DXF - problem with import into PCB, where are my nets - and what are nodes ?

[Nick Mulder]

Hi,

I have gone through the DXF 'getting started with PCB design' .pdf with flying colors and decided it was time to create my own cct and PCB...

It was a little more complex but really nothing more in terms of using the application - at least i thought...

Once I have compiled the schematic (no errors) I head to the PCB file and click on Design - 'import changes in MC3.PRGPCB' - I get the same screen as I did in the tutorial but the nets are not listed, they are replaced instead with a list of 'nodes' -

Clicking on 'validate changes' will get a red cross next to all of them and 'Executing changes' gives me nothing in the PCB and the example error:

"ECO Action Failed A4 test pcbDoc|PCB|Add Components|Add|R1|To|A4 test pcb.PcbDoc|R1 to A4 test pcb.PcbDoc"    >>ok<<

for all the components listed  ...

Any idea what I need to know/change  ???

Still learning... 

'node' isnt in the Altium index :-\


thanks for any help,
nick
