I am a rookie, just started to learn PCB drawing, using Altium Designer 13.
I had a problem: I had to drill a hole in my board, just a physical hole, without electrical properties, not the kind of pad.
At first, because I didn't understand, so.
1. I drew a circle on the schematic Drill Drawing layer to represent the drill hole, but after generating the PCB, I found that the line had passed through the location of the drill hole. I judged that the system did not regard the circle I drew as a drill hole, so it took the line from the position of the circle.
2. I thought it was the wrong layer I chose, so I drew the same circle on the Drill Guide layer. After the PCB is generated, the line is still through the location of the drill hole.
At this point, I do not understand, the schematic only these two layers in the name of the word drill, why I painted circles in both layers, or did not generate boreholes.
Therefore, I would like to ask all the experts:
1. What layer should the drill hole be painted on?
2. Do you only need to draw a circle to drill a hole?
