I am having a problem with Ulitiboard 8. After exporting gerbers, the board outline gerber shows all drilled holes (except for the vias) as well as the usual outline. Previous versions only exported the board outline as expected. Is this a bug, or have I missed a control option somewhere? Thanks

Hi,
I just tested this in V8 and I don't see a problem. The layers I was looking at is the copper top and the drill file, I see it in a Gerber viewer. What layer did you look at?

Hi, Thanks for response. The problem is on the Board-Outline layer only. All other layers seem OK. I expect the board outline layer to have the board outline only for prodcution of the board shape, but it also has the drill holes for all except the vias.

Hey there,
Are you able to post up here one of your files? I'd be glad to have a look at it for you if you do so.
You will need to zip the file though, the extension isn't friendly with this forum yet.
Thanx

Hi,
Thanks for reply. I have zipped and attached a simple layout. I have included the gerber that shows the problem. Very interested to see if you get the same problem.
Thanks

Hi,
Yes, that's what I see. It's the holes that I am questioning. Previous versions had no hole, just the outline. Are the holes intended to be there? Didn't get them with Ultiboard2001 (see attached gerber for earlier version of same design made with Ultiboard 2001).
I'm not certain, but I think this will upset a manufacturer using this file to give the mechanical shape of the pcb. The machines maytry to cut out the holes as well as the board outline??
Thanks again

Hi,
I think you are referring the fuducial marks, select Option-->Preferences-->PCB Design, uncheck the "show fuducial marks" and export the outline again.

Hi Tien,
Thank you for your reply.
It is not the fudials that I am refering to. I have already tried deselecting fudials.
If you could have a look at GerberHoles.jpeg posted by AdamB of NI, you can see (1) the big green hole in the middle which is a hole component. (2) the four green holes on the RHS which are a thru hole module (3) the 2 holes at the bottom which are an LED, (4) the 2 holes at the top RHS which are a switch component, plus several other holes. These are all components.
These are on the board outline layer!!!! Maybe I am mis-understanding something, but I am expecting the board outline layer to show only the line that represents the perimeter of the pcb - no holes for components?
Thanks for your help.
Mac
