DrillPlan
A drill plan can be printed which enables you to check the drill holes
and their diameters. It shows an individual symbol for each diameter.
EAGLE uses 19 different symbols: 18 of them are assigned a certain di

ameter; one (Ø) appears if no symbol has been defined for the diameter
ofthishole.
The diameter symbols appear in layer 44, Drills, at the positions where
pads or vias are placed, and in layer 45, Holes, at the positions where
holes are placed. These layers must therefore be active when the drill

The relation between diameters and symbols is defined via the Op
