How can I design a single layer board in Ultiboard?

[Wes_Plybon]

The students I work with design some very simple boards and we want to make them single layer, mainly because we etch them ourselves.  Is it possible to set-up Ultiboard to route on a single layer?

Ultiboard always has at least two layers, but you can turn off routing for individual layers. You will then get DRC errors for any copper on the "off" layers.

1. Open the design
2. Click Options > PCB Properties and select the Copper layers tab
3. In the Allow routing box, change the layer name Copper Bottom, and click Properties
4. In the Copper Layers Properties dialog, uncheck Routing. It should look like the image below
