I’m using V5 and trying to understand what I am looking at when I see a pad on the screen. Also how and where changes can be made (globally / locally)
I’ve opened the V5 lib footprint: R_0805_2012Metric
The inner rectangle with square corners = copper pad
Not shown is the mask which is the same size as 3) below but with square corners.
An outer rectangle with rounded corners. I can’t identify what this represents. At first I thought it was the clearance zone it doesn’t change with changes in clearance.
If I run a trace from a non-related net near the SMD pad it will get no closer than the rounded cornered rectangle (0.2mm)
However, If from the Pcbnew tools (setup/DesignRulesEditor/Net Classes editor) I change the minimum pad clearance from 0.2 to 0.5 mm the rectangle with the rounded corners does not change shape but now I can only bring the non-related trace to within 0.5mm
So is the rounded corner rectangle the clearance zone but doesn’t change with clearance or is it something else?
