[. . . ] The width of the thermal connectors is calculated as the half of the pad's drill diameter. The width has to be in the limits of a minimum of the wire width and a maximum of twice the wire width of the polygon. Don't choose the polygon's width too fine, otherwise the thermal connectors won't carry the current load. Orphans: Defines whether the polygon may contain areas which are not connected electrically to polygon's signal or not. When drawing a polygon, please take care to ensure that the outline is not drawn more than once (overlapping) anywhere, and that the polygon outline does not cross over itself. It is not possible for EAGLE to compute the contents of the area in this case. If this message appears, the outline of the polygon must be corrected. The CAM Processor automatically computes the polygons in the layout before generating its output. Checking the Layout and Correcting Errors The Design Rule Check (DRC) is carried out at the end of the board design, if not before. If you have not yet specified any Design Rules for the layout, this is your last opportunity. If an error in the list is selected, a line points to the corresponding location. 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. 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°. 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). In this case polygons do not keep a minimum distance to objects in layer 20, Dimension, and holes!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. [. . . ] Default: off Pen Velocity in cm/s: This option is for pen plotters supporting different speeds. Offset X (Inch): This option can be used to move the origin of the drawing.
