Another trial: I opened the drawing in NanoCAD and tried to delete the "sideview" layer to see if it would crash too or not. NanoCAD refused to delete it:

Apparently the layer is not really empty.
So I switched off all other layers and saw this (part of screen):

Looks like the main dimension lines.
They could not be selected by mouse-click. Select all worked and following erase all.
But upon switching on the other layers everything was gone.
