just turn your antivirus virus protection off and see if its works.

I ended up uninstalling and reinstalling and it's fine now. Just weird I guess.

@Box
thanks for testing...
do you think, Trimble knows and will solve the Problem?

We've reproduced this with 2019 and 2020 and are opening a bug.

Thank you for looking into this. It's caused me some grief

Ensure that the main SketchUp.exe properties are NOT set up to 'always run as administrator'. This can cause issues since SketchUp is then running at an elevated security setting and lower operations via Windows Explorer can't affect SketchUp.

Also ensure your SketchUp installation is correct...
Whilst logged into Windows as your usual user-account, ensure SketchUp [and Layout] is closed.
Find the SketchUp installer exe file - typically in your Downloads folder.
Select that exe file's icon, right-click > context-menu > "Run as administrator"
When prompted choose 'Repair' [or 'Install' if it's a brand new installation].
After it completes restart SketchUp and see if that helped...

Installing any complex app from its exe file in any other way can lead to unpredictable issues.
So never double-click the installer's exe file to 'Run' it.
Even if your normal user has admin-powers it's NOT the same as doing it as outlined above.

Doing a Repair leaves all of your installed Plugins alone.
Very rarely it can cause issues with some Extension's [un]saved preference-files/folders that have incorrect permissions set, even after the Repair - if you experience those issues we can advise on a specific fix if needed...

Unfortunately we here are like you, with no direct knowledge of the dev-team's work.
It appears that it's a longstanding issue, but there is now an official bug-report lodged...
Although I just checked up on it and no one from the dev-team has looked at it yet, and there's another report about something else ahead of it in the queue too !
So I don't expect an announcement of a fix anytime soon...

Thanks... I must have done something right the problems has disappeared (for now)! I will check with NVIDIA on recommended settings for additional monitors... they advertise this card model as being able to handle up to 3 additional monitors...

Thanks for you quick help

Cheers
David

Thanks and Prima Juju 👍 this comes out clean, smooth and soft like baby skin 😄 - thanks for this way that was not in my mind so far. Now I just have to figure out how to do that in my video editor 😄 I´ve never used this technique before

If you let me know your email I can search for the crash reports.

Il ne suffit pas de reculer la caméra et de changer l'angle de vue ( avec l'outil Zoom : et rentrer une autre valeur dans la boîte tout en bas à droite) ?

It would help if you attached the model so we can check it just in case it's something wrong with the model itself.

Please post this kind of specific question in a relevant thread.
The CutNfill thread already contains several posts about why two seemingly solid objects subtract to give a non-solid, which in turn reports 0 volume.
This is not a limitation of the tool itself, but one of SketchUp's built-in methods to manipulate solids.
If the subtractions leave tiny edges SketchUp faces to form the related faces in the results, and non-solids can't have a volume !

I checked the .dwg file and when regenerated, the linework intersects in those locations, however, there are gaps when the circles/arcs are simplified graphically, even when using autocad. So, there is an issue importing these elements

I did try Didier's projections and Thom Thom's edge tools and still having a heck of a time getting faces formed. Even drawing new lines/edges is not helping.

Are there any tricks in prepping the .dwg prior to import that will help?

Very good. Not sure why the problem but it shouldn't be a problem now. 😉

Which graphics card is being used by SketchUp? Changing cards might fix it. Keep in mind that Sketchup 2019 doesn't support the OS version you are using yet. The SketchUp folks recommend not upgrading at this time.

Thanks for chiming, TIG
Yes, the planes were on the ground plane; I never thought to check that!!! I guess I've always started generating line work on the ground plane and wasn't aware that even when hidden style is active, two or more planes won't display...

I know what I'll do from now on; set my floor level above the GL.

Easy fix. Thanks again. 👍 👍

When you say your "account is admin", do you mean your normal Windows user account has admin powers ?
That's not the same as running SketchUp while logged into the administrator account, which is a different animal ! and should be avoided...

And of course, while logged-in as your normal account you need to do the right-click on the installer's exe and 'Run as administrator'.
Otherwise the files/folders installed by SketchUp for its own use, and for your use as 'user' will get unexpected permissions and cause issues...

Assuming that your error message is much the same as previously reported - albeit for v2018, when you quote v2019 ? - then something is preventing SketchUp from copying its 'Shipped' extensions from its main Program Files folder to your user Plugins folder in the AppData path...

Good luck.

I think if you are still seeing crashes, Vray is the next suspect. Other people have reported issues with Vray so it's a good one to check.

As Didier says, if you have not installed SketchUp correctly all kinds of unexpected file & folder permission issues can appear...

To repeat what has been stated in many places before...
To fix your installation...

Login to Windows as your normal user-account [NOT the specialized administrator account - BUT if your normal user has some admin-powers that is OK]
Ensure SketchUp is closed.
Find the SketchUp installer's exe file - usually in your Downloads folder.
Select its icon, right-click > context-menu > "Run as administrator"
When prompted choose "Repair".
When it completes retry SketchUp and see if these kinds of issues are improved...

Excellent on the driver update thing. I'm glad that helped.

We had a lot of snow back in February and March. I'd have gladly shipped it to you if I could.
