I think I'm beggining [...] Please try to turn on English spell checking in your email client, that makes it easier for us to read your postings -- please note not all of us have English as native language, so guessing the right words is not easy. (Guessing may be fun for some people -- for English my fear is that reading wrong spelling will make my own more bad than it already is :-( Thermals are not defined in footprints -- for pins and vias we use the thermal tool called THRM to make a thermal to the surrounding copper polygon. For pads we have to draw a trace to the copper polygon -- ensure that Settings->NewLinesClearPolygons is not selected in menu, or use j key when mouse hovers over an existing trace to make it connect to the polygon. For beginners I recommend DJ's tutorial http://www.delorie.com/pcb/docs/gs/gs.html For footprints we have the very verbose text http://www.brorson.com/gEDA/land_patterns_20070818.pdf I wrote a summary, see bottom of this page http://www.ssalewski.de/SFG.html.en Unfortunately that describes not the latest format -- I think we can use units like nm in footprint definition now, I will try to adapt that text when I have some spare time... Older footprints where created by m4 scripts with parameters indeed, but most people favorite the so called newlib footprints now, which are self contained and do not depend on m4 macro processor. A lot of tools exist to create footprints, some use textual description, some have graphical front-ends. Best regards, Stefan Salewski
