[. . . ] Activating the sub-option Persistent in this drawing saves the setting in the drawing file. If you send the layout file, for example, to the boardhouse you can be sure that the vector font will be displayed also at his system. 119 EAGLE Manual No real 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 although it is displayed as vector font in the Layout Editor window. This situation arises if the option Always vector font in the menu Options/User Interface is active. See error message No vector font for further details. Off Grid: The object does not fit onto the currently chosen grid. This check can be switched on or off in the Design Rules (Misc tab). Restrict: A wire drawn in layer 1, Top, or 16, Bottom, or a via lies in a restricted area which is defined in layer 41 or 42, t/bRestrict. Width: Minimum width violation of a copper object. Defined by Minimum Width in the Design Rules (Sizes tab) or, if defined, by the track parameter Width of a referring net class. Also texts in signal layers will be checked. Wire Style: The wire style of a wire which is connected to a signal is not Continuous. Net, device and pin lists can be output by means of EXPORT or by various User Language programs. Creating Manufacturing Data Prints of the layout can be created for purposes of documentation using the PRINT command. Layers that have been activated with DISPLAY are printed. The printout has the same appearance as the layout has on the screen. Exception: Origin marks of texts and grid lines are not printable. The manufacturing data is typically generated with the CAM Processor. A variety of drivers are available to create drilling data, Gerber data, plotter data and so forth. We will return to this subject in a specific chapter later. In order to save costs, it may be worth supplying the layout to the board manufacturer in the form of a multiple board. You can reproduce the layout to create a multiple board with the GROUP CUT and PASTE , commands. It should be noted that this will change the board's silk screen, since devices and signals receive new names when the layout is placed. Ensure that all the layers are displayed before using the GROUP and CUT commands. 120 From Schematic to Finished Board Any other data format can be created with the aid of ULPs (User Language programs). [. . . ] Error Messages When Loading a File Library objects with the same names. The text editor shows this message if you attempt to load an older file (BRD or SCH) that contains different versions of a library element. to the names of the devices so that they can be identified. This message can also appear if you use CUT and PASTE commands. 237 EAGLE Manual Pad, Via Replaced with a Hole In older versions of EAGLE it was possible to define pads in which the hole diameter was larger than the pad diameter. If you attempt to load a library file that was created with an earlier version and that contains such a pad, the following message appears: The pad or via is automatically converted into a hole, provided it is not connected by CONNECT to a pin in one of the library's devices.
