Function
Add drill hole to a board or footprint.
Syntax
HOLE drill ..
HOLE is used to define, for example, mounting holes (has no electrical connection between the different layers) in a board or in a footprint. The parameter drill defines the diameter of the hole in the actual unit. It may be up to 200 mm (7.7840 inch).
HOLE 0.20
If the actual unit is "inch", the hole will have a diameter of 0.20 inch. The entered value for the diameter (also used for via-holes and pads) remains as a presetting for successive operations. It may be changed with the command:
CHANGE DRILL value
A hole can only be selected if the Holes layer is displayed. A hole generates a symbol in the Holes layer as well as a circle with the diameter of the hole in the Dimension layer. The relation between certain diameters and symbols is defined in the "Options/Set/Drill" dialog. The circle in the Dimension layer is used by the Autorouter. As it will keep a (user-defined) minimum distance between via-holes/wires and dimension lines, it will automatically keep this distance to the hole.
In the layers SolderMaskTop and SolderMaskBottom, holes generate the solder stop mask, whose diameter is determined by the Design Rules.
