Laurie,
        Can't answer your GND query.

        Why would you be using netnames to label pins "NC" or "0"? We do 
similar things here but we use simple text (annotation in Altium speak) for 
such non-electrical/non-connect labels. The problem with using a netname is 
exactly the problem you are seeing, a netname will electrically connect 
together similarly labelled pins.

Subject: [PEDA] GND Net gone


I have been using Altium Designer DXP 2004 with SP4 on Windows 2000 but 
recently had to change to a new computer now runnings Windows XP.
I have a project that appeared to be okay on the older setup but I have a 
problem with the current installation.

When updating the PCB file, having just compiled the project in the schematic 
section, the update refuses to recognise my GND nets. All the other power nets 
are listed but not GND. Is there anyway of seeing/editing/fixing the nets that 
the schematic section is working with that might explain why they are not 
showing up in the pcb?

Another minor problem is that any pads marked as NC or 0 (unsued pads on an 
SOT23 or ic for example) always come across to be joined together. Is there 
anyway of telling the system to simply ignore nets of this nature?

Best Regards

(Mr) Laurie Biddulph
