What check to ensure an object is pedigree and not a block instance?

Hi,
V5,
Dont wish to bring in trouble, and wish to make sure an object I have found is not a block instance.
What checks do I run to check all is pedigree original and not a block instance etc. All is good to go.

Cheers

Run _SelBlockInstance?

Hi,
V5
says no objects found so thats ok,
I then copy paste this simple nut and bolt I had drawn a few yrs ago into my project and it takes 20secs or so…Mmmmm !
copy paste into a new file and also very slow.
yet file size 369kb

as my project takes over 30secs to save as it has 2 meshes, that on top could be a killer.

Just what is going on ?
here it is
bolt and nut copy paste takes ages.3dm (369.6 KB)

Does it take a long time to copy and paste also in Rhino 8 or even 7? Over here in Rhino 8 it is pretty much instant.

I would insert the nut and bolt file as a linked block. Keeps the file size low even when copied many times…
