C3D ViewFRAME Object Created from Already Created ViewPORT in Layout Space

[Jacob.IsomHASK]

Hoping that someone from this forum might be able to help me with a relatively "simple," request.  Is there a way to create a ViewFRAME C3D Object from an already created ViewPORT in Layout space.

For instance, I've manually created a ViewPORT in Layout Space, and would like to know the exact bounds of this object without manually interpreting it.

I could always draw a bounding rectangle while in the model space view of the ViewPORT in Layout Space to get these bounds intelligibly was just curious. 

Thanks in advance.

Hi @Jacob.IsomHASK ,

Thank you for posting your question. 
If I understand you correctly, you could use the CHSPACE command while you're in the layout space.

Let me know if I misunderstood your question.
