AutoCAD 2019 Selection preview variable Reset Issue
Hello,
As it says in title, the variable for SELECTIONPREVIEW has a problem. It changes back to 0 on it's own.
What can I do to fix this? Is there a Service Pack or a hotfix for now, regarding AutoCAD 2019?
thanks

Hi,
>> SELECTIONPREVIEW has a problem. It changes back to 0 on it's own.
Hard to believe that a variable does that on it's own, but you can watch variables so you know when exactly (which command, which tool, which action, ...) does that.
To watch system variables please use _SYSVARMONITOR (>>>details<<<)

Sorry NO!!!
Beta software should never be installed on productive systems, never!

Hi,
It seems that preferred SYSVARMONITOR for SELECTIONPREVIEW is 3, and my current is set to 1... Why is there a preferred number at all? It's not a 0 or 1 variable?
thanks!

Every variable needs a value, for this one Autodesk use value 3 as default

In your sysvarmon you can add or remove variables like you want and your prefert value.
Sysvarmon is only to see WHEN values change.
So you know "command XY force my variable ABC to another value, nothing more.

As mentioned there's no gremlin in autocad that randomly changes settings. Sometimes a lisp will change a setting and then not change it back when it finishes running. Also a lisp can change a setting then if you cancel out of the lisp it doesn't get to the part of the code that changes it back since you ESCed out of it. I imagine there's even some built in autocad commands that don't set variables back if you ESC out of them before the command can finish running. Use the system variable monitor as suggested and you'll know the exact time it changes and then you'll know what is doing it. F2 so you can see the command line history to see which command did it.

apparently there is a gremlin in my autocad LT 2020 [with no lisps of course].
here's what i got when inspecting the command line as suggested:
Command: OFFSET
Current settings: Erase source=No Layer=Source OFFSETGAPTYPE=0
Specify offset distance or [Through/Erase/Layer] <144.0000>: 12
Select object to offset or [Exit/Undo] <Exit>:
Specify point on side to offset or [Exit/Multiple/Undo] <Exit>:
Select object to offset or [Exit/Undo] <Exit>: *Cancel*
Command: DIST
Specify first point:
Specify second point or [Multiple points]:
Distance = 40.0392, Angle in XY Plane = 357.5, Angle from XY Plane = 0.0
Delta X = 40.0000, Delta Y = -1.7717, Delta Z = 0.0000
Command: DIST
Specify first point:
Specify second point or [Multiple points]:
Distance = 15.0107, Angle in XY Plane = 87.8, Angle from XY Plane = 0.0
Delta X = 0.5675, Delta Y = 15.0000, Delta Z = 0.0000
**** System Variable Changed ****
1 of the monitored system variables has changed from the preferred value. Use SYSVARMONITOR command to view changes.
Command: SYSVARMONITOR
Command: SELECTIONPREVIEW
Enter new value for SELECTIONPREVIEW <0>: 3
**** No System Variable Changed ****
so i get the message that selection preview has changed [on its own cause no reason]. i change it back from 0 to [preferred, just as i had it set] 3. and i get a prompt that no, it wasn't changed?
WTH?

the autocad desktop app only says i can upgrade to LT 2021. no new things for 2020. is that what you mean by updates?

You probably don't want 2021 just yet, we real-world users haven't discovered all of its quirks just yet... .

where would the ABOUT window list those things?
mine only shows the product version and in the scrollable section it has autodesk and third-party trademarks. plus the manage license button.

too late...
i was upgrading it as i was writing.
as in the post above, i only have the version of the autocad in my 'about' window and the manage license button. and those texts that say nothing about the upgrades or anything. and it was just the same before upgrading.
