When I use the 3d viewer extension ‘Box Selection’, I find that even though my selection box fully contains some components, the components are not selected and when I refresh the page or log back in, the components that are not selected are not the ones that were previously unselectable, which is my model link model.rvt.
How can I solve this problem?
Looking forward to a reply!
Because BoxSelection is not being used other than as an example, it’s not really battle tested so there might be a bug you’re experiencing. Can you please upload your model.rvt to speckle to we can have a look and see what’s going on?
Cheers
I uploaded two model files, here are the links speckle.xyz speckle.systems
However, like you said, the 3d viewer on speckle’s website doesn’t have access to the ‘BoxSelection’ feature, so I accessed the ‘BoxSelection’ feature in my local 3d viewer and was able to visibly show the problem, here’s the video recording I made video
Thank you for your reply. 
Thank you for uploading the file. I’ve had a look and there is a problem indeed with how the top level BVH provides intersected objects to the client code.
We will put this issue up on our priority list and keep you posted!
Cheers
