Copy/Paste with Ctrl-V causing delay with high CPU usage

Anonymous — Fri, 04 Nov 2016 13:39:01 GMT

I'm experiencing an unusual issue when trying to copy objects, even within the same DWG. I have always used Ctrl-C/Ctrl-V for copy paste within CAD except for blocks where I use the Copy command in the shortcut menu. I've never had an issue with this method.

However, now when I try to copy anything (block, text, mtext, line, pline, etc...) I get a 2 second delay before the object appears on the screen and the command can be completed. This is accompanied with a sharp spike in CPU usage (0-5% prior to command, 70-80% during the 2 second delay). This occurs with multiple drawings, both new and old, and of all file sizes.

This does not occur in other programs like Word or Excel, so I don't think the issue lies with Windows or the CPU itself, although I'm not sure how I'd confirm this assumption.

Does anybody have any experience with this?

Thanks!

I am now using Autocad MEchanical 2024 and it has started doing the same thing. A couple weeks ago everything was fine, now pasting even a simple block causes the freezing for a few seconds and CPU usage to jump from 2-3% to 50%. The same thing happens when I use the Move command as well. (I have an I9-10900X) I have used Autocad Daily for years but I just upgraded to 2024 a few months ago.
