Jerky Cursor in AutoCAD 2018

[Anonymous]

I've just started AutoCAD 2018 version.

I have everything working fine EXCEPT for a jerky cursor.

It works smoothly until a command is started.

Then, it takes a full second before it moves and then it jerks, almost as if a snap was set.

I've check past postings and have adjusted as suggested, but, to no avail.

I'm ready to start over and follow any suggestions you all out there might have.

@Anonymous,

Hello,
The full command is DDPTYPE (that's why the "ype"); after the box opens, just do "OK" (=valid): I my case it solves the jerky cursor problem, I even don't know what all this box is about.....
To assure you: this is the "best of AutoCad" but only in French ???

Hello, thanks for your reply
However, I wouldn't call it "fix-it", it has to be repeated all the way.....
I even don't know what this box is about.....
If your French is good enough, have al look on all this "best of autocad"....

@Anonymous - that DDPTYPE command worked beautifully.

Was having the issue of a jerky mouse while a command (such as "move") was active. I tried everything. DDPTYPE smoothed it all out, thank you!!!!

Thanks. No english version of this document? Can it be translated inside a a PDF??

Our office has continued to struggle with this issue.

I did find something a couple days ago that may be key info to the problem.

I had a drawing with a few xrefs that were xclipped. I unclipped them, zoomed extents, and did a regen.

The issue went away. That tells me there is a defect with the display list engine.

Its somehow choking on things that are off screen, either because of an xclip, or outside the regen area.

You know how you zoom out and it stops at some point, until you regen?

Well possibly the stuff outside that limit is not be handled right.

So what I described above is absolutely a bug. 2017 did not have it, and I'm sure if the developers read this they would know exactly what system is having issues. Autodesk does not run these things down anymore though, so no hope of that.

@JamesMaeding

Just ran across a similar thing today.

Civil 3D 2019.

Drawing has the "sticky" cursor syndrome.... (Yes, all of the normal things have been eliminated, including everything in this thread, everything in the AKN article, and everything we've learned over the past 20+ years of working with AutoCAD....)

This drawing has about 15 Xrefs. We unloaded all of them and the problem goes away.

We reloaded them one at a time, until the problem came back, and voila... we know what Xref is causing the problem.

However, there is nothing seemingly wrong with this Xref. It's a clean drawing that doesn't even have any AEC objects. It just contains polylines, lines, arcs, and circles (9550 objects total). 

The sticky cursor problem does not exist IN this drawing itself, it's only when this drawing is xrefed into the sheet file.

Still working on it. Will update when I find the cause.

[JamesMaeding]

@rkmcswain

We continue to see this, and the other day I solved it on one drawing by unclipping the xref culprit, zooming extents, then regen. Then zoom back in and no lag.

It may be a different issue, as we don't know if its one or many, but it seems like a graphics bug with acad.

Stuff outside the "visible" view, maybe the regen extents, is hampering things.

Xclipping is likely one of the first things you tried, but just saying it has been happening to us in 2018. Not sure if 2019 fixes it.

[rkmcswain]

I kept operating on this "problem" xref, doing things like removing all custom linetypes, audit, purge, used BricsCAD to Wblock the entities to a new file, etc., until it was down to as basic of a DWG file as you can imagine. None of those steps fixed it.

As soon as we reloaded this xref, the sticky cursor returned.

Finally as a last step, I simply erased everything in the drawing file, saved it, reloaded the xref, and the sticky cursor problem did NOT come back. I am not, at this time, going to try to isolate which one of the ~9500 objects is causing the problem, but it appears to be one of more of them.

BTW: This xref is not clipped.  @JamesMaeding

Just to be clear, this appears to be a DATA FILE problem, not any settings inside of C3D.
Could it still be a C3D 2018/9 problem that did not happen in earlier versions? I suppose.
But it's not the grid, or snap, or Ptype, or Selection Cycling, 3DOsnap, DUCS, or anything related to the UI.

[rkmcswain]

Interestingly enough @JamesMaeding, when I open the parent drawing in plain AutoCAD or BricsCAD (both of which include the C3D object enabler), there is no sticky cursor, with this same problem xref attached.

I realize this a not an entirely fair comparison, but what else can provide a true comparison to Civil 3D? There is nothing else you can really test against to see if there is an application problem.

Draw anywhere some points (command _point). Then start the ddptype (or ptype) command and select one of the boxes. What happens with your points? (in older ACAD versions a regen is necessary to see the effect).

Surprise, surprise ...

BTW: To get the same effects you can also change the system variable PDMODE and PDSIZE. For more detailed informations read in the Help.

