Copy and paste scale

[Hatam_Nazem]

Hello, 

"R1d16" is a copy of "R1d15"
I have a problem copying and pasting objects (not just blocks, everything) in my drawing "R1d16".
Everything is 12X bigger (which is foot to inch scale factor) when I tried to copy from "R1d15". and it doesn't make sense because they are almost the same file, Both files have the same units.

I thought many I changed the scale in R1d16 so, I use Collaborate to check the size, they were the same size.

I've tried "INSUNITSDEFTARGET", "INSUNITSDEFSOURCE" and "INSUNITS"

Can everyone explain what happens, and what System variable changed in my Autocad?

Thank you very much in advance.

"I've tried "INSUNITSDEFTARGET", "INSUNITSDEFSOURCE" and "INSUNITS""

What setting values did you try for each of these?

This is not the MAP/C3D forums, looking at your two file's content.
Are you actually using one of those, or plain AutoCAD?

May I ask, how are we over here not familiar with your content are to determine what scale is what in your two DWGUNITS-ARE-SET-TO-INCHES files?

I can copy/paste both ways with your files and they now both look identical to me. And if I copy/paste from each into an empty "inches" dwg file they both look exactly the same to me.

I'm using Civil 3D, but I know some system variables changed in my C3D.
I resisted C3D to default setting and it was fixed.
I wanted to know which variable cause that problem.
