Difference Between Add--Circle menu and Shape--Circular menu when creating PCB Symbol (Allegro 16.5)

seaseng
Sorry for the newbie question but I have created a SSOP8 PCB symbol in the Allegro PCB editor (16.5) and I would like to add a small circle to the silkscreen to indicate which pin is pin 1. Now should I do this by going to the Add menu and then clicking Circle or should I do it by clicking Shape and then clicking on Circular? What is the difference between the two? Furthermore, this is a top layer footprint and I will be adding the circle to both the Package Geometry--Assembly_Top and Package Geometry--Silkscreen_Top subclasses. Is this correct? Regards

    Auto Silkscreen will only copy Lines and Text to the Autosilk layer, that is why the shapes (filled circles) you created are not being copied.

    The way Auto Silkscreen works it copies elements to the Autosilk layer and trim them based on the Element to pad clearance - this will not work with shapes.   Suggest making a circle with a line width to form your pin 1 identifier dot which will be copied to Autosilk.

    Hope this helps,
