Adjust blocks size to drawing setup

Hi,
Is it possible to automatically scale blocks in the drawing according to the drawing scale? Say, you inserted blocks in 1"=40' scale. Then you change the scale of the drawing, say to 1"=20' and all the blocks in the drawing get reduced in half. I would greatly appreciate any help you could give me on this one.
Thanks,
Mike

 

You need to detect current objects' scale (via objects themselves or via
stored value) and apply BlockReference.ScaleEntity to uniformly re-scale
them.

I still have a few questions:
- Is that right that AutoCAD won't help me here, and I have to write my own code?
- Is there a way to create an event that triggers every time the drawing scale is changed?
- How can I detect current objects' scale?
