Incorrect re-saving of the drawing from SLDDRW to DWG in Solidworks 2012

Hello!

A drawing was created in Solidworks 2012.

Then it is re-saved in * .dwg format using the "Save As" command. But when you open a saved file in Bricscad, the drawing looks like this:

All sketches are hidden in the model.

1. How can I fix this?

2. How can I move all views into a one layer in Solidworks 2012 and transfer the elements which don't need for output to another layer?

Thank you!
