How to produce an assembly drawing
A traditional assembly drawing corresponds to the information which most engineers would place on their silk screen, plus an important extra - the pads. The problem is that there's no obvious method to include these when using the plotting dialogue, so this FAQ addresses how to achieve this.
There are two ways to do this, a quick and dirty way, and a less risky way.
Firstly, the quick and dirty way (with your design open) is to go to [Settings], [Design Technology] and look at the 'Layer Types' tab. Edit the 'Silk Screen' layer type to include all pad types you want in the assembly drawing, usually all types except vias. In the output dialogue, select the top silk plot and merge it with the board outline using the 'Layers' tab. Output the assembly drawing, but remember to use the undo facility to restore the silk screen layer type to its correct state afterwards.
The better method long term is slightly more work, but is less error prone. Again, go to the 'Layer Types' tab, but create a new layer type. This should be essentially a copy of the 'Silk Screen' type, but with the appropriate pads included, so it will match the modified silk screen type produced using the first method. Now create a top side layer using this layer type. This will include the pads, but not the silk screen information as this will still be linked to the original silk screen layer.
To create an assembly drawing, it's only necessary to merge the board outline with the top silok screen and this new layer. If using a job to record this, you may wish to create a new assembly plot using these settings to keep the plot at arms length from the true silk screen plot.
