file in IPC-356
i sent these to my manufacturer and he Gerbers are ok except
Strictly speaking, the board outline is the boundary between the edge of your board and the rest of the universe, so it has a width of 0. When you send this to output, you need to set the Undefined Line Width for the Film to get the 0 width of the boundary overridden to "something" that gets plotted in the Gerber data. As a conseequence, you probably want the Board Geometry / Outline to go to its own Outline film. (You could set an Undefined Line Width for any film but this might not be great if there are any 0 widthlines lying around)
For version 16.5 onwards, Tools>Cross-Section will get you a cross-section generated from the layer data in the design cross-section. You need to use some PCB SKILL function for previous versions, search the PCB SKILL forum if you need this.
In reply to oldmouldy:
yes that is what i forgot to do regards the undifined line width. thanks
and thanks for the 2nd part also version16.5 onwards , Tools>Quick Reports> cross section did the job.
thanks again for the help.
