3.1.4. Outline
The outline of a regular symbol should be drawn with a rectangle or a polygon. All vertices should be located on the 2.54mm grid and following properties should be used:
Layer: Outlines
Line Width: 0.2 mm
Filled: no
Grab Area: yes
Special symbols (like a capacitor) might not have a regular outline, in such cases it’s allowed to use different properties to draw the symbol geometry.
