EasyGerb

EasyGerb allows you to export Gerber files while inside AutoCAD. This application is quite easy to use; simply select any object, select the output folder, and save Gerber files.

You can customize the output settings, layers, PCB mode, etc. When EasyGerb has finished the conversion, a report dialog displays the count of entities converted, location of the gerber files, and warnings (if any).
