Fredo reported this a while ago. With recent versions if you have a reference set up for an entity etc and it gets recreated - e.g. during an explode - the reference changes and so there's an error as some code finds an invalid reference. Most developers have now trapped for this in their code - e.g. setting a reference to an entity does not persist after an operation like explode, so you need to grep the result of the explode to re-collect the object[s] to re-find that entity - using persistent-id or a custom attribute assigned to the entity... In older versions an explode etc did not destroy the reference to an entity, so your code could reference it inside a group and find it again after the explode... the persistent-id changes broke this and a workaround is needed, as explained. I suspect that the old DC code has not been fully updated to avoid the 'delete entity' reference messages... It's a straightforward fix to trap for it - but SketchUp seems unwilling to devote much time to DCs - they have new fish to fry...

This happened to me too since 2019. I think it is a sneaky bug that just got in and no one hardly noticed, but yes, Isometric views export to DWG or other line software aren't up to scale. I use it often to to Iso views in my 2D cad drawings, and they aren't to scale since the 2019 version, they used to be before. At first I thought it was some plugin issue (because I use a lot of them and I sometime encounter compatibility problems, but I did a few clean re-install since and it was there nonetheless. I just kinda live with it now

UPDATE this a chronic problem with the right mouse button click to save changes to componenent or group edit.I have done 2 installs, but when I uninstalled I guess it didnt do a complete uninstall because with the new install, the extensions prefernces and such that I had loaded came back rather than a fresh out of the box do-over. which if or the most part okay cuz I dont like re-loading all of that stuff. Funny. . .This was working fine yesterday, and I am not sure if I have a conflict with an extension. I hadn't loaded that many. Just enough to get me up and running in 2020. I unstialled most of them other than the "commercial" ones, etc. I dunno. If anybody out there has some ideas, I'd be grateful. D

I drive drunk all the time but have never crashed, therefore proving that drunk driving is not only ok it is in fact safer than driving sober. People that do crash while driving drunk must have done something to their cars to make them faulty.

@jga said: @n3to said: ...have the inserted files into components or group as was before? I have to admit I never noticed there was a change in behavior. Can you not just insert the drawing, then drag it into the group/component using the Outliner? Yes, is it possible also. But in the precedent version it was automatic. If I'm working inside a group, the DWG as inserted inside this group. 2 steps less... N3TO

IDK maybe file size is a trigger..

The ExtensionStoresup3 uses the older style WebDialogs for its dialogs - for backwards compatibility. These dialogs need Internet Explorer to make them. If [as you appear to say] you have 'uninstalled' Edge you've probably broken IE at the same time ? Although you might not use IE for your day-to-day browsing it is vital for SketchUp's correct functioning... Once you have IE set up you need to check your Internet Options [Control Panel]. This should be set to use Medium/Low for Local-Security and in Advanced styles/control etc and scripts etc should be allowed to run unhindered. Because the dialogs are populated using javascript links between SketchUp and the dialog's HTML I suspect that the plugins-folders are not being listed in the dialog because the page's javascript is blocked... hence the 'security warning' ??

Which version of 2020? I just did the same thing you showed and with the default export settings. Attached is the PDF I got using SU20.1.235. [image: oWVY_Screenshot-7_9_20207_56_40AM.png] Untitled.pdf What graphics card are you using? BTW, your profile says you're still using SU2017. Perhaps you could update it.

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? @cotty thanks for Link posting Rosketch

@markchandler said: 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 !
