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.

Maybe tomorrow for a go to.

I'll PM you

Hi @beyoungjr,

I have seen similar comments over the past couple years and there are obvious things to try such as DUCS and selection preview and such.  Have you tried turning off the Roll over Tool Tips?

@beyoungjr said he tried all that was mentioned. This keeps happening where experienced users get on and complain about this issue, then adesk jumps in and asks us if we turned snap off.

Its deeper than that, and given that adesk made serious changes to its display mechanism around 2018, why would it not suspect bugs with that?

As a programmer, when I see a clean environment fail, I call that person immediately to troubleshoot. Its a golden opportunity to isolate an issue. Has adesk thought about screensharing with @beyoungjr? How about reaching out a bit, instead of making us do a support request that takes 2 days to get a reply?

Hi,

>> I've been wrestling with this sticky cursor behavior

>> since last Summer in AutoCAD 2018 and 2019.

Before starting with a remote session try to disconnect your workstation from network, so it can't find server, printer, Internet, and then try AutoCAD again (in case of network license use the borrow license feature for that test).

I have seen sometimes a lot if network traffic starting and disconnecting the workstation from the network helped to isolate the issue.

Of all the likely causes, I would rate that the most likely. @beyoungjr, I had an issue with an employee at a remote office, where a support path pointing to our server caused major weirdness.

I had not mentioned this as @beyoungjr said his setup was generic. However, even windows printers could muddy the waters. The funny thing is disconnecting from the network might actually make things worse, so its not trivial to eliminate all outside things windows is looking for.

Along those lines, I have noticed shortcuts and the start in folder can mess up acad.

How this would affect drawing a line is beyond me, but given we are dealing with a blank drawing, and that all machines at the office behave the same, that points to a system wide problem such as a printer that was decommissioned...

@Alfred.NESWADBA great suggestion! Why no one suggested it already, I'm not sure with all the "great" minds working on it. It's funny how people are so willing to blame Autodesk before eliminating the extraneous variables. Just stuck in the box, I guess.

[JamesMaeding]

@RobDraw

Trust us, should we discover autocad is majorly misbehaving because of some printer issue, we will blame Autodesk.

I don't want to give the impression that we are trying to let them off the hook.

[beyoungjr]

Hello Alfred,

I do not have any network resources or settings linked into my laptops, only a wireless printer with no special settings.  The printer driver is assigned by Win10 and AutoCAD 2018 and 2019 ha sit in the list as normal.

As stated previously, I startup ACAD and open a new drawing the the un-altered acad.dwt template.  No apps, addins, or scripts load that were not part of the default install.

As soon as ACAD has the clean grid displayed the cursors moves smoothly and pre-selection windows generate smoothly.  If I start the line command and select a start point the cursor lagged painfully unless I change to any Visual Style other than 2D Wireframe.  It smoothed out for all other styles.

Although I'm sure I have been disconnected at times already, I flipped off my WiFi switch just to rule out any network related issues and Started the process over.  Same effects.

I decided to reset the default profile, as I've done prior, and everything improved.  This makes me confused because that was always the first thing I tried.

I went to another workstation and reset the default profile without turning off the WiFi.  This didn't help, so I shut it down, turned off WiFi, rest the profile, and voila!  Worked!

Why would a profile have worked differently with WiFi off?  Makes me suspicious of Autodesk 360 being connected with WiFi on.  I had disabled 360 in the past with no help but not sure if I reset the profile as part of that routine.

I'm calling this attempt "no 360 connection, no network, default profile reset... fixed" (2018 & 2019 resets).  Still smooth after WiFi back on too!

I feel pretty good about this but will report back if it returns and I'll watch for symptoms.

Thanks for your help and the rest as well,

Blaine

Hi,

>> Why would a profile have worked differently with WiFi off?

Some paths pointing to network and to Internet are then not in the list of used paths and so do not need to be checked for each start, for each command, for each click (AutoCAD is phoning home sometimes, even if it seems not to make sense, line when moving the mouse to pick the endpoint of a line).

