[. . . ] The DRC error window remains in the foreground. 106 From Schematic to Finished Board Clicking on the Del button will delete the selected error entry. Del all deletes all the error marks from the layout. The dialog is ended with Close. DRC error list in the Layout Editor Signal layers which are not visible (DISPLAY command) will not be checked by the Design Rule Check! Error messages and their meaning Angle: Tracks are not laid in an angle of 0, 45, 90 or 135°. This check can be switched on or off in the Design Rules (Misc tab). Clearance: Clearance violation between copper elements. The settings of the Design Rules' Clearance tab and the value for Clearance of a given net class will be checked. In addition the Isolate value will be taken into consideration for polygons with the same rank and polygons which are defined as part of a package. To deactivate the clearance check between elements that belong to the same signal, use the value 0 for Same signals in the Clearance tab. Dimension: Distance violation between smds, pads, and connected copper objects and a dimension line (drawn in Layer 20, Dimension), like the board's outlines. Defined through the value for Copper/Dimension in the 107 EAGLE Manual Design Rules (Distance tab). Setting the value Copper/Dimension to 0 deactivates this check. In this case polygons do not keep a minimum distance to objects in layer 20, Dimension, and holes!The DRC will not check if holes are placed on tracks!Drill Distance: Distance violation between holes. Defined by the value Drill/Hole in the Design Rules (Distance tab). Drill Size: Drill diameter violation in pads, vias, and holes. This value is defined in the Design Rules (Minimum Drill, Sizes tab). It is also possible to define a special value (Drills) for vias in a given net class (CLASS command). Keepout: Restricted areas for components drawn in layer 39, tKeepout, or 40, bKeepout, lie one upon another. No vector font: The font check (Design Rules, Misc tab) recognizes text in a signal layer which is not written in EAGLE's internal vector font. If you want to generate manufacturing data with the help of the CAM Processor the texts, at least in the signal layers, ought to be written in vector font. This is the only font the CAM Processor can work with.
