I’m a newbie using the free web version. I often accidentally create small lines and surfaces that I did not intend to create. These often get hidden beneath other groups and components so they can’t easily be seen. Sometimes they are really, really small so the only way to even see them is to temporarily hide all other objects and then zoom in extremely to hunt them down for deletion.
It would be great to have a command that would hide all “proper” lines and surfaces (developers can decide what “proper” means) and then display only lines not connected and surfaces not connected, so they can be seen for possible deletion, unless you intentionally want some of them of course.
Are you using groups and components? And follow that up with assigning tags to the groups or components? Then you can toggle off the things you make into ‘objects’ - select anll, and delete the other stuff.
