While Sketchup Pro has been great for relatively simple objects, I am now creating very complex objects and Sketchup Pro 2021 is constantly crashing and refusing to 3D export. For a while I could export in OBJ but not STL. Now I can’t do either. It feels like I have outgrown the product. This may be a Mac only problem, by the way. I have uploaded the current version of the file. I am only exporting one of the two objects at a time, either by hiding one or just exporting the selected object. Can someone on a Mac try this? I am also crashing the program frequently using solid tools with these complicated objects. These are to scale but I am designing at 8x. I can’t export at either resolution.

Interesting. So this may be a Mac only problem. The threads are not standard. The two parts just need to mesh. Thanks. ---

> [@Choclit99](#): > > Interesting. So this may be a Mac only problem. I don’t think this is a Mac problem. On my Mac I was able to open and work with your file without crashing and export both of your pieces as .stl and load them into Cura for printing just fine. I generally do not experience much crashing of SketchUp or Layout on Mac. This might be a problem with your specific installation or a conflicting extension, is SketchUp loaded into the applications folder, not running off the desktop? > [@Choclit99](#): > > Can someone on a Mac try this? I am also crashing the program frequently using solid tools with these complicated objects. These are to scale but I am designing at 8x You might be running into the tiny geometry issue when using solid tools on such small geometry. SktechUp has a lower tolerance of about .001", edges smaller than that such as are created in tiny radius curves cause errors and prevent faces from forming, it could also be causing crashing if you are running out of ram in calculating the number of edges created in a complex solid operation, although the edge count for this model is pretty modest at around 50k. General best practice for 3D printing is to model at 100 or 1000x scale. I model in M and treat them as MM, many others do the same. With this practice I never have issues making any type of complex geometry. .STL is a unit-less format, so the actual units used to model is not recorded in the file, what matters is the unit set in the import process into your slicer. I leave my SketchUP model in meters, export as-is without any scaling, and have set Cura (my slicer) to read all .stl files as MM so there is no scaling on either end, things just appear in the slicer at the correct size, this is a common workflow. > [@Choclit99](#): > > and refusing to 3D export. > [@Choclit99](#): > > or just exporting the selected object. The 2021 release of SketchUp introduced an unfortunate Bug which causes the Export Selection function to fail, in any file format. There is no error window, it appears to export, but no file is created. You cannot 3D export a selection only until this is fixed with a new release, no telling when that will be but the SketchUp team is painfully aware of the problem. For now you can copy paste to a new file and export, or download the [STL export extension from the SketchUp team](https://extensions.sketchup.com/extension/412723d4-1f7a-4a5f-b866-281a3e223337/sketch-up-stl) which will restore the export selection function through the file menu. ![Screen Shot 2021-05-28 at 10.13.17 PM](https://global.discourse-cdn.com/sketchup/original/3X/5/7/573feca5c716f120a7201e7d3c26b8ab56874f81.jpeg) ---

Lots of helpful stuff here. The export failure is exactly what you are describing. It partially goes through the motions but doesn’t generate the file. I will try the export extension. I didn’t know about that. Thanks! Interesting comment about scaling up. I have been using 4x or 8x scaling a lot since the follow tool frequently fails with small parts at scale. Going to 100x to work makes sense. I reduce to scale before exporting to CURA typically. ---

I’m using an iMac (Mojave) with SU2021. I tried your file and it crashed. > [@Choclit99](#): > > This may be a Mac only problem I also experience regular crashes with solid tools, so much I stopped using. My crashes generally occur when using extensions or on closing SU. I also regularly send reports to Apple and SU. I have not received any helpful suggestions. At one point I completely wiped the machine, reloaded only SU2021, with few extensions. The frequency of crashes went down (2-4 in 6 hours), but did not stop. I did not have this problem with SU2019/2020. As of today, I have reverted to SU2017 which is producing a stable work environment (no crashes so far ~5 hours, fingers crossed). I am adding extensions one at a time. At my level of expertise trying to troubleshoot whether the problem is hardware or software is bewildering and greatly frustrating. I’m giving up a lot by using SU2017 but a stable work environment is critical. I also prefer the Mac environment, but will probably move to Windows in the future. Looking at the prevalence of crashes being reported on this forum, leads me to believe that SU on Windows is the more stable environment. Hope your Mac experience improves … ---

Interesting that on some Macs it works and others it does not. I crash with solid tools all the time as well. All this started when I upgraded to 2021. I think I will downgrade to 2020 and see if that works better. Can I open 2021 saved files in 2020? ---

Found this on the SU website. Looks like you have to save the file to an earlier version first. > Every major version of SketchUp (eg, 8, 2015, 2016, 2017, 2018) has a unique version of the \*.skp file format. As such, the model needs to be saved in the correct version of SketchUp that will open the file. But don’t worry, you can “down save” a model so you can open the file in an older version This is what my 2017SU version save displays. Would guess your 2021 would have a 2020 option. ![save](https://global.discourse-cdn.com/sketchup/original/3X/b/7/b7dc515d20419f8c460ae9c2a64eb50e0e3c18a6.jpeg) ---

I asked @colin to look at my Bugsplats, did not get a definitive response, but he may be able to assist you. Seems to me with all the diagnostic data contained in these reports, the errors should be identifiable. ---

You might find these posts interesting, as they seem to question code quality in SU2021. If you do down grade to SU2020, I would be very interested in any changes (good or bad) with your issues. Thanks. > [@Choclit99](#): > > All this started when I upgraded to 2021 > [@SU Unexpectedly Quit](https://forums.sketchup.com/t/su-unexpectedly-quit/156052/25): > > The 15 bugsplats that you’ve sent in during the last three weeks have been for eight different reasons. More often when there are crashes it’s for the same reason each time. I can’t take any good guesses about what would cause so many different issues, so I will ask the developers to take a look at the range of issues, and see if there is something in common. To answer Mike’s question, you do appear to be running SketchUp from the right location. > [@SU Unexpectedly Quit](https://forums.sketchup.com/t/su-unexpectedly-quit/156052/27): > > Hi Colin. Yes, the “eight different reasons” (at least) has really fueled my frustrations, if you can’t already tell from my bug-splat comments confused It seems like the 21.0 release is full of problems because the various stack traces have very few similarities. I do, however, see Ruby more often than not at the top of the stack which is disconcerting. My main point to begin with was, the 3D Connexion drivers may indeed be causing problems, but I’d scrutinize crash logs before pointing that… > [@SU Unexpectedly Quit](https://forums.sketchup.com/t/su-unexpectedly-quit/156052/28): > > Try looking at 2021 fondly, that might help. The biggest change Ruby wise with 2021 is that it was updated to version 2.7. During a testing period none of the extension developers had any problems, but later on we found some that had problems with the change. Anyway, I will see what the developers say about your comment about how invalid data is handled, and if any of them are brave enough to read your bugsplat reports. ---

There is currently an issue with exporting the selection. Until we send out an update that has that fixed, you would need to export the whole model, or copy what you need into an empty document, and export it from there. ---

I’m having similar issues and it also happens when I go to export a 2D Graphic. It only started happening when I upgraded to 2021. Any ideas what the issue could be or how to fix/work around it until a newer version of SketchUp is available? ---

The log reports mention 3D Connexion, but other extensions may also contribute. Reopened files appear to have saved correctly with changes intact. When I run SKP 2021 with no extensions loaded I have no issues on file save/close. I have investigated downgrading to Catalina in which had no issues but the process looks intimidating for me as I am not a sophisticated deep diver into the way the OS works.