Hi everyone,

I am getting completely frustrated with no success from all of your tips that apply to ACAD Architecture 2018 and from my Imaginit tech support which mirrored the suggestions from John.Vellek/Autodesk and that are in the Autodesk Knowledge Network articles. Someone out there (maybe jmaeding?) seems to be in the same boat my firm of about 30 users is in. In our case, we experience the choppy cursor in both sheet and base files, not just files with xrefs. My IT manager assures me that we have the latest and greatest graphics card (Quadro K1000M). We have the latest updates and have cleaned up our files and stripped down all of the suggested settings. Like jmaeding, I refuse to believe that we have problem files. We were working fine in 2016 for nearly 2 years as well as the older versions. This behavior in 2018 started showing up a couple months after upgrading to that release. What is the fix to this? The only file I can work in without the choppy mouse is a nearly blank basic template file that my tech support sent to me. Other than file size, I don't see what the issue could be. I am happy to share these files with anyone who would be willing to help. Ideas?

[johnw]

Try using 2019. Download the free 30 day trial if you don't plan on upgrading just to see if that works.

[JamesMaeding]

@johnw

2019 does not help, I tried it when it came out and the updates don't help either.

This is one of those deals where I believe Autodesk has lost its ability to truly troubleshoot its own program.

They may have the technical ability, but the management won't let them spend the time needed on it.

It is a crack in their foundation though, and I believe was introduced when they redid their graphics engine in ver 2017 or 1018.  They talk about faster zooms and stuff, well that sounds exactly like the problem to me - confused clipping mechanisms for stuff off screen or frozen. I think that because on some of my key tests, unclipping xrefs solved the issue. You would expect that would make the computer work harder as more stuff shows. No, acad was tripping on clipped stuff. It may be system specific too.

That 1000M video card means 1 gb of vid ram. May laptop has a 4000M on it (4 gb), and average cad cards should have that much these days. Every machine I test on at my office get same jerkiness with the problem files though.

Again, this is simply too much for the current Autodesk organization, or would they like to prove me wrong?

P.S. I tell users that encounter the issue to use Bricscad, it does not suffer from the issue, and users look at me like I did some magic. No, its just normal Bricscad speed. That is the one you want to get the trial for. I am not paid by them in any way in case wondering.

[JamesMaeding]

@tbevis

I'll test on systems here if you send me the files. PM me to keep them private if you prefer.

[johnw]

I had the same issue that I couldn't resolve, but upgrading to 2019 fixed the problem. Sorry that didn't work. Try swapping your video card out with another one to test that theory. Sorry I don't know what else I can say to help you...

[JamesMaeding]

@johnw

Interesting that 2019 helped. That shows none of us have a handle on the issue, so each team should try various things.

We are moving to 2019 soon, so will have more experiments to report back on once we do.

Hello,

I've been wrestling with this sticky cursor behavior since last Summer in AutoCAD 2018 and 2019.

I run ACAD with Hardware Acceleration off, no tweaks, and no apps or LISPs loading (pretty much all defaults except my Workspaces).

Here's the simplest of scenarios...

1. I open a new drawing with acad.dwt, which I never alter from it's installed state.
2. The cursor moves around the screen well and starts a selection window smoothly.
3. I start the line command and click a start point.
4. The cursor lags and stutters as I drag and sweep in any direction.

If I change the Visual Style to anything but "2D Wireframe" the lag is gone.

Just been dealing with it and changing to "Wireframe" when it get's on my nerves too much.

I too have been on ACAD forever and I've tried many things to get this to straighten out consistently.  If there are any additional ideas I'd love to here 'em.

Cheers,

Blaine

@beyoungjr

Do you mean you get that on multiple machines at your office? or just yours?

Do you have anything marginal going on, like 3 huge monitors run from a laptop or something like that?

I take it you tried turning off the line smoothing and other features in the graphics dialog?

[beyoungjr]

2 Win10 Laptops and 2 Win7 Workstations, all same behavior.

Great processors, plenty of memory, great graphics hardware.

Tried line smoothing control and every suggestion offered in this post and others.

One workstation has dual monitors but all other machines are single screen.

Offering the simplest example of this behavior so as to eliminate guesswork on non-default settings and tweaks.

Thanks for your suggestions,

Blaine

[JamesMaeding]

@beyoungjr

I'd be happy to do a goto meeting with you if you PM me. Sometimes seeing things in action sparks ideas.

I have 100 users so see a lot of interesting stuff, but have not seen the behavior you mention on blank drawings.

Its actually a good sign, as I have hope its settings or the template. If it was just certain drawings like us, you know its the dwg and not something simple.

thanks
