Hi,

You can use or get inspiration from these extension methods.

Thanks for you valuable time @_gile @ActivistInvestor

But seems like
Here it is copy pasting the objects from external drawing to the current drawing. Hence the objects that are pasted to the current drawing are not adjusting the scale by itself.
When I am manually trying to import these blocks from "Design Centre" in the "View" tab of the ribbon then they are properly getting scaled
So I am struggling to write the code for the above requirement
