AutoCAD hangs/freezes when running commands, panning and zooming?

AutoCAD hangs/freezes when running commands, panning and zooming?

First off, this happens with whatever version of AutoCAD I use, I have 2016 and 2018 and the same thing happens in both, so my initial guess is AutoCAD is hammering my video card...

 

Whenever panning, zooming or trying to move an object in AutoCAD, it tends to hang, freezing for several seconds before it starts to cooperate again. We are using blocks with attributes on with different visibility's and the hang happens worse on these blocks... The block in particular there can be hundreds if thousands on one drawing as it is one we use constantly. Changing the block is out the question as it is a company wide standard, is there anything I can do to stop AutoCAD from freezing and hanging? It happens in most drawings, doesn't matter if I am in 2018 or 2016 and happens near enough every time I try to move, pan or zoom with a selection made after so much has been added to a drawing.

 

Drawings are usually between 2-4Mb so isn't much data within the drawing in a sense, but with regards to the block I mentioned, this data in the block is repeated hundreds/thousands of times dependant on the drawing in question.

 

However, it isn't just the block it hangs on, it also happens when trying to dimension between lines, objects etc, doesn't have any effect if I use the button on the ribbon or type the command on the command line, it's always the same outcome with the program hanging. 

 

Have just had my C: drive changed in my PC and have gone from Windows 7 to Windows 10 so everything is fresh but am still having the same problem which is why I'm edged towards it being a hardware issue if anything?

Instead of using wipeout, you can use a solid hatch, color 255,255,255 in pretty much any shape closed polygon with line, arc, or elliptical segments.

Bonus: other than a brief "glitch" in (I think) 2016, 255,255,255 hatch never prints black as wipeouts seem to have a recurring habit of doing, really a bad (and potentially embarrassing) thing when a pdf looks great on-screen, but when someone prints the pdf to paper, wipeouts become black....

solids only work when plotting with overwrite, not merge.

Most places I know can't do overwrite, as keeping track of draworder becomes impossible with many xrefs.

You can't have screened stuff in one xref crossing black stuff in one lower so eventually production people get away from that.

I've been having this same problem in a few drawings.  

 

Seems to work better for me when I unload unnecessary images and freeze those layers and freeze any alignments  not in use.  Still crash if I pan/zoom with a paste/block on the cursor.  also crashing if I pan/zoom in the print command.  But the hanging and freezing has gone away with the alignments froze and the images unloaded. 

 

I'm running a high end system with a 1080 graphics card and a lot of ram.  Not thinking the machine is having trouble processing graphics.

I have some oddly discovered specific cause and solution that might help other folks.

-The hang happens with this specific setup: Windows 10 and HDD as the OS disk drive that could have small free space remaining or very fragmented file system.

-The cause is during the random high disk usage spike when background service is actively running, namely: "Superfetch" and "Windows Event Log"

-Autocad seems nothing to do specifically with the hang.

-Solution: the services can be temporarily stop during autocad session by going thru Windows Services application. proceed with caution.

That is a system issue, and I bet other progs would freak out too if you run low on disk space.

Standard practice on troubleshooting acad issues at crash/lock time would be to open task manager (ctrl-shift-esc, not ctrl-alt-del please), and look at what is running the cpu's and memory. Anything odd with the system has to be dealt with first before deciding acad has some bug. Still interesting though.
