Copy/Paste from dxf to template multiple causes original to always paste

[Anonymous]

At work I download a dxf file and copy the auto-created drawing from that file into our built out template in order to finish a project. There are times when I won't see issues with the drawing into getting it into Autocad, and fixing it elsewhere and then re-downloading a new dxf and copying it again is the quickest solution. Often though, when I paste the new drawing into the master template, though I've copied the new drawing, what gets pasted is the first drawing that I copied, not the new drawing.

Put another way, I copy and paste Drawing A from dxf to master template and find issues with Drawing A. I go back to the source, push a few buttons to make the quick fixes and get a new dxf. Copy (ctrl+c) on Drawing B, go to the master template and when I hit ctrl+v, what pastes is still Drawing A. I can go through the same steps and get a Drawing version C and D, but always what gets pasted is Drawing A. I've tried closing AutoCAD completely between copy and paste cycles. And I've tried wiping the computer's clipboard, neither of those works. 

The drawing in the dxf file does start all grouped, if I explode it enough, at some point it will work, but sometimes that will cause other issues. I am using AutoCAD 2018LT, but this is something I've experienced across multiple versions of AutoCAD.

That sounds like your problem right there. If you copy a block from drawing A to drawing B, then copying a changed block (same name) from drawing A to drawing B will NOT update the block in drawing B. You have to remove and purge the block from drawing B in order to bring an updated version.

To clarify terminology, it's not a block specifically, it s drawing (just want to make sure we're on the same page). Whenever I copy and paste i'm copying from a completely different dxf file and  pasting into a blank the blank master template. After copying from drawing A and pasting into the template and seeing mistakes, I have closed AutoCAD completely, then reopened the blank template with drawing version B, but when I go to paste, it is still drawing A that pastes.

I don't suppose you can upload a sample DXF you are having trouble with here?

No, that wouldn't be an option.
