I have a collection of block instances. I am trying to access the geometry within each block. After I query the blocks from their layer and try to explode, approximately 75% of the blocks fail to explode.
The explode error is telling me
“1. Solution exception:Object reference not set to an instance of an object.”
A few details I would not expect to cause an error but in case I’m missing something…
-I have multiple blocks placed in multiple locations
-The blocks are coming from an imported Autocad dwg. import
-Is there some geometry or data type within the blocks that might be causing it to fail? I am seeing no other indication of what is wrong outside of the exception error.
Thanks. I have uploaded the DWG to the link you sent me.
It looks like when I try to assign the blocks that are not exploding in the mass selection will explode when assigned separately so I assume its a bug in the “Explode Object” node and not the blocks themselves. I am wondering if it is failing when there are multiple instances of the same block in different locations? I am trying to confirm that on my end
Please run SystemInfo in the Rhino command line and post the results. I’m not seeing the issue here in the latest build. I’ll send a link if you want to try it.