E.g. I remember that users who have added a support path to a path on the network (e.g. T:\CADTOOLS) list this path when they started AutoCAD and the server was not active, so "T:" could not be found ... and to avoid that AutoCAD always searches for T: it was removed from the list of active support paths.

Similar to that there are a lot of paths where AutoCAD searches the WWW like updated graphic drivers, available updates, and I'm sure a lot more we all don't know. Having WLAN turned off while the secondary installer is preparing the profile could be a big advantage as all these "phone home" tasks may be blocked later when AutoCAD is starting/working.

But my biggest compliment, I have not had this idea ever to run "reset settings to default" while WLAN is turned off, that could be a great suggestion for similar new threads. 😉

Thank you for that idea!

@beyoungjr

very interesting. I hope autodesk is listening to this, as they only want to increase your reliance on connections to the outside. That is ok as long as it works....

Hearing what happened, I would be most interested in:

1) any support paths looking to drive letters not on your machine (can't imagine you have any)

2) any of the features that require sign in.

We disable the info center in acaddoc.lsp:

(vl-registry-write (strcat "HKEY_CURRENT_USER\\" (vlax-product-key) "\\InfoCenter") "InfoCenterOn" 0)

3) any of the default add ons located in C:\ProgramData\Autodesk\ApplicationPlugins\

rename all those folders to .old, and unload any menus from them

Also, if you turn on wifi and tether to your phone internet, does that help?

That will eliminate any screening done by your work's internet, and is a trick I have to do to get infraworks to open some days.

[beyoungjr]

I'm emphasizing DEFAULT install with NO TWEAKS here.  Absolutely no alternate paths set.  No tethering to devices in our shop.

In teaching I developed a strict policy of keeping my system "out-of -the box" as much as possible because I could never rely on the IT department to setup the campus PC's correctly.  They barely get the default install running right and every year a new release and install.

When I need an app loaded or other useful things I unload after to remain at baseline.

I really think it's the 360 sign-in active due to the deskptop app connection to internet, while performing the profile reset.  As you said, too much connectivity.

I'm smoothed out for now but if it starts up again I'll try to get back to investigative mode.  Been avoiding it by jumping out of 2D Wireframe but good for now.

@beyoungjr

that infocenter off code I posted will kill that sign in stuff.

[Anonymous]

have this problem in both 2018 & 2019 versions.

it happens on one drawing with xref, once the the xref is removed, the problem went away by itself.

on another drawing with xref, scale converted from metric into imperial, big problem, tried everything suggested herewith, no improvement.

[ciganek]

toggling DUCS off (F6) worked for one workstation here.

[Anonymous]

Thanks your suggestion, but doesn't work.

[JamesMaeding]

@Anonymous 

if detaching the xref stops the jerkiness, copy that xref for backup, then erase more and more stuff from the original xref (reload after) and see when things behave. It will take several tries but you should be able to isolate the cause this way.

[Anonymous]

Hi, thanks your suggestion, but that sounds a lot of back & forth, tedious trials & errors.
These xrefs, were believed to be a dwg generated from Revit models.
Would like to know, whether, or:
It is problem in the drawing file itself;
Bugs in the AutoCAD program;
Not enough memory, or processing power (Dell T5600 on Windows 7, 32 Gb, NVidia Quadro 600 graphic card, dual monitors);
Any benefit adding a second Quadro card(same specs), or replacement with a new card?
Appreciate any suggestions, ideas.
Cheers

To see if it's the program or drawing should be simple. Just open up a new drawing and see if you have the same problem. Also, make sure you have up to date video drivers. Windows 7 may be a problem getting the most current drivers, but check for updates anyway.

[RobDraw]

You have a problem with the XREF file. Hardware might make the problem less annoying but doesn't fix it. Not addressing the actual problem won't make it go away. If not addressed directly, it could get worse as the drawing is developed.
