Drastic slowdown with SketchupPro 2019

Hey guys, I found the longer you use Sketchup 19 the more it slows, a quick workaround was to close and open a model, that is of course after you have all tried the options above and they did not work.

Question for the Sketchup team: I assume lag is being caused by accumulating temporary files in Sketchup, those temporary files are most likely necessary and are probably used for communication between SketchUp and Dialogs and the undo strings?

In the new version of PlusSpec I added a “Purge Temporary files” option that I have been testing and it does seem to work, if it works okay with our beta testers it will be public. image

Is the SU 2019 installation in some way tangled up with iDrive?

Now that is an interesting proposition. My desktop and all SKP files are backed up to iCloud, and my internet connection is spotty and slow often. Of course, I can’t replicate the behaviour at this exact moment which is also frustrating but lends credit to the idea of it being related to my connection and iCloud somehow. I will move the file to a drive that is not synched next this occurs and see if it has any effect. Thank you!

Are you saving the SKP files directly to iCloud? Or opening them from there? There have been numerous reports of issues related to on files saved in cloud locations because of long access times. Slow downs are common and sometimes users have reported files getting corrupted by the transfer process. Best practice seems to be saving locally on an internal drive and only syncing out to the cloud.

My desktop, where I store all my work stuff is synched. Constantly updates changes, but I open them from the desktop.

I had the same problem on the first file I used in SU 2019. Small file, very basic. I tried to persevere but got frustrated and gave up. I am now back to SU2018 which runs fine apart from the missing images problem which prompted me to upgraded in the first place. I am worried now that I will have to subscribe to their new pricing structure once SU2018 becomes too old to handle new CAD files. Very worrying. We should not have to jump through a thousand hoops to make a new version work properly.

So I just confirmed it is not cloud related. It happened again so I moved the file to an un-synced folder, rebooted, cleared the PRAM and turned WiFi off, it had no effect on the behaviour which is the same as before. Hangs for 1+ min with 2019 when I try to change an attribute of a dynamic component. If I save as a 2018 file and open it in 2018 there is absolutely no problem, it functions as it should. So what got broken in the 2019 update and can it be fixed? I can’t reasonably use 2019 like this, frequent updates were a feature of the subscription pitch, so fix it please?


Thank you for your persistence on this. I don’t have much time to mess with it, so am just suspending my SKP work for now. I work via Dropbox, and of course immediately
tried w/ local files, with no effect. I’m on an Educator’s license via Trimble, and suspect that is part of the problem, although it runs fine on the same license with a new laptop.

Maybe we can get them to allow a roll-back subscription, so we are not forced into 2019.
