Canvas Color is white. Is it possible change Canvas Color? Why I want to know this because let we say there is an item to assemble which has many part files and sub-assembly files, to differentiate part files and sub-assembly files different Canvas Color can help.
If you are using Windows 10, and NOT using a PDM software, then you can hit the view tab and turn on file name extensions.
Part files and assembly files and drawing files all have different extensions;;
Then just sort by type.
If you are using windows 7 or something other, this can also be done, it is just slightly different. Just google how to show file extensions for your OS.
