I am using DraftSight V1R4x64 and I assume it is the free version without a lot of the bells and whistles of the professional version.

I have three major issues with it:

1. I am trying to set drawing limits and it will not allow me TO DO SO.
2. When I set up multiple sheets in a drawing and then save, close, and re-open the file, the tabs have all been removed.
3. When I set a layer to 'non-printing', the setting is not retained when I re-open the file.

Do I need to upgrade to get those functions?
