you Scott. That helps. Is it part of new updates?
Also wanted to ask what to do when Insert component is showing error “Block ‘TRACK SECTION’ could not be found.” This block exists in the Rhino model but still it is showing this error. how to fix this issue?
Model Block Instance worked in place of Insert Block. Issue resolved ya. Thanks 
How does value list dropdown component work? It seems like on some components it fills values automatically, but when i try it with Equality filter it does not seem to change at all
Depending on the situation you could use the value picker component. The value list component does not auto fill. There’s an option to use a script to populate the value list but I’m not sure if that makes sense since we have the value picker component.
yes but is there even such a component as value picker? and it looks exactly the same, i am confused
Value picker has been added in Rhino 9 WIP.
