I am somewhat new to making PCBs and components, I am using this video as a guild to learning how to make footprints "(Please visit the site to view this video)
In the video, the first time she makes an assembly outline, she sets the class to Package geometry and the subclass to assembly_top, on the second chip however, when she draws the assembly outline, she uses the class of Board geometry and the subclass to silkscreen_top. I am not sure what the difference is, or which is even correct. Which class and subclass should be used to draw the assembly outline, silk screen, and package boundary?
