I’m finding in the current release build of Enscape 3.4 I’m getting a crash when I right-click a component to save as an Enscape external model I get an immeadiate crash.
Yeah, unfortunately, we have some legacy projects that don’t work well with 2021 and are much less stable when upgraded (SketchUp issues not Enscape). 3.3 seems to be working just fine, however, so I’ll continue with the older version for now and hopefully it will get addressed in some future build. Ill have to test in 2019 to see if the bug persists there as well.
As mentioned by my colleague just above, you’re using SketchUp 2018 as well which is not supported anymore. If you have the chance, you can of course upgrade to SketchUp 2019 or beyond.
