I've imported an 140x100mm,Acad2007 DXF file into 7.2, the design is for a single layer copper board. I've removed Acad's solid hatches but the some holes ('donuts' to aide drill centering) have appeared as a half filled semi circle.
I don't need a schematic, or similar I just need to produce a Gerber file for production from a manually drawn layout.
How do I do this? I have reduced the thick lines around 'my' tracks to 0,0. so how do I copper fill my weird and wonderful shapes that I have had use to make up a relay board with fuses which has to fit around existing 'things'
I have included a small section of a screen capture as an example
Secondly, is it possibly to undertake a manual design without nets or a schematic?
