In 2023 i cal click select but there is no drag box select showing or selecting - it works fine with 2022 and 2016 so I’m not sure if its a command unclicked somewhere - new install today so fresh set up
Your profile shows you are using Windows 7. Is that actually correct? If it is, keep in mind that SketchUp 2023 doesn’t support any Windows versions before Windows 10.
Are the graphics drivers up to date?
This is what I see when dragging selection windows in SU2023 on my machine.
That must be it 2022 has no issue will stick with that on this machine as its needs the older OS for some other programs
