Regarding the instance reference and instance definition

Hello @dale,
I have one query regarding the instance definition and instance reference.
I want to create block once (name - block 01) in Rhino (like solid cylinder). Now two different blocks (name - block 02 and block 03) should refer the first block (i.e. block 01). Now final block (name - block 04) should have block 02 and block 03 referred in it.
So my question is can single block can be referred to two different blocks in Rhino. Is this possible, if yes could you please tell us how.

Yes, as a nested block.

Hi @psomesh94,

Here is an example of creating nested instances using C++.

cmdSampleCreateNestedBlock.cpp

Let me know if you have any questions.
