In version 7 if I went to schematic, took a component and pressed E, modified the footprint, in the window that opened, there was an icon to see it in 3D, it seems to have disappeared now.
I think this feature or something like it should be in 8.0.1-RC which was announced some moments ago. Browse today’s topics.
Edit: do you mean this: Footprint Chooser missing 3D model view button (#16173) · Issues · KiCad / KiCad Source Code / kicad · GitLab ?
