I can see the discussion here:
https://easyeda.com/forum/topic/Exporting_with_assembly_drawing_causes_missing_traces_on_layers-PGqWsmga4
But I can't see how to repeat this: i.e. to see the silk screen plus pads only. Could you provide a step-by-step description? Is there already a tutorial on assembly drawings?
Even if I can replicate this example it is probably not what I want. I need an assembly drawing separate from the silk screen. I can see how to turn on the "TopAssembly" layer and I can draw on that manually (adding "Tracks" to create component outline and "text" to add the component idents). What would be perfect would be to copy the silk screen layer onto the TopAssembly layer then edit the TopAssembly layer. Is there a way to do that? If I try copy and paste I get the whole component copied...
