drc error

[Paul-a]

ultiboard V10.1

Every ultiboard drawing I have made so far.

Every Copper bottem line I make gives me a drc error.

 The object "Trace: Width(0.700000 mm) Layer(Copper Bottom) Clearance(0.254000 mm) Net(2B) " is on a layer that is not allowed by the net settings

But at a collegue his computer: No drc errors. 

I must have changed some settings, but I don't know where and when......

All the drawings dind't have this problem before.

In the spreadsheet view, you can choose for every net where it may be present. (see: view -> spreadsheet view).

Else you can change it in the netlist editor (tools -> netlist editor -> misc. -> routing layers)

Hope this helps.

it realy was helpfull, but is there also some kind of setting in multisim?

To disable this when I export my netlist?

[willyp86]

As far as I know, there is no setting for it. I always have to set the right config in the PCB view.

Hi Paul,

There were some issues with the in some versions of Ultiboard. I believe this was fixed in the update for 10.1 (10.1.1/10.1.372). In these versions, Ultiboard would not interpret a blank routing layer correctly during annotation.

The solution, is to ensure that in then Multisim Spreadsheet Nets tab, that the Routing Layer column is blank.

I've managed to get the update 10.1.372.

But now I open an old ultiboard drawing, a lot of bottom copper lines gives an drc error.

Do I need to edit all these lines (like 50+) to loose the drc error?

Or is there in this version an option to select all lines and choose "apply to all layers".

 Spreadsheet view --> Nets --> Routing Layers, all of them are "10", but must be "11".

Or 

 Tools --> Netlist editor --> Misc

Hi Paul-a,

You can select the relevant nets (rows) in the Spreadsheet View and edit the routing layer for them all at once.
