FPCfab Description

FPCfab was developed to be a simple console application that creates a basic fabrication drawing based on information contained in a template RS-274X Gerber file and Excellon drill file generated by FreePCB. The new fab drawing is an RS-274X Gerber file that includes some or all of the data from the template file and adds a Drill Icon Table, Drill Targets and dimensions to the board outline. In addition to providing useful project documentation, some board houses prefer to use this type of drawing for drill data extraction. An optional holes file, also RS-274X, can be generated that contains the data from the NC Drill file translated into flashed apertures sized to match the drill sizes. Although ideal for depicting through holes when creating a blank board graphic with PBC-Render, its real purpose is that it is the preferred drill data format for some board houses. An optional annotation file can be used to add graphics and text to the fab drawing. The file uses a simple scripting language to generate graphic primitives and more complex objects many of which can be rendered as line graphics or as polygons. The template file need only contain the board outline(s) but, with some limitations, may include additional data. The NC drill file is used without modification. FPCfab uses a number of optional command line parameters to control its behavior. Each parameter is specified by a single character preceded by a dash (-) and may be followed immediately, without any spaces, by one or more text or numeric values. If embedded spaces are needed in the value, the whole field including the dash and parameter character must be enclosed in quotes. The parameter characters are not case sensitive.
