The commands DISPLAY, LAYER, WIRE, and ROUTE work only
withthosesignallayersdefinedintheLayersetup.
Further information and examples about the Layer setup can be found in
thesection MultilayerBoards beginningwithpage 121.
Loading a board file that was made with an older version causes EAGLE
to check which signal layers contain wires. These layers appear in the layer
setup.Pleaseadjustitifnecessary.
MinimumClearances
Clearance refers to the minimum distances between tracks, pads, SMDs
and vias of different signals, and between SMDs, pads and vias of the
samesignal.
Setting the values for Same signal checks to 0, disables the respective
check.
Distance allows settings to be made for the minimum distances between
objects in layer 20, Dimension, in which the board outline is usually
drawn,andbetweenholes.
Setting the value for Copper/Dimension to 0 switches off the minimum
clearance check between copper and dimension. In this case EAGLE
doesnotrecognizeholesthatareplacedonwires.
Polygonsdon'tkeeptheirdistancetoobjectsinlayer20,Dimension,either!
Nets that belong to special net classes are an exception here. Values for
minimum clearance and hole diameters defined by means of the CLASS
command apply to these, provided they are higher than those given in
theDesignRules.
EAGLE's minimum resolution is 1/10.000 of a millimeter. That is why the
DRC can report only distance and clearance errors which are larger than
1/10.000mm.
Sizes
The minimum values for track width and for hole diameter allowed in
thelayoutareselectedhere.
Here you set the aspect ratio of drill depth to drill diameter for boards
that contain blind vias. Please contact your boardhouse for this infor
-
mation! If the boardhouse specifies, for example, an aspect ratio of
1:0.5 you have to enter the value 0.5 in the line Min. Blind Via Ratio.
For micro vias you have to set the minimum drill diameter in the line
Min. MicroVia. Setting this value higher than the value in Minimum
Drill meansthattherearenomicroviasused(default).
