Tested it on electrical schematic drawing which has one page on one layer. Normally on other CAD systems I set only one layer visible and rest are set off to see one page. But nanoCAD (see the version from attached print screen) shows stuff also from layers set off. Here is same file opened into nanoCAD and DraftSight and both are set to show same layers, but output looks weird.
