Gerber.cam JobforTwo-LayerBoards
The gerber.cam job uses the GERBERAUTO and GERBER drivers.
These generate files in the RS-274D format. It is set up for two-layer
boards which are to receive a solder stop mask on the component and
onthesolderingside,andistoreceiveasilkscreenprint.
Load the job by double-clicking on the gerber.cam entry in the tree view
oftheControlPanel.
In the first step an aperture table name.whl is automatically generated.

The second message advises you that more than one signal layer is active
at the same time. Normally only one signal layer is active while output is
generated. However, when generating the wheel, all the layers need to
be active at the same time in order to form a common aperture table for
allGerberoutput.

If other layers are also to be generated, e.g. silkscreen for the bottom
side, or a solder cream mask, the Gerber job can be extended as
required.

manufacturer uses the Extended Gerber format. In contrast to ger
