Copy paste between drawings, wrong paste, from previous copy

[Anonymous]

I have seen similar topics, but not this exact one. I will try to explain as simple as possible

I have 3 drawings, 1, 2, 3, 

I want to copy data from drawings 1 & 3, into drawing 2.

When I copy and paste from drawing 1 into drawing 2 - no problem

When I copy and paste from drawing 3 into drawing 2 - problem, what is pasted is what I copied from drawing 1, not 3.

When I try to copy paste drawing 3 into drawing 3 no problem, when I copy paste drawing 3 into drawing 1, sometimes a problem, not always.

It is as that what I copied into the computer/program buffer gets stuck and does delete by itself.

I have tried to restart - no effect

I have tried to save as different file names - no effect

I have tried to -exporttoautocad - no effect

I have tried an array of copy paste mixups - no effect

This is a very frustrating problem. This happens to me quite frequently as I have to work with different drawings from different sources from different versions of dwg and dxf.

Any ideas?

There is no fix for "sometimes": is there something unique about Drawing3? Come from a different source? Is it a DXF and you are trying to paste into a DWG (or the reverse)? Have you tried fixing Drawing3 like this https://knowledge.autodesk.com/support/autocad/troubleshooting/caas/sfdcarticles/sfdcarticles/AutoCA...
Have you tried using WBLOCK commnd to export that copy/paste content into a separate DWG then opening to see if anything is missing?

Your Windows log-in's TEMP folder needs to be emptied while you are at it like this https://www.lifewire.com/how-to-delete-temporary-files-in-windows-2624709

Note: AutoCAD works all the time and best if all of the files are DWG and DXF files of the same year versions to the session of AutoCAD you are using.

Any chance the objects you are refering too are blocks? Otherwise can you explain exactly your method of doing copy paste and the types of objects you are using.

As I mentioned before, I have to use drawings from a variety of sources and this cannot be avoided.

Sometimes is the best I can explain because I haven't noticed a pattern yet to the problem.

I am not sure if they were blocks or not, but I exploded the object in question and was successfully able to copy and paste it this time, thanks for this idea.

This however does not explain why Autocad decides to save a particuler copy into its memory and then pastes it even if other items are copied after. To me it should automatically delete the particular copy in memory and replace it with the new copy.

If exploding the block solved the problem, it means your destination file has a similar named block with different content in it. AutoCAD does not (and never has) replace destination content with source content with copy/paste, you are required to make an extra effort to address the block variation.

Pendeans answer addresses the issue I was trying to get from you. It is windows and not Autocad that is responsible for copy paste to the clipboard if you use Ctrl+c and Ctrl+v. But if the objects are blocks then that is a different matter, as drawings that have blocks with the same names but different content will behave in the way you are describing.

Copy to clipboard can fail if you are copying from a file created in a newer version of AutoCAD. Newer objects and features that have not been exported correctly will not be recognized in older versions.
