Export to CNC

Hi

I Recieved a drawing from another user and have the following problem. I Need to export the file in DXF so I can open on my CNC. The problem is when I import all the lines are dotted lines and the circles are also dotted lines and I need to make them solid lines and raduises or full circles can this be done in Libre CAD without redrawing the whole thing ?

Select all.
Then Tools - Modify - Attributes. Set linetype, Ok.
